94-715: See text. Nectandra is a genus of plant in the family Lauraceae . They are primarily Neotropical , with Nectandra coriacea being the only species reaching the southernmost United States. They have fruit with various medical effects. Sweetwood is a common name for some plants in this genus. They are trees and bushes , hermaphrodites . The leaves are alternate, entire, glabrous or pubescent pinnatinervias with longitudinal grooves. Simple, alternate, petiole 0.9 to 2.2 cm in length canalicular limbo 11 to 28 cm long and 5 to 11 cm wide, with 16–28 secondary veins; base acute decurrent and revolute, entire, apex elliptically shaped, green dark, and very oblique secondary veins visible on

188-452: A possible antitumoral agent, and the presence of neolignans suggests its potential use as a source of chemotherapeutics. Crude extracts of Nectandra contain alkaloids and lignans, berberine and sipirine. Some authors have postulated that tannins play important roles as antioxidant compounds in scavenging free radicals. It is reported that an extract of N. salicifolia has potent relaxant activity on vascular smooth muscle. Researchers around

282-551: A protective response. The first such plant receptors were identified in rice and in Arabidopsis thaliana . Plants have some of the largest genomes of all organisms. The largest plant genome (in terms of gene number) is that of wheat ( Triticum aestivum ), predicted to encode ≈94,000 genes and thus almost 5 times as many as the human genome . The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes. In terms of sheer DNA sequence,

376-420: A range of physical and biotic stresses which cause DNA damage , but they can tolerate and repair much of this damage. Plants reproduce to generate offspring, whether sexually , involving gametes , or asexually , involving ordinary growth. Many plants use both mechanisms. When reproducing sexually, plants have complex lifecycles involving alternation of generations . One generation, the sporophyte , which

470-494: A thin sheet of low-karat gold alloy , was used to wrap ceramic vessels for the lower elites, while the upper elites had high karat gold alloys. Common laborers only had arsenical copper objects. The precious metal objects then clearly demonstrate a hierarchy within the society (Shimada 2000, p. 56). No evidence of metalworking at the large sites has been uncovered, such as the Middle Sican capital Sican or elsewhere in

564-449: A way to symbolize their relationship to the divine. The sheer size and grandeur of the monumental mounds built above the elite tombs would have been awe-inspiring to Sicán citizens and a symbol the divine nature of the figures buried below. (Shimada et al. 2004) Colorful murals with religious iconography decorated ceremonial precincts in the temples of the mounds, establishing the sanctity of the ritual space, and reaffirming this connection of

658-404: Is diploid (with 2 sets of chromosomes ), gives rise to the next generation, the gametophyte , which is haploid (with one set of chromosomes). Some plants also reproduce asexually via spores . In some non-flowering plants such as mosses, the sexual gametophyte forms most of the visible plant. In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and

752-547: Is a similar process. Structures such as runners enable plants to grow to cover an area, forming a clone . Many plants grow food storage structures such as tubers or bulbs which may each develop into a new plant. Some non-flowering plants, such as many liverworts, mosses and some clubmosses, along with a few flowering plants, grow small clumps of cells called gemmae which can detach and grow. Plants use pattern-recognition receptors to recognize pathogens such as bacteria that cause plant diseases. This recognition triggers

846-562: Is characterized by the establishment of religious cities with monumental temples. The religious capital city and cultural center of the Middle Sicán is referenced as the Sicán Precinct. (Bruhns 1994, p. 293). This T-shaped area is defined by monumental mounds of Huaca Loro, El Moscón, Las Ventanas, La Merced, and Abejas built between around AD 900 and 1050. The pyramidal monumental mounds were used as both burials sites for

940-496: Is known as botany , a branch of biology . All living things were traditionally placed into one of two groups, plants and animals . This classification dates from Aristotle (384–322 BC), who distinguished different levels of beings in his biology , based on whether living things had a "sensitive soul" or like plants only a "vegetative soul". Theophrastus , Aristotle's student, continued his work in plant taxonomy and classification. Much later, Linnaeus (1707–1778) created

1034-468: Is revealed in varying burial types and practices, along with accompanying grave goods. The most obvious difference in burial type based on social hierarchy was that commoners were buried in simple, shallow graves on the peripheries of the monumental mounds while the elite of Sicán society were buried in deep shaft tombs beneath monumental mounds, as shown in the East and West tombs at Huaca Loro. Secondly, it

1128-697: Is similar to Ocotea , to which it is closely related. The most characteristic distinguishing features are the position of the locules in the anther (in an arc in Nectandra and two rows in Ocotea ); papillose pubescence is present; the Nectandra petals are fused at the base itself and fall as a unit in the old flowers; they are free in Nectandra but fall individually in Ocotea. Medium trees reach 60 cm in diameter and 25 m in height with straight, slender, cylindrical boles with low low and thin protuberances at

1222-632: The Antarctic flora , consisting of algae, mosses, liverworts, lichens, and just two flowering plants, have adapted to the prevailing conditions on that southern continent. Plants are often the dominant physical and structural component of the habitats where they occur. Many of the Earth's biomes are named for the type of vegetation because plants are the dominant organisms in those biomes, such as grassland , savanna , and tropical rainforest . Sican culture Archaeologist Izumi Shimada , founder of

1316-489: The Cloud forest determine the migratory movements of the quetzals to differing elevation levels in the forests. With a gape width of 21 mm, the quetzal swallows the small berries (aquacatillos) whole, which he catches while flying through the lower canopy of the tree, and then regurgitates the seed within 100 meters from the tree. Wheelwright, in 1983, observed that parent quetzals take far fewer time intervals to deliver fruits to

1410-706: The Cretaceous so rapid that Darwin called it an " abominable mystery ". Conifers diversified from the Late Triassic onwards, and became a dominant part of floras in the Jurassic . In 2019, a phylogeny based on genomes and transcriptomes from 1,153 plant species was proposed. The placing of algal groups is supported by phylogenies based on genomes from the Mesostigmatophyceae and Chlorokybophyceae that have since been sequenced. Both

1504-431: The adobe bricks used to make the mounds are indications of the patrons donating materials and/or labor for the construction of the temples (Shimada 2000, p. 60). This construction technique required "large-scale, unified construction with centrally pooled materials and labor force" (Shimada 2000 p. 60). It allowed for rapid erection of monumental buildings while minimizing labor and material investment and promoted

1598-457: The carpels or ovaries , which develop into fruits that contain seeds . Fruits may be dispersed whole, or they may split open and the seeds dispersed individually. Plants reproduce asexually by growing any of a wide variety of structures capable of growing into new plants. At the simplest, plants such as mosses or liverworts may be broken into pieces, each of which may regrow into whole plants. The propagation of flowering plants by cuttings

1692-1003: The "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis, as the land plants arose from within those groups. The classification of Bryophyta is supported both by Puttick et al. 2018, and by phylogenies involving the hornwort genomes that have also since been sequenced.

These include

1786-534: The Batán Grande area, but the precious metal objects were clearly for the elites. From their high status sites, the elites supervised the manufacturing of their precious metal objects for ritual or funerary purposes (Shimada and Merkel 1991, p. 86). Excavations of religious sites have revealed much about the funerary practices of the Sicán people. These funerary practices have helped anthropologists understand

1880-602: The Deity. The population of Batán Grande included many skilled artisans. Craft production during the Middle Sican flourished and became one of the leading characteristics of the period. The highly polished black finish ceramics from the Early Sican bloomed in this later phase, along with metallurgy ; however, the ceramic technology used in the Middle Sican developed over 2500 years from local pottery production techniques (Shimada and Wagner 2001, p. 26). Workshops, such as

1974-556: The Lambayeque Valley dating to the Sicán. The first type is the T-shaped mound, which is a relatively low mound with a short, central ramp providing direct access to the top of the mound. The second type is a relatively tall mound with steep sides and a zig-zagging ramp to provide circuitous access to the mound top. This second type also featured an enclosed structure at the top of the mound, likely for private rituals, whereas

2068-494: The Lambayeque region point to the convergence of major factors to allow such an occurrence: accessible ore deposits, extensive forests for hardwood to make charcoal, pottery making tradition using efficient kilns, gold working tradition that formed the basis for later metalworking technology, and a demand for goods by the elites (Shimada, Goldstein, Wagner, Bezur 2007, p. 339). The large number of smelting sites also point to

2162-518: The Late Sican and reflect the revitalization of the religion going back to tradition relationships with nature. Icons include felines, fish, and birds that were secondary to the Sican Deity during the previous era, but were also linked to previous cultures in the area. Sican material culture, such as ceramics and metallurgy, unrelated to religion or politics did not suffer a severe change during

2256-472: The Late Sican since the idea of mounds were not associated with the fall of the Middle Sican, only those mounds in Batán Grande. The same types of ceremonial and religious artifacts made from the same materials were found at Túcume. The site grew enormously during its 250-year Late Sican occupation. By the time of the Chimú conquest of the Lambayeque region in 1375, there were 26 major mounds and enclosures. The site

2350-429: The Middle Sican to Late Sican transition. Agriculture and irrigation were also not affected by the transition of political and religious power, as evidenced by the lack of effects on Pampa de Chaparri and numerous large urban hill-side settlements. Túcume took on the religious and ceremonial prestige as the site of Sican claimed during the Middle Sican. The mounds and temples from the Middle Sican were continued into

2444-519: The Motupe, La Leche, Lambayeque, and Zaña valleys, near modern-day Chiclayo . Numerous sites have been identified in the Batán Grande area of the La Leche Valley. The climate of the area during Sican occupation was similar to the current climate, despite changes in landscape accumulated in the last 600 years. The drought-and-flood cycles seen in the region for the past 1500 years did not spare

2538-706: The Sican Archaeological Project, named the prehistoric culture which he discovered in northwestern Peru. They succeeded the Moche and preceded the Inca Empire , the historical civilization that encountered the Spanish explorers and conquistadors . The Sican inhabited a coastal territory near the La Leche and Lambayeque Rivers . The archaeological sites span the Lambayeque region, including

2632-536: The Sican Deity It decorates all artistic media of the Sicán, including ceramics, metal works, and textiles. The icon is most commonly represented with a mask face and upturned eyes. Sometimes it may be shown with avian features, such as beaks, wings, and talons, which are evident in Early Sicán ceramics. These avian features are related to Naylamp , the key figure in Sicán mythology. The name "Naylamp"

2726-489: The Sican culture. (Goldstein and Shimada 2007, p. 49) The Early Sican period began around 750 and lasted until 900. The lack of artifacts has limited the development of knowledge about this early period. The Sican were probably descendants of the Moche culture, which fell around 800. Their works shows shared motifs in the artifacts recovered. Similar groups include Cajamarca , Wari , and Pachacamac . From remains found in

2820-444: The Sicán culture had a highly productive economy, clear social differentiation, and an influential religious ideology. The religious ideology was the underpinning of the structure of their theocratic state. Sicán art is representational in style and religious in nature. Features such as sculptural representation and the minimization of number of colors (one to three), were common among the art of many earlier cultures that flourished on

2914-479: The algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts , liverworts , mosses , lycophytes , ferns , conifers and other gymnosperms , and flowering plants ). A definition based on genomes includes the Viridiplantae, along with the red algae and the glaucophytes , in

3008-801: The amount of cytoplasm stays the same. Most plants are multicellular . Plant cells differentiate into multiple cell types, forming tissues such as the vascular tissue with specialized xylem and phloem of leaf veins and stems , and organs with different physiological functions such as roots to absorb water and minerals, stems for support and to transport water and synthesized molecules, leaves for photosynthesis, and flowers for reproduction. Plants photosynthesize , manufacturing food molecules ( sugars ) using energy obtained from light . Plant cells contain chlorophylls inside their chloroplasts, which are green pigments that are used to capture light energy. The end-to-end chemical equation for photosynthesis is: This causes plants to release oxygen into

3102-407: The amount of labor required by using their method. In modern standards, their copper-alloy smelting was inefficient, which could have led to the high number of workshops with multiple furnaces (Shimada and Merkel 1991, p. 85). The precious metal objects found in Middle Sican sites reveal the unprecedented scale of their production and use. Metal objects permeated all levels of society. Tumbaga ,

3196-478: The archaeological locations, researchers have determined that this culture maintained commercial exchange with people from present-day Ecuador (shells and snails), Colombia to the north ( emeralds and amber ), Chile to the south (blue stone), and the eastern basin of the Marañón River (seeds of gold ). The Lambayeque culture may have been a separate trading people as well. Around 800, the Sican created

3290-650: The area. Their materials came from mainly the northern Andes, such as Ecuador (from the Manteno and Milagro cultures), Peru, Colombia, but could have also reached as far south as the Tiwanaku empire in the south-central Andes and east to the Marañón River , a major tributary of the Amazon River . The Middle Sican trade networks appear to be unprecedented in range and goods involved, which helped to insure

3384-431: The atmosphere. Green plants provide a substantial proportion of the world's molecular oxygen, alongside the contributions from photosynthetic algae and cyanobacteria. Plants that have secondarily adopted a parasitic lifestyle may lose the genes involved in photosynthesis and the production of chlorophyll. Growth is determined by the interaction of a plant's genome with its physical and biotic environment. Factors of

3478-581: The base. The various species are located in the middle stratum of forests. Many species are used as timber. The family Lauraceae was part of the Gondwanaland flora, and many of its genera migrated to South America via Antarctica on ocean landbridges during the Paleocene era. There, they spread over most of the continent. When the North American and South American tectonic plates joined in

3572-467: The basis of the modern system of scientific classification , but retained the animal and plant kingdoms , naming the plant kingdom the Vegetabilia. When the name Plantae or plant is applied to a specific group of organisms or taxa , it usually refers to one of four concepts. From least to most inclusive, these four groupings are: There are about 382,000 accepted species of plants, of which

3666-450: The black ceramics, while only the social elite had access to the precious metal object; therefore, metalworking probably was given production preference by the elites (Goldsmith and Shimada 2007, p. 47). The greatness of Middle Sican metallurgy was the large-scale smelting and diverse use of arsenical copper , which was more ductile and corrosion-resistant than pure copper. The great amounts of smelting and/or metalworking sites found in

3760-540: The broader organization and structure of Sicán society and religion. Most of the evidence for these funerary practices has been based on excavations carried out at the Huaca Loro site in the city of Poma, located at Batán Grande, in La Leche Valley, by Izumi Shimada and the SAP. First of all, the funerary practices at Huaca Loro reflect the social differentiation and hierarchy present Sicán society. This social stratification

3854-542: The buried elite below to the divine. (Nickle Arts Museum 2006, Shimada et al. 2004) Also, the principal personage of the East Tomb at Huaca Loro wears a mask identical to the Sicán Deity, which is another reference to his relationship to the Deity and the divine. (Shimada et al. 2004, p. 389) The construction itself of these monumental mounds served as a reminder of the elite's power and endurance, and combined with

3948-406: The celestial world (Nickle Arts Museum 2006, p. 66; Shimada 2000, p. 52-53). Through the iconography which the Sicán associated with the icon, anthropologists theorize that the Sicán Deity may have been attributed with power to control all of the celestial forces fundamental to life and abundance (Shimada 2000, p. 53). the lack of representation of humans in Middle Sicán art emphasizes

4042-528: The centralization of political and religious power in order to plan and complete these monumental mounds. While the Sican ceramics and metallurgy are vastly studied, agriculture during the Middle to Late Sican may have been linked to their increasing craft production. Shimada suggests that the canals at Pampa de Chaparri were developed by the Sican as part of an agro-industrial complex marked by an increase in mining and smelting operations, settlement growth, and

4136-486: The city of Poma, located at Batán Grande , in La Leche Valley. Few other Early Sican sites have been discovered. The Early Sican culture is known for the highly polished, black-finish ceramics found in the La Leche Valley. This black-finish ceramic style began in the Moche culture prior to the Early Sican, and shows the sharing of cultures in the region. Much of the ceramics were examples of a single spout, loop-handle bottle, featuring an anthropomorphic -avian (bird) face at

4230-728: The clade Archaeplastida . There are about 380,000 known species of plants, of which the majority, some 260,000, produce seeds . They range in size from single cells to the tallest trees . Green plants provide a substantial proportion of the world's molecular oxygen; the sugars they create supply the energy for most of Earth's ecosystems and other organisms , including animals, either eat plants directly or rely on organisms which do so. Grain , fruit , and vegetables are basic human foods and have been domesticated for millennia. People use plants for many purposes , such as building materials , ornaments, writing materials , and, in great variety, for medicines . The scientific study of plants

4324-505: The combination of all the influences is Sican. The changing ceramic styles, iconography , and funerary practices reflect a change in religious ideology and cosmology that expressed the Sican culture. Most importantly, the late Early Sican period saw the accumulation of these changes in art style and iconography, coupled with other changes in organization, by which the Sican constructed monumental adobe structures, developed large-scale copper alloy smelting and metalworking , and developed

4418-411: The concept or representation of the icon of the Sicán Deity. Both the preceding Moche and Wari cultures feature a single dominant male figure, and the upturned eyes characteristic of the Sicán Deity are common to the art and iconography of other Pre-Hispanic societies. The iconography accompanying the Sicán Deity was unique and significant (Nickle Arts Museum 2006, p. 66). Iconography of the moon and

4512-488: The development of forests in swampy environments dominated by clubmosses and horsetails, including some as large as trees, and the appearance of early gymnosperms , the first seed plants . The Permo-Triassic extinction event radically changed the structures of communities. This may have set the scene for the evolution of flowering plants in the Triassic (~ 200  million years ago ), with an adaptive radiation in

4606-451: The drought that surely weakened agriculture in the area, the tolerance of the common population plummeted, forcing the removal of the political and religious leadership at Sican to save the people. There was little or no repair of the destruction of Sican, and further damage was inflicted by El Nino floods around 1100. The burning and abandonment of the previous capital meant that a new capital needed to be built. Túcume or "el Purgatorio"

4700-504: The elaborate funerary tradition that would come to characterize the Middle Sican (Shimada 1985, p. 361). Such changes have been seen by researchers at sites in Batán Grande, including the Huaca del Pueblo site, dated to around 850-900. The Middle Sican period lasted from 900 to 1100 . This is the period of the Sican's "cultural florescence", and is marked by the emergence of various cultural innovations, some of which were unprecedented in

4794-430: The elite and places of worship and ritual. The construction of the monumental mounds required considerable material, labor resources and time, indicating the Sicán elite's control and monopoly over the society's resources and manpower. They are a dramatic symbol of the power, wealth and permanence of the Middle Sicán elite and their theocratic state that dominated much of the north coast. Two types of mounds are found in

SECTION 50

4888-575: The elite included semi-precious stone objects, amber, feathers, textiles, imported shells (such as conus and spondylus ), shell beads, and double spout bottles. (Nickle Arts Museum 2006, p. 87; Shimada 2000, p. 56; Bruhns 1994, p. 290) On the other hand, commoner burials had a significantly less amount of grave goods of different types, made of less valuable materials. For example, commoner grave goods at Huaca Loro were usually restricted to single-spout bottles, utilitarian plain and/or paddle decorated pottery, and copper-arsenic objects, instead of

4982-494: The elite tombs at Huaca Loro, through the grouping and placement of bodies. The complex internal organization of both East and West Tombs was designed according to specific social and kinship relationships (Shimada et al. 2004). Recent studies that included the use of MtDNA (systematic mitochondrial DNA) analysis and inherited dental traits analysis revealed that women in the West Tomb were grouped according to their kinship ties to

5076-578: The entire world agree that extensive pre-clinical studies on herbal medicine are important and urgent, especially high-quality clinical and pre-clinical trials. In pre-Columbian Peru the seeds, called amala in Spanish, were used as a muscle relaxant. In sites of the Sican culture , collections of the seeds have been associated with human sacrifice, and used to incapacitate victims prior to being killed. Nectandra contains approximately 120 species, including

5170-405: The expansion of agriculture. Along the canals, 39 Middle Sican sites and 76 Late Sican sites were identified; however, few sites were located in the irrigation fields. This Sican occupation at the irrigation system points to its construction during the Middle Sican. The construction of this irrigation system, as well as the association of hierarchical social units and canal branches, coincides with

5264-585: The first dynasty of prehistoric kings in La Leche and Lambayeque valleys. In The Legend of Naylamp, first recorded in the 16th century by the Spanish chronicler Miguel Cabello de Balboa , Naylamp is said to have traveled on a balsa raft by sea to the Lambayeque shores. He founded a large city, and the 12 sons of his eldest son each founded a new city in the Lambayeque region. When Naylamp died, he sprouted wings and flew off to another world (Nickle Arts Museum 2006, p. 18 and 65). Middle Sicán art did not change

5358-617: The first type of mound was likely for public rituals (Shimada 2000, p. 60; Shimada, Shinoda, Farnum, Corruccini, Watanabe 2004, p. 388). The mounds also covered and protected the shafts of tombs of elites underneath. The Sicán used a walled-chamber-and-fill technique (which first appeared on the North Coast during Moche V) for constructing the monumental mound where the walls were created by adobe bricks and mortar in conjunction with chambers of superimposed lattices filled with refuse and other readily available materials. Marks on

5452-703: The fog-shrouded mountains of the Canary Islands, which, with Madagascar, constitutes Africa's Laurel forest plant refugia. In Meso-America, the genus Nectandra proliferated into new species, and some of its berries constitute a valuable food supply for the quetzal bird that lives in the montane rainforests. Since this habitat is constantly threatened by encroaching agriculture, the laurel forest animal and plant species have already become rare in many of its former habitats and are threatened by habitat loss. The quetzal's favorite fruits are berries of relatives of Nectandra umbrosa . Their differing maturing times in

This means that they obtain their energy from sunlight , using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll . Exceptions are parasitic plants that have lost

5828-499: The great complexity itself of elite burial practices based on social differentiation. Social stratification and hierarchy is also evidenced through the variation in quantity and quality of grave goods associated with those of different social status. The elite East Tomb at Huaca Loro, contained over a ton of diverse grave goods, over two-thirds of which were objects of arsenical bronze , tumbaga (low-karat gold), silver and copper alloys, and high-karat gold alloys. Other grave goods of

5922-583: The great majority, some 283,000, produce seeds . The table below shows some species count estimates of different green plant (Viridiplantae) divisions . About 85–90% of all plants are flowering plants. Several projects are currently attempting to collect records on all plant species in online databases, e.g. the World Flora Online . Plants range in scale from single-celled organisms such as desmids (from 10  micrometres   (μm) across) and picozoa (less than 3 μm across), to

6016-436: The help of the Middle Sican religious prestige. Only the geometric designs continued on the pottery into the Late Sican. Metallurgy is one of the Sican's greatest legacies, lasting nearly 600 years at Batán Grande (Shimada and Merkel 1991, p. 83). Some Middle Sican workshops showed multicraft production and it is likely the crafts competed for resources, such as fuel for kilns. Middle- and high-status burials both contained

6110-415: The kilns were used either for ceramics or metallurgy (Shimada and Wagner 2001, p. 28). The Paleteada ceramics used the paddle-and-anvil technique to form and decorate pottery, primarily with geometric designs (Cleland and Shimada 1998, p. 112). The monochrome black pottery became widely popular across the region during the Middle Sican as the Sican themselves began to emphasize the black pottery, with

6204-529: The land 1,200  million years ago , but it was not until the Ordovician , around 450  million years ago , that the first land plants appeared, with a level of organisation like that of bryophytes. However, fossils of organisms with a flattened thallus in Precambrian rocks suggest that multicellular freshwater eukaryotes existed over 1000 mya. Primitive land plants began to diversify in

6298-412: The large water-filled central vacuole , chloroplasts , and the strong flexible cell wall , which is outside the cell membrane . Chloroplasts are derived from what was once a symbiosis of a non-photosynthetic cell and photosynthetic cyanobacteria . The cell wall, made mostly of cellulose , allows plant cells to swell up with water without bursting. The vacuole allows the cell to change in size while

6392-515: The largest trees ( megaflora ) such as the conifer Sequoia sempervirens (up to 120 metres (380 ft) tall) and the angiosperm Eucalyptus regnans (up to 100 m (325 ft) tall). The naming of plants is governed by the International Code of Nomenclature for algae, fungi, and plants and the International Code of Nomenclature for Cultivated Plants . The ancestors of land plants evolved in water. An algal scum formed on

6486-665: The late Silurian , around 420  million years ago . Bryophytes, club mosses, and ferns then appear in the fossil record. Early plant anatomy is preserved in cellular detail in an early Devonian fossil assemblage from the Rhynie chert . These early plants were preserved by being petrified in chert formed in silica-rich volcanic hot springs. By the end of the Devonian, most of the basic features of plants today were present, including roots, leaves and secondary wood in trees such as Archaeopteris . The Carboniferous period saw

6580-757: The late Neogene, volcanic mountains started creating island chains, later forming the Meso-American landbridge. Pliocene elevation created new habitats for speciation. While some genera died out in increasingly xerophytic Africa, starting with the freezing of Antarctica about 20 million years ago and the formation of the Benguela current, others, like Beilschmiedia and Nectandra , which also reached south and meso-America, are still surviving today in Africa in several species. The genus Persea , however, died out in Africa, except for Persea indica , surviving in

6674-420: The living elite. (Shimada et al. 2004, p. 389) The variety of grave goods suggests the wide range of power of the Middle Sican elite. They not only received the most grave offerings, but also the best quality and exotic offerings. None of the metalworking sites showed evidence of on-site mining of any of the materials. In addition, the spondylus shell, emeralds, feathers, and other minerals were imported to

6768-649: The local area. The decline of the Wari Empire and the Middle Cajamarca polity enabled the resurgence in local political and religious identity and autonomy. The Middle Sican culture is marked by distinctive characteristics in six areas: art and ideology, crafts and technology, funerary customs, long-distance trade, religious cities and monumental temples, and the structure and authority of the state (Shimada 2000, p. 52-61; Shimada 1985, p. 365-369). Together, these characteristics provide evidence that

6862-509: The monumental mound at Huaca Loro, the preparation of the East and West Tombs and performance of the associated rituals required careful and complex planning, and considerable material, labor resources and time, and suggests the elite's control and monopoly of power in society. Secondly, the funerary practices of the Sicán suggest the existence of an elite lineage that used the new Sicán religion to demonstrate and maintain their power (Shimada et al. 2004). The Sicán elite used funerary practices as

6956-461: The north coast of Peru. Sicán art reconfigured the motifs, conventions, and concepts of these antecedent cultures (mainly the Wari and Moche) into an overall new and unique style. The references to the old ideas, images and ways of antecedent cultures in Sicán art would have been useful in providing prestige and legitimacy to the new Sicán religion which was emerging. Sicán iconography is dominated by

7050-440: The ocean may symbolize the Sicán Deity's involvement in the wellbeing of marine life and fishermen. Iconography related to water signifies the importance of irrigation and agriculture to the Sicán. Other iconography, such as of the sun and moon, symbolizes the importance of duality in both human and celestial life. Depictions of the Sicán Deity with tumi knives and trophy heads may indicate his omnipotent control in both human life and

7144-468: The omnipresence of the Sicán Deity in Sicán iconography. The only exceptions are representations of the Sicán Lord, the male elite personage, and his entourage. (Shimada 2000, p. 53) Iconography of the Sicán Lord is almost identical to the Sicán Deity, except that he is shown in natural settings and does not have avian features. The Sicán Lord was probably meant to represent an earthly alter-ego of

7238-628: The one found at Huaca Sialupe to the west of Batán Grande, likely had both pottery and metalworking production sites (Goldsmith and Shimada 2007, p. 45). Ceramics allowed for a medium to convey political and religious ideology in the forms of storage vessels, architectural ornaments, cooking vessels, sculptures of the Deity or animals, and other types proliferated during this period. The potters likely worked separately from one another, rather than in assembly-line type production. Huaca Sialupe excavations produced clusters of similar kilns using local hardwood for charcoal . Field experiments indicated that

7332-435: The people. The elites were the mediators between the common people and the Sican Deity, as the Sican Deity was the mediator between nature and the Sican people. After 30 years of uncertainty in respect to nature, the temples that were the center of Middle Sican religion and elite power were burned and abandoned between 1050 and 1100. Perhaps the ancestor cult and aggrandizing of the elites caused too much resentment. Coupled with

7426-501: The physical or abiotic environment include temperature , water , light, carbon dioxide , and nutrients in the soil. Biotic factors that affect plant growth include crowding, grazing, beneficial symbiotic bacteria and fungi, and attacks by insects or plant diseases . Frost and dehydration can damage or kill plants. Some plants have antifreeze proteins , heat-shock proteins and sugars in their cytoplasm that enable them to tolerate these stresses . Plants are continuously exposed to

7520-418: The precious metal objects of the elite tombs. (Nickle Arts Museum 2006, p. 87, Shimada et al. 2004) The power of the elite of Sicán society is demonstrated not only by the amount, quality, and diversity of exotic and status goods accumulated in the tombs, but also by the amount of time and labor that would have gone into making and acquiring them. (Shimada 2000, p. 56) All together, the construction of

7614-404: The principal personage and each other (Shimada et al. 2005; Shimada et al. 2004). The grouping of women in the south part of the West Tomb were found to be maternally related to one another, as well as the principal personage; the grouping of women in the north part of the West Tomb were found to not only be unrelated to one another, but also unrelated to the principal personage. Further, ceramics in

7708-556: The principal personage or each other therefore were placed and grouped according to some other distinct relationship to the principal personage. This genetic evidence and along with the differing styles of ceramics suggests that the North-niche women of the West Tomb were perhaps descendants of a different ethnic group, the Moche, who had been integrated into Sicán society under political domination (Shimada et al. 2004). While these relationships have not been proved definitively, it shows

7802-416: The rapid and dramatic growth of the Middle Sican. Irrigation for agriculture was a necessity for the Sican elite to produce a surplus of food to feed artisans and laborers, who in turn support the elites. The Late Sican period began around 1100 and ended with the conquest of the Lambayeque region by the Chimú kingdom of Chimor circa 1375. Around 1020, a major drought lasting 30 years occurred at Sican. At

7896-469: The smallest published genome is that of the carnivorous bladderwort ( Utricularia gibba) at 82 Mb (although it still encodes 28,500 genes) while the largest, from the Norway spruce ( Picea abies ), extends over 19.6 Gb (encoding about 28,300 genes). Plants are distributed almost worldwide. While they inhabit several biomes which can be divided into a multitude of ecoregions , only the hardy plants of

7990-557: The south part were found to be of typical Middle Sicán style, while the ceramics in the North part were of a Mochica style (Shimada et al. 2005; Shimada et al. 2004). This evidence suggests that while the women of the South part of the West tomb were grouped and placed according to their kinship ties with the principal personage, the women of the North part of the West tomb had no kinship ties with

8084-529: The spout base. The face consisted of bulging eyes, a hooked beak or triangular projection instead of a nose, stylized ears, and no mouth. It appeared to be a predecessor to the related faces of the Sican Deity and the Sican Lord of the Middle Sican culture. (Shimada 2000, p. 51) Aside from the shared ceramic styles, much of the Early Sican defines a distinguishable culture. While the ceramic styles and iconography show some continuity with previous cultures,

8178-476: The spread of Sican religion and polity outside of the Lambayeque and La Leche valleys (Shimada 2000, p. 58). They also could have controlled the transport methods in addition to the goods being traded. The breeding and herding of llamas on the North Coast since the time of the Moche could have been utilized by the Sican to provide the goods as well as a caravan of llamas to transport the goods considerable distances (Shimada 1985, p. 391). The Sicán culture

8272-404: The symbolic use of Sicán religious iconography to justify the divine merits of the elite lineage, was an attempt by the Sicán elite to "preserve the status quo of inherited rights." (Shimada et al. 2004, p. 370) The funerary rites and rituals performed by the living lineage members served to further reinforce their lineage identity and the three-way relationship between the divine, the dead, and

8366-421: The time of the drought, the Sican Deity, so closely tied to the ocean and water in general, was at the center of Sican religion. The catastrophic changes in weather were thus linked to the Sican Deity, mainly to the failure of the Sican Deity to mediate nature for the Sican people. The Sican ceremonies (and temples/mounds on which they were performed) were supposed to ensure that there was an abundance of nature for

8460-406: The underside. Terminal buds are whitish. The inflorescences are pseudo-axillary and paniculate, the last divisions cimosas, mostly somewhat pubescent, the flowers are small, rarely more than 1 cm in diameter, and white or greenish tepals equal. The fruit is an ovoid, fleshy drupe with a reddish-pink dome, green when immature and black when ripe. A neotropical genus with 114 species, Nectandra

8554-637: The young brood than insects or lizards, reflecting the ease of procuring fruits, as opposed to capturing animal prey. Since the young are fed exclusively berries in the first two weeks after hatching, these berries must be highly nutritional. Usually, only the total percentage of water, sugar, nitrogen, crude fats and carbohydrates are reported by ornithologists. Plants from this genus have been used to treat several human clinical disorders. It has been demonstrated that Nectandra plants have potential for analgesic, anti-inflammatory, febrifuge, energetic, and hypotensive activities. Nectandra has also been investigated as

8648-423: Was constructed as the new Late Sican capital at the juncture of the La Leche and Lambayeque Valleys. Túcume became the new religious and ceremonial center of the Sican. The religious and iconographic legacies of the Middle Sican abruptly disappeared. It is at this juncture, when the Sican Deity and Sican Lord disappear from art, is when the Late Sican begins. Other mythical depictions from the Middle Sican continued in

8742-462: Was first mentioned by the Spanish chronicler Miguel Cabello Valboa , who referred to the Moche figure "Naymlap" in his 1586 Miscelánea Antártica . Later authors believe the form is Mochica Ñañlap , of which the first part is ñañ "waterfowl"; a connexion has been made between the Moche and Chimú cultures and the empire of Chimor and the Mochica language. Naylamp was said to be the founder of

8836-460: Was found that one's social status was also a determinant of the burial position of the body; seated, extended, or flexed. For example, bodies of the High Elite were always buried in the seated position, while commoners could be buried in a seated, extended, or flexed position (Nickle Arts Museum 2006, p. 87; Shimada et al. 2004). Furthermore, social differentiation is manifested even within
