Humans first migrated to Australia at least 65,000 years ago, and over time formed as many as 500 language-based groups . In the past, Aboriginal people lived over large sections of the continental shelf . They were isolated on many of

This suggests that a population split from the common ancestor of Aboriginal Australians and Papuans. The sample also shows genetic affinity with East Asians and the Andamanese people of South Asia. The authors note that this hunter-gatherer sample can be modelled with ~50% Papuan-related ancestry and either with ~50% East Asian or Andamanese Onge ancestry, highlighting

In addition, a zone of permafrost stretched southward from the edge of the glacial sheet, a few hundred kilometres in North America , and several hundred in Eurasia . The mean annual temperature at the edge of the ice was −6 °C (21 °F); at the edge of the permafrost, 0 °C (32 °F). Each glacial advance tied up huge volumes of water in continental ice sheets 1,500 to 3,000 metres (4,900–9,800 ft) thick, resulting in temporary sea-level drops of 100 metres (300 ft) or more over

However, a 2016 study in Current Biology by Anders Bergström et al. excluded the Y chromosome as providing evidence for recent gene flow from India into Australia. The study authors sequenced 13 Aboriginal Australian Y chromosomes using recent advances in gene sequencing technology.

In the 1560s, the Spanish established colonies in Florida and in 1598 founded
10725-447: The United Nations (UN) adopted a Declaration on the Rights of Indigenous Peoples including their rights to self-determination and to protect their cultures, identities, languages, ceremonies, and access to employment, health, education and natural resources. Indigenous peoples continue to face threats to their sovereignty, economic well-being, languages, cultural heritage, and access to the resources on which their cultures depend. In
10868-535: The Younger Dryas is the official start of the current Holocene Epoch . Although it is considered an epoch, the Holocene is not significantly different from previous interglacial intervals within the Pleistocene. In the ICS timescale, the Pleistocene is divided into four stages or ages , the Gelasian , Calabrian , Chibanian (previously the unofficial "Middle Pleistocene"), and Upper Pleistocene (unofficially
11011-564: The ancestors of the Greeks , or as an earlier group of people who inhabited Greece before the Greeks. The disposition and precise identity of this former group is elusive, and sources such as Homer , Hesiod and Herodotus give varying, partially mythological accounts. Dionysius of Halicarnassus in his book, Roman Antiquities , gives a synoptic interpretation of the Pelasgians based on
11154-442: The ancient people expanded and differentiated into distinct groups, each with its own language and culture. More than 400 distinct Australian Aboriginal peoples have been identified, distinguished by names designating their ancestral languages, dialects, or distinctive speech patterns. According to noted anthropologist , archaeologist and sociologist Harry Lourandos , historically, these groups lived in three main cultural areas,
11297-706: The appearance of Homo sapiens about 300,000 years ago. Artifacts associated with modern human behavior are unambiguously attested starting 40,000–50,000 years ago. According to mitochondrial timing techniques, modern humans migrated from Africa after the Riss glaciation in the Middle Palaeolithic during the Eemian Stage , spreading all over the ice-free world during the late Pleistocene. A 2005 study posits that humans in this migration interbred with archaic human forms already outside of Africa by
11440-527: The articles for those names. Both marine and continental faunas were essentially modern but with many more large land mammals such as Mammoths , Mastodons , Diprotodons , Smilodons , tigers , lions , Aurochs , short-faced bears , giant sloths , species within Gigantopithecus and others. Isolated landmasses such as Australia , Madagascar , New Zealand and islands in the Pacific saw
11583-445: The basis of their continued existence as peoples, in accordance with their own cultural patterns, social institutions and legal systems. Martínez Cobo states that the following factors are relevant to historical continuity: occupation of ancestral lands, or at least of part of them; common ancestry with the original occupants of these lands; cultural factors such as religion, tribalism, dress, etc.; language; residence in certain parts of
11726-685: The circumstances of the people would allow them to exercise. ... [This loss of native property and sovereignty rights was justified, the Court said, by] the character and religion of its inhabitants ... the superior genius of Europe ... [and] ample compensation to the [Indians] by bestowing on them civilization and Christianity, in exchange for unlimited independence. Estimates of the population of Indigenous peoples range from 250 million to 600 million. The United Nations estimates that there are over 370 million Indigenous people living in over 90 countries worldwide. This would equate to just fewer than 6% of
11869-538: The climate variation more extreme. The Late Pleistocene witnessed the spread of modern humans outside of Africa as well as the extinction of all other human species. Humans also spread to the Australian continent and the Americas for the first time, co-incident with the extinction of most large-bodied animals in these regions. The aridification and cooling trends of the preceding Neogene were continued in
12012-737: The colonists and the progressive dispossession of their traditional lands. In 1492, the population of the Americas as a whole was about 50 to 100 million. By 1700, introduced diseases had reduced the native population by 90%. European migration and transfer of slaves from Africa reduced the native population to a minority. By 1800 the population of North America comprised about 5 million Europeans and their descendants, one million Africans and 600,000 indigenous Americans. Native populations also encountered new animals and plants introduced by Europeans. These included pigs, horses, mules, sheep and cattle; wheat, barley, rye, oats, grasses and grapevines. These exotic animals and plants radically transformed
12155-678: The convention covers: peoples in independent countries who are regarded as indigenous on account of their descent from the populations which inhabited the country, or a geographical region to which the country belongs, at the time of conquest or colonisation or the establishment of present state boundaries and who, irrespective of their legal status, retain some or all of their own social, economic, cultural and political institutions. The convention also covers "tribal peoples" who are distinguished from Indigenous peoples and described as "tribal peoples in independent countries whose social, cultural and economic conditions distinguish them from other sections of
12298-541: The country, or in certain regions of the world; and other relevant factors. In 2004, James Anaya , defined Indigenous peoples as "living descendants of pre-invasion inhabitants of lands now dominated by others. They are culturally distinct groups that find themselves engulfed by other settler societies born of forces of empire and conquest". In 2012, Tuck and Yang propose a criterion based on accounts of origin: "Indigenous peoples are those who have creation stories, not colonization stories, about how we/they came to be in
12441-515: The deep split between Leang Panninge and Aboriginal/Papuans. Mallick et al. 2016 and Mark Lipson et al. 2017 study found the bifurcation of Eastern Eurasians and Western Eurasians dates to least 45,000 years ago, with indigenous Australians nested inside the Eastern Eurasian clade. Two genetic studies by Larena et al. 2021 found that Philippines Negrito people split from the common ancestor of Aboriginal Australians and Papuans before
12584-496: The desert-dwelling Pitjantjatjara people compared with a group of European people showed that the cooling adaptation of the Aboriginal group differed from that of the white people, and that they were able to sleep more soundly through a cold desert night. A 2014 Cambridge University study found that a beneficial mutation in two genes which regulate thyroxine , a hormone involved in regulating body metabolism , helps to regulate body temperature in response to fever. The effect of this
12727-540: The end of the last glacial period and also with the end of the Paleolithic age used in archaeology . The name is a combination of Ancient Greek πλεῖστος ( pleîstos ) 'most' and καινός ( kainós ; Latinized as cænus ) 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama , causing a faunal interchange between
12870-618: The entire surface of the Earth. During interglacial times, such as at present, drowned coastlines were common, mitigated by isostatic or other emergent motion of some regions. The effects of glaciation were global. Antarctica was ice-bound throughout the Pleistocene as well as the preceding Pliocene. The Andes were covered in the south by the Patagonian ice cap. There were glaciers in New Zealand and Tasmania . The current decaying glaciers of Mount Kenya , Mount Kilimanjaro , and
13013-782: The evolution of large birds and even reptiles such as the Elephant bird , moa , Haast's eagle , Quinkana , Megalania and Meiolania . The severe climatic changes during the Ice Age had major impacts on the fauna and flora. With each advance of the ice, large areas of the continents became depopulated, and plants and animals retreating southwards in front of the advancing glacier faced tremendous stress. The most severe stress resulted from drastic climatic changes, reduced living space, and curtailed food supply. A major extinction event of large mammals ( megafauna ), which included mammoths , mastodons , saber-toothed cats , glyptodons ,
13156-579: The exploitation of natural resources, spreading Christianity, and establishing strategic military bases, colonies and settlements. From 1492, the Arawak peoples of the Caribbean islands encountered Spanish colonizers initially led by Christopher Columbus . The Spanish enslaved some of the native population and forced others to work on farms and gold mines in a system of labor called encomienda . Spanish settlements spread from Hispaniola to Puerto Rico,
13299-524: The following "working definition" : Indigenous communities, peoples, and nations are those that, having a historical continuity with pre-invasion and pre-colonial societies that developed on their territories, consider themselves distinct from other sectors of the societies now prevailing in those territories, or parts of them. They form at present non-dominant sectors of society and are determined to preserve, develop, and transmit to future generations their ancestral territories, and their ethnic identity, as
13442-414: The glacial range, which have their own glacial history depending on latitude, terrain and climate. There is a general correspondence between glacials in different regions. Investigators often interchange the names if the glacial geology of a region is in the process of being defined. However, it is generally incorrect to apply the name of a glacial in one region to another. For most of the 20th century, only
13585-713: The haplogroup C chromosomes. They found a divergence time of about 54,100 years between the Sahul C chromosome and its closest relative C5, as well as about 54,300 years between haplogroups K*/M and their closest haplogroups R and Q. The deep divergence time of 50,000-plus years with the South Asian chromosome and "the fact that the Aboriginal Australian Cs share a more recent common ancestor with Papuan Cs" excludes any recent genetic contact. The 2016 study's authors concluded that, although this does not disprove
13728-450: The historical terminology was established. Corresponding to the terms glacial and interglacial, the terms pluvial and interpluvial are in use (Latin: pluvia , rain). A pluvial is a warmer period of increased rainfall; an interpluvial is of decreased rainfall. Formerly a pluvial was thought to correspond to a glacial in regions not iced, and in some cases it does. Rainfall is cyclical also. Pluvials and interpluvials are widespread. There
13871-400: The idea of ancient Aboriginal isolation. Genetic data extracted in 2011 by Morten Rasmussen et al., who took a DNA sample from an early-20th-century lock of an Aboriginal person's hair, found that the Aboriginal ancestors probably migrated through South Asia and Maritime Southeast Asia , into Australia, where they stayed. As a result, outside of Africa, the Aboriginal peoples have occupied
14014-650: The increased suicide rate, many researchers have suggested that the inclusion of more cultural aspects into suicide prevention programs would help to combat mental health issues within the community. Past studies have found that many indigenous leaders and community members, do in fact, want more culturally-aware health care programs. Similarly, culturally-relative programs targeting indigenous youth have actively challenged suicide ideation among younger indigenous populations, with many social and emotional wellbeing programs using cultural information to provide coping mechanisms and improving mental health. The outstation movement of
14157-510: The indigenous populations of Borneo and Malaysia , sharing drift with them than compared to the groups from Papua New Guinea and Indonesia. This indicates that populations in Australia were isolated for a long time from the rest of Southeast Asia. They remained untouched by migrations and population expansions into that area, which can be explained by the Wallace line . In a 2001 study, blood samples were collected from some Warlpiri people in
14300-432: The involvement of the French, Dutch and English, before declining in the 19th century. At least 12 million slaves were transported from Africa. The slave trade increased inter-tribal warfare and stunted population growth and economic development in the west African interior. Indigenous encounters with Europeans increased during the age of discovery . The Europeans were motivated by a range of factors including trade,
14443-566: The islands of Tasmania , K'gari (previously Fraser Island) , Hinchinbrook Island , the Tiwi Islands , Kangaroo Island and Groote Eylandt . Indigenous people of the Torres Strait Islands, however, are not Aboriginal. In the 2021 census , people who self-identified on the census form as being of Aboriginal and/or Torres Strait Islander origin totalled 812,728 out of a total of 25,422,788 Australians, equating to 3.2% of Australia's population and an increase of 163,557 people, or 25.2%, since
14586-454: The land was inundated at the start of the Holocene , the inter-glacial period that started about 11,700 years ago. Scholars of this ancient history believe that it would have been difficult for Aboriginal people to have originated purely from mainland Asia. Not enough people would have migrated to Australia and surrounding islands to fulfill the beginning of the size of the population seen in
14729-622: The large amounts of material moved about by glaciers. Less common are cave deposits, travertines and volcanic deposits (lavas, ashes). Pleistocene marine deposits are found primarily in shallow marine basins mostly (but with important exceptions) in areas within a few tens of kilometres of the modern shoreline. In a few geologically active areas such as the Southern California coast, Pleistocene marine deposits may be found at elevations of several hundred metres. The modern continents were essentially at their present positions during
14872-405: The last 10,000 years it may have occurred—newer analytical techniques have the potential to address such questions. Bergstrom's 2018 doctoral thesis looking at the population of Sahul suggests that other than relatively recent admixture, the populations of the region appear to have been genetically independent from the rest of the world since their divergence about 50,000 years ago. He writes "There
15015-521: The latter two diverged from each other, but after their common ancestor diverged from the ancestor of East Asian peoples . The dingo reached Australia about 4,000 years ago. Near that time, there were changes in language (with the Pama-Nyungan language family spreading over most of the mainland), and in stone tool technology. Smaller tools were used. Human contact has thus been inferred, and genetic data of two kinds have been proposed to support
15158-496: The likely migration routes of the peoples as they moved across the Australian continent to its southern reaches and what is now Tasmania , then part of the mainland. The modelling is based on data from archaeologists , anthropologists , ecologists , geneticists , climatologists , geomorphologists , and hydrologists . It is intended to compare this data with the oral histories of Aboriginal peoples, including Dreaming stories, Australian rock art , and linguistic features of
15301-406: The local environment and disrupted traditional agriculture and hunting practices. The indigenous populations of the Pacific had increasing contact with Europeans in the 18th century as British, French and Spanish expeditions explored the region. The natives of Tahiti had encounters with the expeditions of Wallis (1766), Bougainville (1768), Cook (1769) and many others before being colonized by
15444-470: The lower Palaeolithic they disappeared, and the only hominin species found in fossilic records is Homo erectus for much of the Pleistocene. Acheulean lithics appear along with Homo erectus , some 1.8 million years ago, replacing the more primitive Oldowan industry used by A. garhi and by the earliest species of Homo . The Middle Paleolithic saw more varied speciation within Homo , including
15587-423: The many Aboriginal languages which reveal how the peoples developed separately. The routes, dubbed "superhighways" by the authors, are similar to current highways and stock routes in Australia. Lynette Russell of Monash University believes that the new model is a starting point for collaboration with Aboriginal people to help reveal their history. The new models suggest that the first people may have landed in
15730-478: The megafauna and migrated north. Late Pleistocene bighorn sheep were more slender and had longer legs than their descendants today. Scientists believe that the change in predator fauna after the late Pleistocene extinctions resulted in a change of body shape as the species adapted for increased power rather than speed. The extinctions hardly affected Africa but were especially severe in North America where native horses and camels were wiped out. In July 2018,
15873-403: The micro-level (tribe, clan, etc.), and others on shared languages and cultural practices spread over large regions defined by ecological factors. Anthropologists have encountered many difficulties in trying to define what constitutes an Aboriginal people/community/group/tribe, let alone naming them. Knowledge of pre-colonial Aboriginal cultures and societal groupings is still largely dependent on
16016-551: The national community and whose status is regulated wholly or partially by their own customs or traditions or by special laws or regulations." The convention states that self-identification as indigenous or tribal is a fundamental criterion for determining the groups to which the convention applies. The UN Declaration on the Rights of Indigenous Peoples does not define Indigenous peoples but affirms their right to self-determination including determining their own identity. The Inter-American Commission on Human Rights does not provide
16159-406: The observers' interpretations, which were filtered through colonial ways of viewing societies. Some Aboriginal peoples identify as one of several saltwater, freshwater, rainforest or desert peoples . The term Aboriginal Australians includes many distinct peoples who have developed across Australia for over 50,000 years. These peoples have a broadly shared, though complex, genetic history, but it
16302-581: The older Pliocene Epoch , which Lyell had originally thought to be the youngest fossil rock layer. He constructed the name "Pleistocene" ('most new' or 'newest') from the Greek πλεῖστος ( pleīstos ) 'most' and καινός ( kainós ( Latinized as cænus ) 'new'). This contrasts with the immediately preceding Pliocene ("newer", from πλείων ( pleíōn , "more") and kainós ) and the immediately subsequent Holocene ("wholly new" or "entirely new", from ὅλος ( hólos , "whole") and kainós ) epoch , which extends to
16445-414: The oldest continuous cultures in the world, although this is disputed. At the time of European colonisation of Australia, the Aboriginal people consisted of complex cultural societies with more than 250 languages and varying degrees of technology and settlements. Languages (or dialects) and language-associated groups of people are connected with stretches of territory known as "Country", with which they have
16588-636: The oldest living populations in the world, certainly the oldest outside of Africa." Their ancestors left the African continent 75,000 years ago. They may have the oldest continuous culture on earth. In Arnhem Land in the Northern Territory , oral histories comprising complex narratives have been passed down by Yolngu people through hundreds of generations. The Aboriginal rock art , dated by modern techniques, shows that their culture has continued from ancient times. The ancestors of present-day Aboriginal Australian people migrated from Southeast Asia by sea during
16731-418: The original 250–400 Aboriginal languages (more than 250 languages and about 800 dialectal varieties on the continent) are endangered or extinct, although some efforts are being made at language revival for some. As of 2016, only 13 traditional Indigenous languages were still being acquired by children, and about another 100 spoken by older generations only. Dispersing across the Australian continent over time,
16874-420: The other studies had utilised complete Y chromosome sequencing, which has the highest precision. For example, use of a ten Y STRs method has been shown to massively underestimate divergence times. Gene flow across the island-dotted 150-kilometre-wide (93 mi) Torres Strait, is both geographically plausible and demonstrated by the data, although at this point it could not be determined from this study when within
17017-506: The population of Indigenous peoples range from 250 million to 600 million. There are some 5,000 distinct Indigenous peoples spread across every inhabited climate zone and inhabited continent of the world. Most Indigenous peoples are in a minority in the state or traditional territory they inhabit and have experienced domination by other groups, especially non-Indigenous peoples. Although many Indigenous peoples have experienced colonization by settlers from European nations, Indigenous identity
17160-440: The presence of any Holocene gene flow or non-genetic influences from South Asia at that time, and the appearance of the dingo does provide strong evidence for external contacts, the evidence overall is consistent with a complete lack of gene flow, and points to indigenous origins for the technological and linguistic changes. They attributed the disparity between their results and previous findings to improvements in technology; none of
17303-465: The present time. The Pleistocene has been dated from 2.580 million (±0.005) to 11,700 years BP with the end date expressed in radiocarbon years as 10,000 carbon-14 years BP. It covers most of the latest period of repeated glaciation , up to and including the Younger Dryas cold spell. The end of the Younger Dryas has been dated to about 9700 BCE (11,700 calendar years BP). The end of
17446-410: The previous census in 2016. Reasons for the increase were broadly as follows: Most Aboriginal people speak English, with Aboriginal phrases and words being added to create Australian Aboriginal English (which also has a tangible influence of Aboriginal languages in the phonology and grammatical structure ). Some Aboriginal people, especially those living in remote areas, are multi-lingual. Many of
17589-416: The principles of the discovery doctrine: The United States ... [and] its civilized inhabitants now hold this country. They hold, and assert in themselves, the title by which it was acquired. They maintain, as all others have maintained, that discovery gave an exclusive right to extinguish the Indian title of occupancy, either by purchase or by conquest; and gave also a right to such a degree of sovereignty, as
17732-417: The ratio of O to O (two isotopes of oxygen ) by mass (measured by a mass spectrometer ) present in the calcite of oceanic core samples is used as a diagnostic of ancient ocean temperature change and therefore of climate change. Cold oceans are richer in O , which is included in the tests of the microorganisms ( foraminifera ) contributing the calcite. A more recent version of
17875-485: The remaining land bridge was impassable. This isolation makes the Aboriginal people the world's oldest culture. The study also found evidence of an unknown hominin group, distantly related to Denisovans, with whom the Aboriginal and Papuan ancestors must have interbred, leaving a trace of about 4% in most Aboriginal Australians' genome. There is, however, increased genetic diversity among Aboriginal Australians based on geographical distribution. Carlhoff et al. 2021 analysed
18018-570: The revised definition of the Quaternary , by pushing back the start date of the Pleistocene to 2.58 Ma, results in the inclusion of all the recent repeated glaciations within the Pleistocene. Radiocarbon dating is considered to be inaccurate beyond around 50,000 years ago. Marine isotope stages (MIS) derived from Oxygen isotopes are often used for giving approximate dates. Pleistocene non-marine sediments are found primarily in fluvial deposits , lakebeds, slope and loess deposits as well as in
18161-403: The same territory continuously longer than any other human populations. These findings suggest that modern Aboriginal Australians are the direct descendants of the eastern wave, who left Africa up to 75,000 years ago. This finding is compatible with earlier archaeological finds of human remains near Lake Mungo that date to approximately 40,000 years ago. The idea of the "oldest continuous culture"
18304-407: The sampling process makes use of modern glacial ice cores. Although less rich in O than seawater, the snow that fell on the glacier year by year nevertheless contained O and O in a ratio that depended on the mean annual temperature. Temperature and climate change are cyclical when plotted on a graph of temperature versus time. Temperature coordinates are given in the form of
18447-531: The smaller offshore islands and Tasmania when the land was inundated at the start of the Holocene inter-glacial period , about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people of modern-day Indonesia. Aboriginal Australians have a wide variety of cultural practices and beliefs that some scientists believe make up
18590-649: The sole factor responsible for the variations in climate since they explain neither the long-term cooling trend over the Plio-Pleistocene nor the millennial variations in the Greenland Ice Cores known as Dansgaard-Oeschger events and Heinrich events. Milankovitch pacing seems to best explain glaciation events with periodicity of 100,000, 40,000, and 20,000 years. Such a pattern seems to fit the information on climate change found in oxygen isotope cores. In oxygen isotope ratio analysis, variations in
18733-695: The sources available to him then, concluding that Pelasgians were Greek. In European late antiquity, many Berbers , Copts and Nubians of north Africa converted to various forms of Christianity under Roman rule, although elements of traditional religious beliefs were retained. Following the Arab invasions of North Africa in the 7th century, many Berbers were enslaved or recruited into the army. The majority of Berbers, however, remained nomadic pastoralists who also engaged in trade as far as sub-Saharan Africa. Coptic Egyptians remained in possession of their lands and many preserved their language and Christian religion. By
18876-585: The story of creation known as The Dreamtime . Additionally, traditional healers were also custodians of important Dreaming stories as well as their medical roles (for example the Ngangkari in the Western desert ). Some core structures and themes are shared across the continent with details and additional elements varying between language and cultural groups. For example, in The Dreamtime of most regions,
19019-421: The study of cyclical climate changes. The glacials in the following tables show historical usages, are a simplification of a much more complex cycle of variation in climate and terrain, and are generally no longer used. These names have been abandoned in favour of numeric data because many of the correlations were found to be either inexact or incorrect and more than four major glacials have been recognised since
19162-406: The term Aboriginal has changed over time and place, with the importance of family lineage, self-identification and community acceptance all being of varying importance. The term Indigenous Australians refers to Aboriginal Australians and Torres Strait Islander peoples, and the term is conventionally only used when both groups are included in the topic being addressed, or by self-identification by
19305-861: The term Indigenous peoples or have denied that Indigenous peoples exist in their territory, and have classified minorities who identify as Indigenous in other ways, such as 'hill tribes' in Thailand, 'scheduled tribes' in India, 'national minorities' in China, 'cultural minorities' in the Philippines, 'isolated and alien peoples' in Indonesia, and various other terms. Greek sources of the Classical period acknowledge Indigenous people whom they referred to as " Pelasgians ". Ancient writers saw these people either as
19448-483: The term is necessary, given that a single definition will inevitably be either over- or under-inclusive, making sense in some societies but not in others." However, a number of UN agencies have provided statements of coverage for particular international agreements concerning Indigenous peoples or "working definitions" for particular reports. The International Labour Organization's (ILO) Indigenous and Tribal Peoples Convention, 1989 (ILO Convention No. 169), states that
19591-636: The total world population. This includes at least 5,000 distinct peoples. As there is no universally accepted definition of Indigenous Peoples, their classification as such varies between countries and organizations. In the Americas, Australia and New Zealand, Indigenous status is often applied unproblematically to groups descended from the peoples who lived there prior to European settlement. However, In Asia and Africa, Indigenous status has sometimes been rejected by certain peoples, denied by governments or applied to peoples who may not be considered "Indigenous" in other contexts. The concept of indigenous peoples
19734-764: The two regions and changing ocean circulation patterns, with the onset of glaciation in the Northern Hemisphere occurring around 2.7 million years ago. During the Early Pleistocene (2.58–0.8 Ma), archaic humans of the genus Homo originated in Africa and spread throughout Afro-Eurasia . The end of the Early Pleistocene is marked by the Mid-Pleistocene Transition , with the cyclicity of glacial cycles changing from 41,000-year cycles to asymmetric 100,000-year cycles, making
19877-512: The wider Australian community. Due to the aforementioned disadvantage, Aboriginal Australian communities experience a higher rate of suicide, as compared to non-indigenous communities. These issues stem from a variety of different causes unique to indigenous communities, such as historical trauma, socioeconomic disadvantage, and decreased access to education and health care. Also, this problem largely affects indigenous youth, as many indigenous youth may feel disconnected from their culture. To combat
20020-543: Was a series of glacials and interglacials, stadials and interstadials, mirroring periodic climate changes. The main factor at work in climate cycling is now believed to be Milankovitch cycles . These are periodic variations in regional and planetary solar radiation reaching the Earth caused by several repeating changes in the Earth's motion. The effects of Milankovitch cycles were enhanced by various positive feedbacks related to increases in atmospheric carbon dioxide concentrations and Earth's albedo. Milankovitch cycles cannot be
20163-589: Was motivated by a quest for gold and crusading against Islam. Portugal's first attempt at colonization in what is now Senegal ended in failure. In the 1470s, the Portuguese established a fortified trading post on the West coast of Africa, south of the Akan goldfields. The Portuguese engaged in extensive trade of goods for gold and, in later years, slaves for their sugar plantations in the islands off West Africa and in
20306-412: Was used as a way of linking the experiences, issues, and struggles of groups of colonized people across international borders. At this time 'indigenous people(s)' also began to be used to describe a legal category in Indigenous law created in international and national legislation. The use of the plural 'peoples' recognizes the cultural differences between various Indigenous peoples. The first meeting of
20449-509: Was visited by numerous European and North American whaling, sealing, and trading ships. From the early 19th century, Christian missionaries began to settle New Zealand, eventually converting most of the Māori population. The Māori population declined to around 40% of its pre-contact level during the 19th century; introduced diseases were the major factor. New Zealand became a British Crown colony in 1841. The Aboriginal inhabitants of Australia, after brief encounters with European explorers in
