122-543: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in
183-789: A group of bony fish commonly referred to as lobe-finned fish . These vertebrates are characterised by prominent muscular limb buds (lobes) within their fins , which are supported by articulated appendicular skeletons . This is in contrast to the other clade of bony fish, the Actinopterygii , which have only skin -covered bony spines supporting the fins. The tetrapods , a mostly terrestrial superclass of vertebrates, are now recognized as having evolved from sarcopterygian ancestors and are most closely related to lungfishes . Their paired pectoral and pelvic fins evolved into limbs , and their foregut diverticulum eventually evolved into air-breathing lungs . Cladistically , this would make
244-477: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and
305-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in

In accordance with the Convention on International Trade of Endangered Species treaty, the coelacanth was added to Appendix I (threatened with extinction) in 1989. The treaty forbids international trade for commercial purposes and regulates all trade, including sending specimens to museums, through
427-550: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment
488-404: A rectal gland, pituitary gland, pancreas, and spinal cord. To balance osmotic pressure, these fish adopt an efficient mechanism of osmoregulation by retaining urea in their blood. Latimeria chalumnae are an ovoviviparous species, which means that they retain their eggs internally until they hatch. They also have low fecundity due to their long gestation period of around 12 months, though not much
549-608: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek . There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

On December 23, 1938, Hendrik Goosen, the captain of the trawler Nerine , returned to the harbour at East London, South Africa , after a trawl between the Chalumna and Ncera Rivers. As he frequently did, he telephoned his friend, Marjorie Courtenay-Latimer , curator at East London Museum , to see if she wanted to look over the contents of the catch for anything interesting, and told her of

Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and

Latimeria chalumnae exhibit a deep royal blue color with spots used as a camouflage tactic for hunting prey. Similar anatomical adaptations include the abundance of visual cells such as rods to help see when light is limited. This combined with the West Indian Ocean coelacanth's large eyes aid seeing in dark water. Similar to cartilaginous fish, Latimeria chalumnae has
854-548: Is a crossopterygian , one of two extant species of coelacanth , a rare order of vertebrates more closely related to lungfish and tetrapods than to the common ray-finned fishes . The other extant species is the Indonesian coelacanth ( L. menadoensis ). The West Indian Ocean coelacanth was historically known by fishermen around the Comoro Islands (where it is known as gombessa ), Madagascar, and Mozambique in
915-570: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected
1037-549: Is allocated to the genus Latimeria , which it shares with one other species, the Indonesian coelacanth ( Latimeria menadoensis ). From September 1997-July 1998, two coelacanth fish were discovered off the coast of Manado Tua Island, Sulawesi, Indonesia, different from the Latimeria chalumnae discovered near the Comores. The Indonesian coelacanth is identifiable by its brownish grey color. The genome of Latimeria chalumnae
1098-666: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to
1159-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in

L. chalumnae are usually found between 180–210 m (590–690 ft) of depth, but are sometimes found as deep as 243 m (797 ft) and as shallow as 54 metres (177 ft). L. chalumnae tend to reside in underwater caves, which are most common at these depths. This may limit their maximum depth range, along with lack of prey. They are known to spend
1281-629: Is made possible due to the coelacanth's ability to move both its upper and lower jaw, which is a unique trait in extant vertebrates that have bone skeletons. L. chalumnae is widely but very sparsely distributed around the rim of the western Indian Ocean , from South Africa northward along the East African coast, especially the Tanga Region of Tanzania to Kenya, the Comoros, and Madagascar, seemingly occurring in small colonies.

Early lobe-finned fishes are bony fish with fleshy, lobed, paired fins, which are joined to the body by a single bone. The fins of lobe-finned fishes differ from those of all other fish in that each is borne on a fleshy, lobelike, scaly stalk extending from
1464-759: The Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as the Pella curse tablet , as Hatzopoulos and other scholars note. Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

Failing to find a description of the creature in any of her books, Courtenay-Latimer attempted to contact her friend, Professor J. L. B. Smith , but he was away for Christmas. Unable to preserve the fish, she reluctantly sent it to a taxidermist . When Smith returned, he immediately recognized it as a coelacanth, known to science only from fossils. Smith named

Over time, researchers have identified 121 species spread across 47 genera. Some species are well-documented in their evolutionary placement, while others are harder to track.The greatest boom in actinistian diversity happened during the Early Triassic, just after the Great Dying. Coelacanths of

Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

In the early–middle Devonian (416–385 Ma), while the predatory placoderms dominated
2074-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has

For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in

The scales of sarcopterygians are true scaloids, consisting of lamellar bone surrounded by layers of vascular bone, cosmine (similar to dentin ), and external keratin . The physical structure of tetrapodomorphs, fish bearing resemblance to tetrapods, provides valuable insights into the evolutionary shift from aquatic to terrestrial existence. Pectoral and pelvic fins have articulations resembling those of tetrapod limbs. The first tetrapod land vertebrates, basal amphibian organisms, possessed legs derived from these fins. Sarcopterygians also possess two dorsal fins with separate bases, as opposed to

One standard formulation for the dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West

The fin-limbs found in lobe-finned fishes like the coelacanths display a strong resemblance to the presumed ancestral form of tetrapod limbs. Lobe-finned fishes seemingly underwent two distinct evolutionary paths, leading to their classification into two subclasses: the Rhipidistia (comprising

At the time it was believed to be a new species and placed in a new genus as well, Malania , named in honour of the Prime Minister of South Africa at the time, Daniel François Malan , without whose help the specimen would not have been preserved with its muscles and internal organs more or less intact. It has since been accepted as Latimeria chalumnae . The West Indian Ocean coelacanth ( Latimeria chalumnae )

Some of their known prey species are fish that include: Amioides polyacanthus , Beryx splendens , Lucigadus ori and Brotula multibarbata . Their intracranial joint and associated basicranial muscle likely play an important but unresolved role in feeding.

The Rhipidistians, whose ancestors probably lived in the oceans near river mouths and estuaries , left the marine world and migrated into freshwater habitats. They then split into two major groups: the lungfish and the tetrapodomorphs , and both of them evolved their swim bladders into air-breathing lungs. Lungfish radiated into their greatest diversity during

The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with the Dorians. The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from

Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at the time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to

Non-tetrapod sarcopterygians continued until towards
