Early anthropology was divided between proponents of unilinealism, who argued that all societies passed through a single evolutionary process, from the most primitive to the most advanced, and various forms of non-lineal theorists, who tended to subscribe to ideas such as diffusionism.

According to the fossil record, Lissamphibia, which includes all modern amphibians and is the only surviving lineage, may have branched off from the extinct groups Temnospondyli and Lepospondyli at some period between the Late Carboniferous and the Early Triassic.

There are large gaps in the fossil record but the discovery of a proto-frog from the Early Permian in Texas in 2008 provided a missing link with many of the characteristics of modern frogs.

Although the fossils of several older proto-frogs with primitive characteristics are known, the oldest " true frog " is Prosalirus bitis, from the Early Jurassic Kayenta Formation of Arizona.

Artists of the Early Renaissance and the High Renaissance developed their characteristic styles from the observation of nature and the formulation of a pictorial science.

Breton is a Brythonic language, descended from the Celtic British language brought from Great Britain to Armorica by migrating Britons during the Early Middle Ages.

In the Triassic period some groups of archosaurs ( a group that includes the ancestors of crocodiles ) developed bipedalism ; among their descendants the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds ; the birds descended from one group of exclusively bipedal dinosaurs.

The Jurassic is a geologic period and system that extends from Ma ( million years ago ) to Ma ; that is, from the end of the Triassic to the beginning of the Cretaceous.

This created more coastlines and shifted the continental climate from dry to humid, and many of the arid deserts of the Triassic were replaced by lush rainforests.

For example geochemical signatures from rocks may help to discover when life first arose on Earth, and analyses of carbon isotope ratios may help to identify climate changes and even to explain major transitions such as the Permian – Triassic extinction event .< ref name =" Twitchett "> A relatively recent discipline, molecular phylogenetics, often helps by using comparisons of different modern organisms ' DNA and RNA to re-construct evolutionary " family trees "; it has also been used to estimate the dates of important evolutionary developments, although this approach is controversial because of doubts about the reliability of the " molecular clock ".

It would take well into the Triassic for life to recover from this catastrophe.

They existed from the late Triassic to the end of the Cretaceous Period ( 210 to 65. 5 million years ago ).

The Triassic is a geologic period and system that extends from about 250 to 200 Ma ( million years ago ).

Ancestors of Volvox transitioned from single cells to form multicellular colonies at least, during the Triassic period.

The demise of the dinosaurs at the end of the Cretaceous promoted expansion of the mammals, which had evolved from the therapsids, a group of synapsid reptiles, during the late Triassic Period.

The first proto-turtles are believed to have existed in the late Triassic Period of the Mesozoic era, about 220 million years ago, and their shell, which has remained a remarkably stable body plan, is thought to have evolved from bony extensions of their backbones and broad ribs that expanded and grew together to form a complete shell that offered protection at every stage of its evolution, even when the bony component of the shell was not complete.

This is supported by fossils of the freshwater Odontochelys semitestacea or " half-shelled turtle with teeth ", from the late Triassic, which have been found near Guangling in southwest China.

Their fossils may be found in small numbers in rocks from the Triassic period, and became common in the Jurassic and later periods.

Upper Triassic breccia from York County, Pennsylvania.

The first amniotes are known from the early part of the Late Carboniferous, and during the Triassic counted among their number the earliest mammals, turtles, crocodiles ( lizards and birds appeared in the Jurassic, and snakes in the Cretaceous ), and a fourth Carboniferous group, the baphetids, which are thought to be related to temnospondyls, left no modern survivors.

The first true dipterans known are from the Middle Triassic, and they became widespread during the Middle and Late Triassic.

The Treatise on Invertebrate Paleontology ( Part L, 1957 ) divides the Ammonoidea, regarded simply as an order, into eight suborders, the Anarcestina, Clymeniina, Goniatitina, and Prolecanitina from the Paleozoic ; the Ceratitina from the Triassic ; and the Ammonitina, Lytoceratina, and Phylloceratina from the Jurassic and Cretaceous.

The earliest that Cypriniformes might have diverged from Characiphysi ( Characiformes and relatives ) is thought to be about the Early Triassic, about 250 million years ago ( mya ).
