The origin of the reptiles lies about 320–310 million years ago, in the swamps of the late Carboniferous period, when the first reptiles evolved from advanced labyrinthodonts. [2] The oldest known animal that may have been an amniote , a reptile rather than an amphibian , is Casineria [ 3 ] [ 4 ] (though it has also been argued to be a ...
Evolve is a 2008 documentary television series on the History Channel. Each episode attempts to explain the evolutionary origins of a particular trait of living creatures: for example, Tyrannosaurus rex 's 13-inch teeth, the gecko 's " Velcro -like" toe pads, and the bald eagle 's "telescopic" vision capable of spotting a hare a mile away.
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.
Similarly, climate warming that occurred millions of years ago helped reptiles evolve faster, diversify, and conquer the world, says a new study. Researchers have long believed the extinction of ...

The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [73] - although humans may have four or five. [79] The main hominid molar cusp evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost. Prosimians ...
The discovery of Skiphosoura and another species called Dearc sgiathanach, which lived roughly 170 million years ago in Scotland, have helped clarify key events in pterosaur evolution.
The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes. [1] Tetrapods (under the apomorphy-based definition used on this page) are categorized as animals in the biological superclass Tetrapoda, which includes all living and extinct amphibians, reptiles, birds, and mammals.
