Há 5 dias · The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Há 2 dias · Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes.
Há 21 horas · The evolution of erect limbs in mammals is incomplete—living and fossil monotremes have sprawling limbs. The parasagittal (nonsprawling) limb posture appeared sometime in the late Jurassic or early Cretaceous; it is found in the eutherian Eomaia and the metatherian Sinodelphys , both dated to 125 million years ago.

Há 4 dias · The first vertebrate s, animals with backbones, appeared about 400 million years ago; the first mammal s, less than 200 million years ago. The history of life recorded by fossils presents compelling evidence of evolution. evolution of the horse. Evolution of the horse over the past 55 million years.
Há 5 dias · Large brains have evolved in an assortment of vertebrates (dolphins, parrots, crows) and invertebrates (octopuses). While our study can't determine the exact drivers of brain evolution in all of these species, we have directly tested a key assumption on wild tropical mammals in a relatively non-invasive manner.
