Stone tools found at the Shangchen site in China and dated to 2.12 million years ago are considered the earliest known evidence of hominins outside Africa, surpassing Dmanisi hominins found in Georgia by 300,000 years, although whether these hominins were an early species in the genus Homo or another hominin species is unknown.

Haikouichthys, a jawless fish, is popularized as one of the earliest fishes and probably a basal chordate or a basal craniate. [72] Ferns first appear in the fossil record about 360 million years ago in the late Devonian period. [73] Synapsids such as Dimetrodon were the largest terrestrial vertebrates in the Permian period, 299 to 251 million ...
There are numerous difficulties in detecting and understanding the ancient diet of human ancestors. The Paleolithic begins around 2.6 million years ago and ends only around 12,000 years ago with the onset of the Holocene and Neolithic. The enormous time scale, variable environments inhabited by human ancestors and issues with preservation ...
Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The eggs date back more than 80 million years ago, making it a part of the Late Cretaceous period (66 to 100.5 million years ago).
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
The Virgin Galactic 03 space trip included some fossilized remains of ancient human relatives Australopithecus sebida and Homo naledi.
