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. It includes brief explanations of the various taxonomic ranks in ...
The evolutionary history of the primates can be traced back 57-90 million years. [1] One of the oldest known primate-like mammal species, Plesiadapis, came from North America; [2] another, Archicebus, came from China. [3] Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene.
Human evolution. The hominoids are descendants of a common ancestor. 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. [1]
Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus. This initial migration was followed by other archaic humans including H. heidelbergensis, which lived around ...
The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1] While the hypothesis has some popularity with the lay ...
Archaic humans. Archaic humans[a] is a broad category denoting all species of the genus Homo that are not Homo sapiens (which are known as modern humans). Among the earliest modern human remains are those from Jebel Irhoud in Morocco (about 315 ka), Florisbad in South Africa (259 ka), [1][2][3][4][5][6], Omo-Kibish I (Omo I) in southern ...
Genetic research indicates arrival of humans in Japan by 37,000 BP. Archeological remains at the Tategahana Paleolithic Site at Lake Nojiri have been dated as early as 47,000 BP. The earliest known remains of Cro-Magnon-like humans are radiocarbon dated to 43,000–46,000 BP, found in Bulgaria, Italy, and Great Britain.
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
