Age and Origin of the Human Species

British paleoanthropologist Chris Stringer has taken a leading role in many of the earliest human origins debates. Educated at the University College London and Bristol University, Sringer is one of the leading proponents of the "Out of Africa" model of Homo sapiens diffusion. Stringer is currently working in the Paleontology Department at the British Natural History Museum.

, found at site in Ethiopia, lived about 160,000 years ago. It is the oldest known anatomically modern human and classified as an subspecies. Fossils of modern humans were found in cave in and have been dated to 100,000 years ago. However these humans seem to have either gone extinct or retreated back to Africa 70,000 to 80,000 years ago, possibly replaced by south bound Neanderthals escaping the colder regions of ice age Europe.[citation needed] Hua Liu & al. analyzing autosomal microsatellite markers dates to c. 56,000±5,700 years ago evidence. The fossil of early modern human from dated at 80,000–100,000 Liu interpret as isolated early offshoot that retracted back to Africa.

Recent single-origin hypothesis - ScienceDaily

was one of the first to propose of living organisms, and among the first to suggest that all humans had in common ancestors who lived in Africa. In the he speculated that humans had descended from apes which still had small brains but walked upright, freeing their hands for use which favoured intelligence, and that these apes were African:

Well written by a respected physicist who uses good prose and metaphor to explain complexity and it's implication on how we view the universe.

Multiregional origin of modern humans - Wikipedia

For example, Chinese Homo erectus specimens had the same flat faces, with prominent cheekbones, as modern Oriental populations. Javanese Homo erectus had robustly built cheekbones and faces that jutted out from the braincase, characteristics found in modern Australian Aborigines. No definite representatives of Homo erectus have yet been discovered in Europe. Here, the fossil record does not extend back as far as those of Africa and eastern Asia, although a possible Homo erectus jawbone more than a million years old was recently excavated in Georgia.

The divergence of within Africa dates to this time: The of Southern Africa and the of East Africa branched off between 260,000 and 350,000 years ago and have remained relatively genetically isolated since then. The San people are a subgroup of the peoples.

Modern proponents of this approach focus on a recent and restricted origin for modern Homo sapiens. This was dubbed the "Garden of Eden" or "Noah's Ark" model by the US anthropologist William Howells in 1976 because of the idea that all modern human variation had a localized origin from one centre. Howells did not specify the centre of origin, but research since 1976 points to Africa as especially important in modern human origins.

Evolution: Out of Africa and the Eve Hypothesis

The opposing view is that Homo sapiens had a restricted origin in time and space. This is an old idea. Early in the 20th century, workers such as Marcellin Boule (France) and Arthur Keith (UK) believed that the lineage of Homo sapiens was very ancient, having developed in parallel with that of Homo erectus and the Neanderthals. However, much of the fossil evidence used to support their ideas has been re-evaluated, and few workers now accept the idea of a very ancient and separate origin for modern Homo sapiens.

Recent African Origin Of Modern Humans - Wikipedia

"Recent African origin," or , refers to the migration of () out of Africa after 200,000 years ago. There seem to have been at least two dispersals of populations of out of Africa, and even more dispersals have been proposed.
