Shawn let's try to find a common language here so we know what we are talking about. Do you really think these people are 'scientists'? They are guessing, making stuff up, making arbitrary claims, building on that more arbitrary claims. They have no idea if these bones they are finding have any relationship at all to the man at the mall. This is worse than religion because they are pretending to be something they are not. They are just telling pretty stories to get their grant money, may their names be forgotten by posterity.
I'm still looking for the 50000 bc version of Shakespeare.
Overview of homo sapiens from wikipedia
Human evolution, or anthropogenesis, is the origin and evolution of Homo sapiens as a distinct species from other hominids, great apes and placental mammals. The study of human evolution encompasses many scientific disciplines, including physical anthropology, primatology, archaeology, linguistics and genetics.[1]
The term "human" in the context of human evolution refers to the genus Homo, but studies of human evolution usually include other hominids, such as the Australopithecines, from which the genus Homo had diverged by about 2.3 to 2.4 million years ago in Africa.[2][3]
Scientists have estimated that humans branched off from their common ancestor with chimpanzees about 57 million years ago. Several species and subspecies of Homo
evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo sapiens neanderthalensis, which inhabited Europe.
Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.The dominant view among scientists concerning the origin of anatomically modern humans is the "Out of Africa" or recent African origin hypothesis,[4][5][6][7] which argues that Homo sapiens arose in Africa and migrated out of the continent around 50,000 to 100,000 years ago, replacing populations of Homo erectus in Asia and Homo neanderthalensis in Europe.
Scientists supporting the alternative multiregional hypothesis argue that Homo sapiens evolved as geographically separate but interbreeding populations stemming from a worldwide migration of Homo erectus out of Africa nearly 2.5 million years ago.
Archaic Homo sapiens
Archaic Homo sapiens is
a loosely defined term used to describe
a number of varieties of Homo,
as opposed to anatomically modern humans (Homo sapiens sapiens), in the period beginning 500,000 years ago. The term is typically taken to include Homo heidelbergensis, Homo rhodesiensis, Homo neanderthalensis and sometimes Homo antecessor.[1]
Modern humans
are believed to have evolved from archaic Homo sapiens, who in turn evolved from Homo erectus. Varieties of archaic Homo sapiens (also "Archaics" for short[dubious discuss])
are included under the binomial name "Homo sapiens"
because their brain size is very similar to that of modern humans. Archaic Homo sapiens had a brain size averaging 1200 to 1400 cubic centimeters, which overlaps with the range of modern humans. Archaics are distinguished from anatomically modern humans by having a thick skull, prominent brow ridges and the lack of a prominent chin.[1][2]
Anatomically modern humans appear
from about 200,000 years ago and after 70,000 years ago
gradually marginalize the "archaic" varieties. Non-modern varieties of Homo are certain to have survived until after 30,000 years ago, and
perhaps until as recent as 10,000 years ago. Which of these, if any, are included under the term "archaic Homo sapiens"
is a matter of definition and varies among authors.The category archaic Homo sapiens
is disputed.[1]
There is no single agreed upon definition of archaic Homo sapiens.
According to one definition, Homo sapiens is a single species comprising several subspecies that include the archaics and modern humans. Under this definition, modern humans are referred to as Homo sapiens sapiens and Archaics are also designated with the prefix "Homo sapiens". For example, the Neanderthals are Homo sapiens neanderthalensis, and Homo heidelbergensis is Homo sapiens heidelbergensis.
Other taxonomists prefer not to consider archaics and modern humans as a single species but as several different species. In this case the standard taxonomy is used, ie Homo rhodesiensis, or Homo neanderthalensis[1].
The dividing lines that separate modern humans from archaic Homo sapiens and archaics from Homo erectus
are blurry. The earliest known fossils of anatomically modern humans such as the Omo remains from 195kya, Homo sapiens idaltu from 160kya, and Qafzeh remains from 90kya are recognizably modern humans.
However, these early modern humans do exhibit a mix of some archaic traits, such as moderate, but not prominent, brow ridges. The brain size of Archaic Homo sapiens expanded significantly from 900 cubic centimeters in erectus to 1300 cubic centimeters. Since the emergence of archaics, brain size has remained stable up until the present.
Origin of language
Main article: Origin of language
Robin Dunbar
has argued that Archaic Homo sapiens were the first to use language. Based on his analysis of the relationship between brain size and hominid group size, he concluded that because Archaic Homo sapiens had large brains, they must have lived in groups of over 120 individuals. Dunbar argues that it was not possible for Hominids to live in such large groups without using language, otherwise there could be no group cohesion and the group would disintegrate. By comparison, chimpanzees live in smaller groups of up to 50 individuals.[4][5]
