Verifying our model, we found more ancestry of Southern Chinese from Hunan in Africans relative to other East Asian groups examined. The Neanderthal genome project has clarified our understanding of modern human origins and suggests that low levels of interbreeding occurred between Neanderthals and modern humans early during the expansion of modern humans out of Africa.

There are major disagreements in the field about whether human evolution is more like a branching tree or a crooked stick, depending partly on how many species one recognizes. 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, which includes the great apes.

Steve builds a case for how humans appeared as a distinct group about 150,000 to 200,000 years ago based on genetic variation we see in people today. In an article published in Nature Ecology & Evolution, an international team of researchers analyses the . Innovative educational programs meet the critical need for expanding public knowledge of scientific research and evolution. 2014). Here we test the replacement theory in two peripheral areas far from Africa by examining the ancestry of early modern Australians and Central Europeans. Most scientists believe that primates and humans all share a recent common ancestor at about 80 million years ago.
