A chimp-pig hybrid origin for humans?

(Phys.org) —These days, getting a Ph.D. is probably the last thing you want to do if you are out to revolutionize the world. If, however, what you propose is an idea, rather than a technology, it can still be a valuable ...

Darwin descended from Cro-Magnon man: scientists

The father of evolution Charles Darwin was a direct descendant of the Cro-Magnon people, whose entry into Europe 30,000 years ago heralded the demise of Neanderthals, scientists revealed in Australia Thursday.

The peopling of the Americas: Genetic ancestry influences health

At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from. Did our ancestors come from Europe or Asia? As curious as we are about our ancestors, for practical ...

Did modern humans eat Neanderthals?

Modern humans may have eaten Neanderthals, scientists report in the Journal of Anthropological Sciences this month.

Grassy beginning for earliest Homo

In 2013, an ASU research team found the oldest known evidence of our own genus, Homo, at Ledi-Geraru in the lower Awash Valley of Ethiopia. A jawbone with teeth was dated to 2.8 million years ago, about 400,000 years earlier ...

Human evolution

Human evolution, or anthropogenesis, is the part of biological evolution concerning the emergence of Homo sapiens as a distinct species from other hominins, great apes and placental mammals. It is the subject of a broad scientific inquiry that seeks to understand and describe how this change occurred. The study of human evolution encompasses many scientific disciplines, most notably physical anthropology, primatology, archaeology, linguistics and genetics.

The term "human", in the context of human evolution, refers to the genus Homo, but studies of human evolution usually include other hominins, such as the Australopithecines. The Homo genus diverged from the Australopithecines about 2 million years ago in Africa. Scientists have estimated that humans branched off from their common ancestor with chimpanzees—the only other living homininis—about 5–7 million years ago. Several species of Homo evolved that are now extinct. These include Homo erectus, which inhabited Asia, and Homo neanderthalensis, which inhabited Europe.

Archaic Homo sapiens evolved between 400,000 and 250,000 years ago. The dominant view among scientists is the recent African origin of modern humans (RAO) that H. sapiens evolved in Africa and spread across the globe, replacing populations of H. erectus and H. neanderthalensis. Scientists supporting the alternative hypothesis on the multiregional evolution (ME) view modern humans as having evolved as a single, widespread population from existing Homo species, particularly H. erectus. The fossil evidence is insufficient to resolve this vigorous debate,. Studies of haplogroups in Y-chromosomal DNA and mitochondrial DNA have largely supported a recent African origin, while some researchers argue that evidence from nuclear genes supports a multiregional origin.
