In-group Altruism And Hostility Toward Outsiders Evolved Together (10/29/2007)

SFI researcher Samuel Bowles and colleague Jung-Kyoo Choi of Kyungpook National University in South Korea suggest that the altruistic and warlike aspects of human nature may have a common origin. ...> Full Article

Researchers posit new ideas about human migration from Asia to Americas (10/26/2007)

Questions about human migration from Asia to the Americas have perplexed anthropologists for decades, but as scenarios about the peopling of the New World come and go, the big questions have remained. Do the ancestors of Native Americans derive from only a small number of "founders" who trekked to the Americas via the Bering land bridge? How did their migration to the New World proceed? What, if anything, did the climate have to do with their migration? And what took them so long? ...> Full Article

Neandertals, Humans Share Key Changes To 'Language Gene' (10/21/2007)

A new study reveals that adaptive changes in a human gene involved in speech and language were shared by our closest extinct relatives, the Neandertals. The finding reveals that the human form of the gene arose much earlier than scientists had estimated previously. It also raises the possibility that Neandertals possessed some of the prerequisites for language. ...> Full Article

Spread Of Endogenous Retrovirus K Is Similar In The DNA Of Humans And Rhesus Monkeys (10/11/2007)

According to paleontologic and molecular studies, the chimpanzee (Pan troglodytes) is the closer relative to the humans (Homo sapiens) and that both lineages had a common ancestor at 5 to 7 million years ago. ...> Full Article

Which Came First, the Chicken Genome or the Egg Genome? (10/9/2007)

Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first? And which are the duplicates? ...> Full Article

Synchrotron Light to Reveal How Early Homo sapiens and Neanderthals Grew Up (10/9/2007)

An team of researchers is working together in Grenoble (France) to study the teeth of some famous fossil children, which will reveal if different species of humans experienced similar timings of maturation and reproduction. ...> Full Article

Researcher Shed Light On Diet Of Early Human Ancestors (5/3/2007)

Eight years ago, the field of anthropology was rocked by isotopic evidence that suggested one-third of the diet of early human ancestors consisted of grasses and sedges, or the tissue of animals that ate such plants. The news puzzled scientists, who were unable to reconcile the results with what they knew about the teeth of human ancestors who lived more than 2 million years ago. ...> Full Article

Human-Chimp Gene Study Upsets Long-Held View (4/19/2007)

Put a human and a chimpanzee side by side, and it seems obvious which lineage has changed the most since the two diverged from a common ancestor millions of years ago. Such apparent physical differences, along with human speech, language and brainpower, have led many people to believe that natural selection has acted in a positive manner on more genes in humans than in chimps. ...> Full Article
