 | 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 |
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.

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.

 | 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 |
 | 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 |
 | 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 |
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.
