Those of us who want to learn about our ancestors — who they were, where they came from and how they mingled (or didn't) with others around them — often turn to historical records or elderly family members for answers. But a new study by researchers at the Stanford University School of Medicine and the University of Miami Miller School of Medicine indicates that the answers can also be found within our own genes. The researchers compared patterns of genetic variation found in...

Nearby Chimpanzee Populations Show Greater Genetic Diversity Than Distant Human Populations

Chimpanzee populations living in relatively close proximity are substantially more different genetically than humans living on different continents, according to a study published March 2 in PLoS Genetics. The study suggests that genomics can provide a valuable new tool for use in chimpanzee conservation, with the potential to identify the population of origin of an individual chimpanzee or the provenance of a sample of bush meat. Common chimpanzees in equatorial Africa have long been...

Researchers at Brown University and Stanford University have pieced together ancient human migration in North and South America. Writing in the American Journal of Physical Anthropology, the authors find that technology spread more slowly in the Americas than in Eurasia. Population groups in the Americas have less frequent exchanges than groups that fanned out over  Europe and Asia. How modern-day humans dispersed on the planet and the pace of civilization-changing technologies that...

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 purposes, we need to think about the ancestry of our genes, according to Cecil Lewis, assistant professor of anthropology at the University of Oklahoma.  Lewis says our genetic ancestry influences the genetic traits that predispose us to risk or resistance...

ENVIRONMENTAL factors can affect DNA over a person's lifetime in ways that may be inherited, new research has shown. The findings add to the growing evidence that diet and lifestyle have health affects which may pass down generations. They also suggest a possible connection with the ailments of ageing, such as heart disease and cancer. Scientists know that while the genetic code is fixed, it can be affected by chemical "switches" controlled by environmental factors. They can turn...
