For generations, the story of human origins has been a complex tapestry, pieced together from fossil records and genetic ...

We don’t know where they came from. We don’t know where they went. The unique DNA of an ancient tribe of hunter-gatherers is adding to the confusion surrounding the source of South America’s first ...

It was previously assumed that human evolution followed a straight-line path, whereby separate populations evolved to branch out ... with another population, genetic evidence would have been ...

but that parts of it would occasionally branch off and then later merge back together, we get a much better match with the genetic variation found in human populations today,” says population ...

People coming from the north settled South America. The first hunter-gatherers entered the continent from the region of what ...

Entire regions of trees are disappearing because of invasive pests, disease and a changing climate. The key to their ability ...

By comparing genetic ... the population rebounded. Dr. Hu and his colleagues argue in their paper that this bottleneck is consistent with the fossil record of our human ancestors. Our branch ...

From the beginning of genetics and genomics research, researchers have used “population descriptors” as a shorthand for capturing the complex patterns of human genetic variation across the globe. For ...

Their work will become a foundation of the science of population genetics.
