The first solid evidence of natural selection in recent human populations was found in blood.
In addition to blood type, researchers have investigated the evolution of blood disorders and abnormalities.
While the distribution of blood types and abnormalities was the first evolutionary pattern identified among recent human populations, perhaps the most famous is people’s ability to digest milk beyond infancy.
Much of the human diversity we see around us today arose very recently. More than 90 percent of the heritage of every living human comes from sub-Saharan Africa sometime around 100,000 years ago. Fifteen years ago, many geneticists saw this recent common ancestry as evidence that human evolution had mostly drawn to a close.

New evidence of how the human genome has changed over the last several thousand years points to a series of massive critical evolutionary changes, setting some aspects of our biology clearly apart from that of our forebears. And we are no doubt continuing to evolve today.
