The largest ever genetics study of a single population suggests that humans are evolving faster than scientists previously thought.
The Guardian reports:
Scientists reached the conclusion after showing that almost every man alive can trace his origins to one common male ancestor who lived about 250,000 years ago. The discovery that so-called “genetic Adam”, lived about 100,000 years more recently than previously understood suggests that humans must have been genetically diverging at a more rapid rate than thought.
Kári Stefánsson, of the company deCODE Genetics and senior author of the study, said: “It means we have evolved faster than we thought.” …
Previous research also suggested that humans are evolving more quickly now than at any time since the split with the ancestors of modern chimpanzees 6m years ago. The study, by the University of Wisconsin, found that at least 7% of human genes have undergone recent evolution. Some of the changes included the emergence of fair skin and blue eyes in northern Europe, greater resistance to malaria in some African populations and the appearance of a gene that allows lactose to be digested.
