Humans are evolving more rapidly than previously thought, according to the largest ever genetics study of a single population.



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



...



The study also shows that the most recent common male ancestor was alive at around the same time as “mitochondrial Eve” - the last woman to whom all females alive today can trace their mitochondrial DNA.



...



The study, published in Nature Genetics, put the new age for genetic Adam at between 174,000 and 321,000 years ago. Genetic Eve is thought to have walked the Earth around 200,000 years ago: well within the new error margin for Adam.
