Humans are evolving slower than thought

Humans might be evolving slower than scientists had thought, according to a new analysis of the genomes of two families, but there is a huge variance between people.

The researchers, reporting their findings June 12 in the journal Nature Genetics, based their measurement of evolution speed on the number of new mutations that occur during one generation in each of the families. A slower mutation rate means we probably separated from chimpanzees evolutionarily longer ago than previously thought, the researchers say, adding that the finding may have medical implications, if some groups of people are more mutation-prone than others.
