AnthropologistJohn Hawksis interview in the previous upshot of Nature talking about how humans have been undergoing accelerated evolution over the past 40,000 years , mostly due to ethnic fault affecting our genes .
Nature ’s Erica Check Hayden sum up up Hawks ’ position :
[ C]urrent human populations are much more genetically diverse than this hypothesis predicts , so Moyzis and Hawks have close that phylogenesis must have ramped up over the preceding 40,000 years . They chalk some of this acceleration up to human universe growth , which expose the species to more new mutations and created more naked as a jaybird material for pick . But the other cause , Hawks thinks , is civilisation – because although the physiology of humans has not change much in the preceding 40,000 eld , their expansion and migration means that lifestyles , lyric and technologies for sure have .
Although not everyone agrees with Hawks ’s claims , the best translate example of recent human evolution does seem to fit . Genetic mutations that allow adults to digest lactose , a sugar found in milk , have emerged severally in unlike populations in response to the same cultural invention – kine domestication . “ I do n’t see culture as an alternative to genetic science , I see culture as being the explanatory element for these genic changes , ” says Hawks . “ There is no explanation for change without the cistron – environment interaction . ”
