A peak or dip can be due to local changes at the window end as well as true frequency patterns. (judithcurry.com)
Kaixiong Ye, a postdoctoral research fellow at Keinan's lab, further notes that «our results show a global frequency pattern of the insertion mutation adaptive to vegetarian diet, with highest frequency in Indians who traditionally relied heavily on a plant - based diet.» (sciencedaily.com)
