[phys.org] Milk consumption increased ancient human body size, finds study.


A new study led by Western biological anthropology professor Jay Stock, suggests that milk consumption in some regions between 7,000 and 2,000 years ago led to an increase in human body mass and stature. This ran counter to trends in body size experienced elsewhere in the world. This size increase is found in regions where there was evolution for higher frequencies of genes that allow humans to produce enzymes to digest milk into adulthood—called lactase persistence. The study, involving a team of 16 researchers, compared the stature and body mass of 3,507 skeletons from 366 different archaeological sites, ranging across 25,000 years, creating a large comparative data set to examine human body variation over time and geographic location. The study was published today in PNAS.
