(Molecular Biology and Evolution (Oxford University Press)) Evolutionary biologists are weighing in based on the increasing power of DNA analyses to explore how changes in diet over eons have caused human adaptations to genes regulating fat metabolism. Nielsen and his colleagues examine data from 101 Bronze Age individuals, and present-day human data from the 1000 Genomes Project. His team analyzed adaptive mutations in the FADS region in Europeans, to determine which mutations might have been targeted by recent natural selection in Europeans and to investigate the physiological effects of the mutations.
