High-carb footprint

摘要

It is easy to assume that the long march of evolution has halted in modern man-that the safe, disease-free lives people now lead mean natural selection no longer operates on much of Homo sapiens. It is an attractive idea. Frances Brodsky of University College, London and her colleagues, however, beg to differ. A paper they have just published in eLife suggests that diet, at least, is still a selective pressure.
