Over the past 150,000 years humans have manifestly been migratory, travelling into vastly different climatic regions of the globe.

If a mother can transmit to her unborn offspring cues that will affect its stature, metabolism and a host of life-history characteristics, she will be at an advantage in fitness terms over a mother who cannot. Paradoxically the reasons for thinking that this has indeed been the case is best found when things go wrong. (more…)
