- pervycreeper 11y agoIt's not clear to me why environmental pressure would increase weaning age, or, for that matter, why hunting pressure would decrease it. Anyone care to explain these suppositions?
- throwaway2048 11y agoI would guess that mothers dying to hunters would be the decrease in average weening age, and harsh enviroment leading to poor milk production would be the cause of an increase.
