Comment Re:ANY stress "alters the DNA" of a fetus. (Score 1) 155
In the wild, other mammals are completely capable of reabsorbing fetuses into their bodies during times of stress, giving evidence that the birth of a litter of young is predicated on environmental factors.
If a mammal uses resource surplus & hardship as a determining factor to give birth, it is not much of a stretch to imagine genetic predisposition is formulated by those factors as well.
