Females of some species might obtain additional resources from semen, apart from sperm, and could have evolved to seek out these bonuses from having sex, according to a new theory by UNSW scientists.
I don’t see the point of doing research if nobody knows about it. And it’s pretty hard to talk about sperm without cracking a joke or two, writes Angela Crean.
UNSW scientists have discovered a new form of non-genetic inheritance, showing for the first time that offspring can resemble a mother’s previous sexual partner – in flies at least.
