Humans, and even pet dogs, are more than just products of genes. As Russell Bonduriansky writes, environments play a vital role in shaping us – even before conception.
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.
Imagine how easy life would be if you could produce offspring without a mate, write Angela Crean, Nathan Burke and Russell Bonduriansky.
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.
