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.
Researchers report that some stickleback fish fathers can have long-term effects on the behavior of their offspring: The most attentive fish dads cause their offspring to behave in a way that makes them less susceptible to ...
Have you ever wondered why we give birth to live young rather than lay eggs? Scientists have pondered this for a long time and answers have come from an unlikely source: some of Australia's lizards and snakes!
Male stickleback fish that protect their young have bigger brains than counterparts that don't care for offspring, finds a new University of British Columbia study.
