A recent study published in Open Biology reports that exposure to intense light almost instantly provokes courtship behavior in male fruit flies (Drosophila). Surprisingly, the researchers observed both male-male and male-female ...
The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn't, however, clarify why older fathers pass ...
