26 August 2008
Size Of Genitalia Dependent On Need To Fight
Researchers examining male horned beetles from four geographically separated populations say the groups have diverged significantly in the size of the male genitalia, and natural selection operating on the other end of the animal – the fighting horns atop the beetles' heads – seems to be driving it much more quickly than expected...

22 August 2008
