Scientists used a technology designed for the purposes of human forensics, to provide the first genetically documented case of infanticide in brown bears, following the murder of a female and her two cubs in Trentino, the ...
A study of the colour patterns among wild flowers in a mountain valley has yielded a clue about how nature controls fundamental evolutionary change in all species.
We've all heard Darwin's theory described as favoring the fittest, but new research from Michigan State University shows that, at least in small populations, it's O.K. to not be the best.
