Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and ...

The Amazon molly is an evolutionary enigma: an all-female fish that reproduces by cloning itself. Because it doesn’t mix its DNA with a mate’s, Darwinian logic holds that harmful mutations should pile ...
