Same mutation aided evolution in many fish species, Stanford study finds

...t mutations in the same gene in mice cause altered hair patterns. However, in mice similar alterations can also be created by defects in any one of three different genes. "Based on the mouse work you'd predict we would find mutations in any of the three genes in sticklebacks," said Kingsley, who is also a...
