Interaction of just 2 genes governs coloration patterns in mice

on white sand beaches. In the process, the beach mice's coats have become markedly lighter than that of their mainland brethren. "In nature there is a tremendous amount of variation in color patterns among organisms, ranging from leopard spots to z...

What we can learn from the biggest extinction in the history of Earth
...is beginning to look a whole lot like the world we live
in right now," Payne said. "The good news, if there is good news, is that we have not yet released as much carbon into the atmosphere as would be hypothesized for the end-Permian extinction. Whether or not we get there depends largely on future polic...
