the results of this test are when you compare humans and birds," said Dr. Chris Sturdy, a psychology professor at the University of Alberta. "Humans and rats are weak by any standard, and they're just awful when you compare them to the songbirds." Fo...
Rice wins $5m to probe social evolution using latest genetic tools
...mann have shown how groups of amoebae that contain dissimilar
genes compete within the colony to gain a reproductive advantage. "The genetic tools and simplicity of sociality in social amoebae make it easier to study the processes of cooperation and conflict that also operate in other organisms," said Strassman...
