When it comes to getting out of a tricky situation, we humans have an evolutionary edge over other primates. Take, as a dramatic example, the Apollo 13 voyage in which engineers, against all odds, improvised a chemical filter ...

A team of researchers affiliated with several institutions in Australia has proposed that some neurological disorders might have their roots in evolutionary mistakes. In their paper published in the journal Nature Neuroscience, ...
Sand-dwelling and rock-dwelling cichlids living in East Africa's Lake Malawi share a nearly identical genome, but have very different personalities. The territorial rock-dwellers live in communities where social interactions ...
