NSF-supported researchers use digital evolution techniques to examine theories about the evolution of altruism One of the major questions in evolutionary biology is how altruism, or the act of helping another individual at your own expense, evolved. At first glance, "survival of the fittest" may seem to be best achieved by selfish individuals. However, altruistic behavior occurs in many species, and if it were not adaptive, we would expect it to disappear through the process of natural...

Using digital evolution techniques that give scientists the ability to watch evolution in action, Michigan State University researchers have shed new light on what it is that makes species altruistic. Defined as the ability to sacrifice yourself for the sake of others, altruism has been a bit of a genetic mystery. Understanding why altruism evolves is one of the fundamental challenges in evolutionary theory. However, a paper published online in the journal Proceedings of the Royal Society by...
