Microscopic ocean plankton mimic card also known as the Black Queen Sleight of hand is a trait that belongs mainly to humans. Or so scientists thought. Studies of common, microscopic ocean plankton named Prochlorococcus show that humans aren't the only ones who can play a mean game of cards. Their method lurks in the Black Queen Hypothesis, as it's called, after the Queen of Spades in the card game Hearts. Scientists Jeffrey Morris and Richard Lenski of Michigan State...

By Danielle J. Whittaker, BEACON Center for the Study of Evolution in Action, Michigan State University Researchers are decoding the patterns that connect different types of nerve cells Though the brain may seem impossibly complex, it can be understood as a network, much like computer chips or the Internet. A new analysis in the journal PLoS ONE has described the workings of a worm's nervous system as patterns involving the connections among nerve cells with different functions. Unlike the...

When it comes to producing more offspring, larger female hyenas outdo their smaller counterparts. A new study by Michigan State University researchers, which appears in Proceedings of the Royal Society, revealed this as well as defined a new way to measure spotted hyenas' size. "This is the first study of its kind that provides an estimate of lifetime selection on a large carnivore," said MSU graduate student Eli Swanson, who published the paper with MSU faculty members Ian Dworkin and Kay...

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...
