Cheating -- and getting away with it
Date:1/11/2013

facultative cheaters, cheating only under favorable conditions, and not obligate cheaters, forced to cheat no matter what.

The overall robustness of knockout mutant CheaterB deepens the mystery. "No measurable laboratory trait revealed an Achilles heel," Strassmann says, "but that doesn't mean there isn't one in natural environments. Otherwise, why would a naturally occurring mutation that duplicated the knockout not take over amobae populations?"
