Sociobiology: The Phoenix effect
Kevin R. Foster1
Abstract
A spore-forming bacterium can escape from social collapse and extinction with a single mutation that has a dramatic effect. Here is evidence that a cooperative system can recover from the very brink of destruction.
Where there is society, there are cheaters that threaten to ruin it. The evolution of such selfish behaviour can destroy cooperation, and may even drive a species to extinction1.
- Kevin R. Foster, currently in the Program for Evolutionary Dynamics, Harvard University, will shortly move to the Bauer Center for Genomics Research, Harvard University, Cambridge, Massachusetts 02138, USA.
