Unlike humans, who need on average 20 years between generations, these small creatures only need about 20 minutes to foster offspring. This means that the bacterium can evolve some 500,000 times faster than us. This rapid rate offers the prime opportunity to explore some of the deeper mysteries and perhaps even offer mechanisms to best predict when evolution might happen to us.
An article published in Scientific American this week demystified a commonly held colloquialism -- Rachel and Ross knew it, Monica and Chandler certainly knew it: men and women can't be "just Friends." Nomenclature aside, men carry certain chromosomal differences from women. It's why our balls drop and our voices get deeper. It's not why we get to be douchebags and blame Darwin for our douchebaggery.
