in the founding population a century ago, but it could have been much larger. It would be as if all of the people in the United States were descended from the Pilgrims who came here in 1620." Instead of fighting, Tsutsui explained, each new ge...

Mole-rat Methuselahs push evolutionary theory of aging
...e, Sherman adds, noting that mole-rat queens, like queens
in honeybees and termites, are considerably larger than workers in their colonies. Fecundity is important because if old individuals can make disproportionate reproductive contributions, there will be strong selection to postpone senescence. While n...

Desert bees hedge their bets, wait for the wet

and no workers. "Everyone is a queen, everyone is a worker. They are the soccer moms of the insect world," he says. His research shows that rain triggers the bees' emergence from the larval state into pupae, and then finally into adult desert bees....
