摘要

E "kamikaze" caste, born with a self-destruct button that causes the insect to explode upon colony attack, killing itself and covering the invading animals in toxic chemicals. Remarkably, differences in the behavior and morphology of insect castes are usually generated through differences in the expression of identical sets of genes. (There are a few cases of genetically determined castes, but this is the exception, not the rule.) We are now entering a new era of research into eusocial insects. For the first time, scientists are investigating the offspring of its own? We now understand that worker behavior can evolve because workers still pass on their genes through the related offspring they help raise. This has allowed eusociality to evolve multiple times throughout biological history: 10 times in the Hymenoptera (the ants, bees, and wasps), and an additional 22 times in termites, aphids, thrips, and snapping shrimps. It has even appeared a couple of times in mammals, with independent origins in two species of mole rat. (See "Underground Supermodels," The Scientist, June 2012.).
