Altruism in bacteria: Colonies divide the work

Bacteria found in soil specialize in the colony by division of labor. Some of the bacteria produce antibiotics, even when it comes at the expense of their individual reproduction success, to defend their colony against competitors.

Programmed cell death

Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. In contrast to necrosis, which is a form of cell-death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process which generally confers advantage during an organism's life-cycle. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.
