Giving birth has never been easy. Nature seems to have decided that whoever wants to procreate should put in an effort. Sometimes the process of birth, the physical separation from offspring, is so difficult that a mother needs a helping hand. And humans are not alone in this trait. An interdisciplinary research team at the Weizmann Institute has discovered that "midwives" also play a role in the microscopic world of amoebas. It is this collaborative birth process, reported in the March 21, 2001 issue of Nature, that has given amoebas an evolutionary edge.
