““A distinct germ line maintains continuity from generation to generation, regardless of what happens to the rest of the body. In this way, a body can be seen as a temporary structure that enables the germ line to fulfill its fundamental task of reproduction in each generation. Evolutionary biology therefore has a convincing answer to that age-old conundrum: "Which came first, the chicken or the egg?" The egg, of course, came first. Chickens, like people, evolved so that one egg could lead to another.””
