Why Grow and Develop

Organisms grow and develop if they are mortal. Reproduction is necessary to replace those organisms that die, and sexual reproduction requires cell division, the formation of tissues, and other forms of growth. Some forms of life reproduce asexually, in which one or a few cells are contributed by a parent and those cells eventually grow and develop into a new mature individual that is, in many ways, almost identical to the parent. Most species reproduce sexually, requiring a single cell with some biological material from each of two parents. In either case, the initial contribution of cells cannot look or behave in any way like the parent. To be like their parents, "... the new organisms will have to suffer changes before they become something approaching replicas of the old" (Newth, 1970).
