Abstract

The theory of evolution has provided an historical outlook for the science of biology and has demonstrated that all living organisms on earth are kin to one another - be this kinship distant or close - that they all have their origin in the simple protoplast, and that the living world is a continual, historical entity. Every branch of the science of biology is permeated with the idea of evolution, and each branch has made contributions to the theory of evolution. The theory of evolution is like a strand of red thread running through the entire science of biology
