Document Summary
Chapter 2 the new science of evolutionary psychology. The three products of evolution: there are there products of the evolutionary process- adaptations, by-products (or concomitants) of adaptation, random effects (or noise, adaptation. An adaption may be defined as an inherited and reliably developing characteristic that came into existence through natural selection because it helped to solve a problem of survival or reproduction during the period of its evolution. An adaptation must have genes for that adaptation that are required for the passage of the adaptation from parent to children. Most adaptions cannot be traced to single genes but rather are products of many genes. Past environments selected the genes we have today, environments during a person"s lifetime are necessary for the proper development of adaptations, and current environments are responsible for activating adaptions once they developed. An adaptation must develop reliably among species members in all normal environments.
