Document Summary
In order for ns to occur, traits must be genetically inherited. Cannot occur unless there is variation between individuals. W/o variation there is always the same characteristics passed on from generation to generation. Fitness: a measure of how adapted you are to your environment. The individuals ability to have offspring that will survive and reproduce. Sometimes adapting to your environment isn"t necessarily beneficial throughout life - what once may have given a species an edge may turn out to be very limiting. A trait must be inherited to have importance in natural selection. Fitness is a relative measure that will change as the environment changes. Fitness is simply understood as differential reproductive success. Mendell: first discovered heredity -> used basic math in biology to make discovery.
