Definition
the degree to which an individual contributes genes to future generations
Term
fitness
Definition
the degree to which an individual contributes genes to future generations
Term
survival of the fittest
Definition
most fit organisms goes on to reproduce and pas its favorable traits to future generations (ability to survive and reproduce)
Term
postulate one
Definition
individuals with in a species vary
natural selection will act upon those individuals that have the traits best suited for that enviorment
ex:coat color in mice
Term
postulate number two
Definition
some of the variations found in the population are passed on to offspring
trait is agenetic basis and the most common and successful ones will be passed down to offspring

in every generation more offspring are produced than can survive
those organisms that do survive are more sucessful than others at breeding

the survival and reproduction success of individuals is not random
the individuals who survive and reproduce are those carrying the most favorable variations and are naturally selected
