Document Summary

Differential reproductive success (i. e. , difference among individuals in the. Fitness relative reproductive success (an attempt to quantify natural. The individual organism is the unit or target of natural selection. The selection) population, or species (depending on level of organization we are looking at), is the unit of evolution. The ability for natural selection to cause evolution is directly related to the heritability of those traits. Natural selection (h2) acts directly on ones phenotype (p in above formula) Adaptation is the result of natural selection. Is an increase in the frequency of and only indirectly on genotype (g in formula) traits in a population or species that allows organisms to survive their environmental stresses. Individual organisms do not adapt, it is the group. All adaptation says is that evolution has occurred (it is the long term effect of natural selection) **fundamental theorem of natural selection** (not in text)
