Document Summary

Limits on population growth: war, famine, disease, high infant mortality, abstinence, coitus interruptis (birth control) . Population sizes kept stable: prevent some young from reaching adulthood, and prevent some from reproducing . Considerable variation in form (within any population or species) These individuals live longer and produce more offspring. Produce more offspring (because they inherited good traits) Process continues until better adapted variation becomes normal . Variations not as adapted are weeded (die off) out by environmental pressure . Principle of natural selection: survival of the fittest . Fittest does not equal darwinian fitness (big does not equal best) . Best strategy to ensure inheritance of genotype: produce as many healthy, and well-cared for offspring as possible . Trade-off between having many poorer-cared vs. fewer better-cared offspring . Those who do not reproduce either because they are sterile or unwilling - Alfred russel wallace (young naturalist) published article with darwin .
