HS.LS-NSE Natural Selection and Evolution April 25, 2012
... Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals. (a),(c) The traits that p ...

... Darwin’s Four postulates (criteria) 1. Individuals within a population vary in traits 2. Variation must be heritable (genes/DNA) 3. In every generation, more offspring are produced than can survive. Only some individuals survive to reproduce. 4. Survival and reproduction of individuals is not random ...

Evolution is the biological history of life on Earth, from the earliest
... Evolution: the process in which changes in the inheritable traits (ie. the genes) of species occur over time. (It follows that all modern-day species are descendants of ancient species, which were very genetically different.) Adaptation: any inheritable trait that increases an individual’s ability t ...
