is heritable) and arises through processes such as mutation and recombination.
 Natural selection, gene flow and random genetic drift (the random change in gene combinations with each generation) drive evolution, resulting in a change in gene frequencies within populations .
methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.
