Chittenden Natural Selection
evolution | The process of biological change in populations over time that makes descendants genetically different from their ancestors. |
microevolution | Evolution can occur on a small scale affecting a single population |
macroevolution | Evolution on a large scale affecting changes in species across populations |
natural selection | mechanism for how evolution occurs |
fitness | a measure of how well you can survive in your environment |
adaptation | a feature that allows an organism to better survive in its environment |
gene pool | the combined alleles of all individuals in a population |
genetic drift | random change in the frequency of alleles i a population over time |
gene flow | movement of genes into/out of a population |
sexual selection | the selection of traits that aren’t necessarily good for survival fitness, but without them, you can't pass on your genes at all because you can’t reproduce |
genetic equilibrium | Hardy Weinberg Equilibrium; when there are NO changes in the allele frequencies in a population over time |
