Document Summary

Diversity of genetics at all levels of organization. Individuals that can reproduce and have babies that are fertile. Species diversity: richness = the number of species, evenness = (relative abundance) the similarity in numbers between species. Speciation adds to species richness: extinction reduces species richness. Taxonomists: scientists who classify species, similarities reflect evolutionary relationships, genera= groups of related species, families = groups of genera. Every species has a two-part scientific name: genus and species. Subspecies: populations of species that occur in different areas and differ slightly from each other, divergence stops short of separating the species, subspecies are denoted with a third part of the scientific name. Encompasses the differences in dna among individuals. The raw material for adaptation to local conditions. Populations with higher genetic diversity can survive: they can cope with environmental change. Populations with low genetic diversity are vulnerable to environmental change or disease.
