Document Summary
Nested hierarchy: refers to the way taxonomic groups fit neatly and completely inside other taxonomic groups. Biodiversity: the term given to the variety of life on earth. Diversity: number of species in a taxonomic group or a geographical area. Biological species concept: species are groups of interbreeding natural populations that are reproductively isolated from other such groups. Levels of organization: domain, kingdom, phylum, class, order, family, genus, species (populations within species) Species: groups of interbreeding natural populations that are reproductively isolated from other such groups. Population: group of interbreeding individuals and their offspring (for sexual species) Ontogeny: significant changes in morphology from youth to old age. Phenotypic plasticity: same genotype produces different phenotypes depending on the environment. Microsatellites: regions of the genome that do not code for proteins and vary widely in quantity among individuals. Disparity: how physically different species in an area are from each other.
