Document Summary
Diversity: number of species in a taxonomic group or geographical area. Species: groups of interbreeding natural populations that are reproductively isolated from other groups. Population: group of interbreeding individuals and their offspring. Levels of biological organization: domain, order, family, kingdom, genus, phyla, species, class. Evolution: the study of both adaptive and non-adaptive change over time in populations, the origin and extinction of species, and the relationships among living things. Ecology: the study of interrelationships between organisms, both living (biotic) and non-living. Nested hierarchy: the way taxonomic groups fit neatly and completely inside other taxonomic groups. Ontogeny: significant changes in morphology from youth to old age. Ontogenic variation: changes to an animal that occurs as it goes through life. Genetic variation: differences at the dna level among individuals within a population or species. Genotype: set of genes possessed by an organism. Phenotype: physical expression of the genotype in combination with environmental factors.
