Population - ANSWER A group of individuals that belong to the same species and live in the same area Purpose of variability within a population - ANSWER - some genetic variants have advantages over others - natural selection can act on variation (if needed) genetic divergence - ANSWER the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often after the populations have become reproductively isolated for some ...

Biodiversity correct answers Describes variability of organisms Generated by evolution through speciation How is Biodiversity Measured? correct answers Species richness: # species in given area Genetic Variation: different versions of genes in species Community Comp: types of interactions (prey/predator) Ecosystem Diversity: how species interact with nonliving environment How is Biodiversity Organized? correct answers Time: when first evolved Taxonomy: naming/organizational sy...
