Unit 10 Ecology and Evolution

Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest

• Natural Selection

• Population

• Sexual Selection

• Fitness

A group of organisms of the same species living in a particular area at the same time

• Species

• Gene Pool

• Population

• Phylogeny

Frequencies of alleles and genotypes in a population remain constant from generation to generation when no selection occurs.

• Gene Flow

• Hardy-Weinberg Principle

• Speciation

• Coevolution

Unpredictable change in allele frequencies of a population over time due to random and chance events.

• Adaptation

• Divergent Evolution

• Hardy-Weinberg Principle

• Genetic Drift

Describes the movement of individuals between populations resulting in the mixing of genes between the populations.

• Gene Flow

• Genetic Drift

• Divergent Evolution

• Coevolution

Mate choice affecting the traits of a species.

• Adaptation

• Fitness

• Natural Selection

• Sexual Selection

A trait that helps a population survive

• Fitness

• Adaptation

• Divergent Evolution

• Coevolution

The ability to survive to maturity, find a mate, and produce offspring that live to be adults.

• Natural Selection

• Gene Flow

• Fitness

• Adaptation

The copies of every type of allele at every locus in a population.

• Species

• Gene Pool

• Phogeny

• Primary Succession

A group of similar organisms that can breed and produce fertile offspring.
