7.3 Artificial Selection

Evolution is characterized by a change in the genetic makeup of a population over time and is supported by multiple lines of evidence. Explain how humans can affect diversity within a population. Through artificial selection, humans affect variation in other species. Explain the relationship between changes in the environment and evolutionary changes in the population. Convergent evolution occurs when similar selective pressures result in similar phenotypic adaptations in different populations or species.

artificial selection

humans artificially select which individuals survive instead of the environment

• plants/animals selectively bred to produce desired traits

convergent evolution

occurs when similar selective pressures result in similar phenotypic adaptations in different populations or species
