UNIT 8 EVOLUTION

A trait or change in lifestyle that helps a plant or animal survive in its environment

• adaptation

• evolution

• homologous

• vestigial

When HUMANS select or choose a plant or animal for breeding based on a desired trait

• natural selection

• artificial selection

Shows how different groups of organisms have changed over time.

• fossil record

• homologous structures

• embryology

Parts of the body that are similar to other species because they have a common ancestor

• fossil record

• homologous structures

• embryology

Body part you have that use to have a purpose but now has little or no function

• vestigial organ

• embryology

• homologous structures

When living organisms that are not closely related have very similar DNA bases it means they had a common ancestor

• biomechanical evidence

• embryology

• fossil record

• homologous structures

Scientist that contributed the most to our understanding of evolution

• Darwin

• Lamarck

Organisms with the best suited adaptations for their environment are more likely to survive and reproduce than organisms that are not very well adapted

• natural selection

• artificial selection

• creationism

Organisms from the same species can vary in…

1) physical appearance

2) genetic makeup

• overproduction

• variation

• selection

• adaptation

Species not closely related evolve similar traits due to their similar environment

• Convergent evolution

• divergent evolution

• parallel evolution
