- Quizlet study set for this topic
5.1.U1 Evolution occurs when heritable characteristics of species change.
- Define evolution.
5.1.U2 The fossil record provides evidence for evolution.
- Define strata and paleontology.
- Explain three pieces of evidence that fossils provide that evolution has occurred.
5.1.U3 Selective breeding of domesticated animals shows that artificial selection can cause evolution.
- Use an example to explain how selective breeding has lead to evolution in a species.
- Explain the process of artificial selection using selective breeding.
5.1.U4 Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function.
- Contrast analogous structures and homologous structures.
- Contrast convergent evolution and adaptive radiation.
- State an example of analogous structures.
- State an example of homologous structures.
- Define vestigial structure.
- State an example of a vestigial structure.
5.1.U5 Populations of a species can gradually diverge into separate species by evolution.
- Describe the process of gradual speciation.
5.1.U6 Continuous variation across the geographical range of related populations matches the concept of gradual divergence.
- Explain how continuous variation across geographical ranges is evidence of evolutionary change.
- State an example of recognizably different populations of the same species across a geographical range.
5.1.A1 Comparison of the pentadactyl limb of mammals, birds, amphibians, and reptiles with different methods of locomotion.
- Define pentadactyl limb.
- List the bone structures present in the pentadactyl limb.
- Identify pentadactyl limb structures in diagrams of amphibians, reptiles, birds and mammals.
- Relate differences in pentadactyl limb structures to differences in limb function.
5.1.A2 Development of melanistic insects in polluted areas.
- Explain how natural selection leads to changes in the melanistic variety of insects in polluted areas.
5.1.NOS Looking for patterns, trends and discrepancies- there are common features in the bone structure of vertebrate limbs despite their varied use.
- Propose a mechanism that explains the pattern found in vertebrate limb structure yet allows for the specialization of different limb functions.
