Define “evolution”
Explain three pieces of evidence that fossils provide that evolution has occurred
Contrast analogous structures and homologous structures
Analogous:
Homologous:
Use an example to explain how selective breeding has lead to evolution in a species
Define “strata” and “paleontology”
Strata:
Paleontology:
Explain the process of artificial selection using selective breeding
Contrast convergent evolution and adaptive radiation
Convergent evolution:
Adaptive radiation:
Define “vestigial structure”
State an example of homologous structures
State an example of analogous structures
State an example of a vestigial structure
Describe the process of gradual speciation
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
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
Explain how natural selection leads to changes in the melanistic variety of insects in polluted areas
Propose a mechanism that explains the pattern found in vertebrate limb structure yet allows for the specialization of different limb functions
Define “variation”
Explain why natural selection can only function if there is variation in a species
List sources of genetic variation
Mutation, meiosis, sexual reproduction
Define “adaptation”
