Chapters 16,17,19 Final Review

The process of change over time

• Evolution

• Natural Selection

• Adaptation

• Fitness

Consists of ALL genes, including the different alleles for each gene, that are present in a population

• Genetic Drift

• Gene pool

• Population

• Allele Frequency

The scientist who developed a scientific theory of biological evolution that explains how modern organisms evolved over long periods of time through descent from common ancestors.

• Hutton

• Lyell

• Lamarack

• Darwin

Any heritable characteristic that increases an organism’s ability to survive and reproduce in its environment is called

• Natural selection

• Adaptation

• Fitness

• Artificial selection

When two or more species reproduce at different times

• Behavioral isolation

• Temporal isolation

• Reproductive isolation

• Geographic isolation

Structures inherited from ancestors but have lost most or all of their original function due to different selection pressures acting on the descendent

• Analogous structures

• Homologous structures

• Vestigial structures

• None

When allele frequencies change in result of the migration of small subgroups of a population

• Founder effect

• Bottleneck effect

• Genetic drift

• Gene pool

Structures that are shared by related species and that have been inherited from a common ancestor are called

• Analogous structures

• Homologous structures

• Vestigial structures

• none

When a dairy farmer chooses to breed the cows that give the most milk in the herd, the farmers are following the principle of

• Natural selection

• Common descent

• Artificial selection

• Biodiversity

When two populations that could interbreed, don’t breed due to the differences in courtship rituals

• Behavioral isolation

• Temporal isolation

• Geographic isolation

• None
