Retake Review for Unit 10 Natural Selection and Evolution

Answer each question using complete sentences. Use the required vocabulary in your responses where appropriate. This review will help you prepare for your retake on natural selection and evolution.

Explain how homologous structures and vestigial structures provide evidence for common ancestry. Use the terms 'Common Ancestry,' 'Homologous Structures,' and 'Vestigial Structures' in your answer.

List and describe the five requirements for natural selection. Be sure to use the terms 'Genetic Variation,' 'Inheritance,' 'Natural Selection,' ‘Time,' and 'Adaptation.'

Describe how natural selection can lead to evolution in a population. In your answer, use the terms 'natural selection,' 'evolution,' 'genetic variation,' 'inheritance,' 'adaptation,' 'genotype,' and 'phenotype.'

In the Rock Pocket Mouse population, a change in the environment caused dark-colored mice to survive better than light-colored mice. Explain how this affected allele frequency and the gene pool over time. Use the terms 'natural selection,' 'evolution,' 'genetic variation,' 'inheritance,' 'adaptation,' 'allele frequency,' 'gene pool,' 'genotype,' and 'phenotype.'

Suppose a population of birds moves to an island where only large seeds are available. Predict how the frequency of genotypes and phenotypes related to beak size might change over time. Use the terms 'natural selection,' 'evolutionary fitness,' 'genetic variation,' 'inheritance,' 'adaptation,' 'genotype,' and 'phenotype.'
