What role do homologous structures play in the study of evolution?

• They provide evidence of common ancestry among different species

• They indicate the age of fossils

• They show how different species have evolved independently

• They demonstrate the genetic differences between species

How does increased variation in individuals improve the chance a population survives?

• Variation allows individuals who are very different from the rest of the population to reproduce more successfully than “normal” individuals

• Variation allows the population to survive changes in the environment because traits that are suited to the new environment may already exist in the population

• Variation is having a variety of hobbies, like how Mr. Smith is a teacher and an artist going by the name "M.C. Smithsonian"

• Variation allows the population to produce offspring that will survive into adulthood
