Question

7. According to Darwin’s theory of natural selection, certain individuals will leave more offspring on average than do other individuals. Their survival is due to the a. possession of adaptations developed through use b. possession of inherited adaptations that are well suited to the environment c. lack of competition within the species d. choices made by plant and animal breeders 8. The combined alleles of all the individuals that make up a population is the population’s a. relative frequency b. phenotype c. genotype d. gene pool 9. When lions prey on a herd of antelopes, some antelopes are killed and some escape and live to reproduce. Which best describes this situation? a. an individual passes along acquired characteristics to the next generation b. natural selection is a random process c. individuals that function best tend to leave the most offspring d. species remain unchanged throughout time 10. Biological fitness is the ability of the individual to a. live to reproductive age b. contribute to the gene pool of the next generation c. adapt to environmental conditions d. acquire new characteristics True/False – If the statement is false, change the identified word or phrase to make the sentence or statement true. 11 After his voyage on the HMS Beagle, Darwin wondered whether similar species form the Galapagos Islands could once have been members of the same species. 12. Darwin came to realize that organisms of the same species are identical to on another. 13. The term “fitness” refers to an organism’s ability to survive and reproduce in a specific environment, contributing genes to the next generation’s gene pool. 14. In 1858, Alfred Wallace sent Charles Darwin a letter proposing a mechanism for evolution that was very similar to Darwin’s. 15. The fact that species today look different from their ancestors can be described as descent with modification.
