Multiple ChoiceWhich of the following is the best example of natural selection?The lifespan of a chimpanzee is extended to 60 years in captivityThe population size of giraffes changes over time as a result of immigrationA populations of bunnies select for brown fur when winter is approachingAnts develop poisonous chemicals in response to high predation
- 6. Multiple ChoiceThe different species of the Hawaiian honeycreepers shown all descended from a single species of North American bird. They now have different beaks, eat different food, sing different songs, and live in different environments on the islands. Which factor probably contributed MOST to the development of these different species?Loss of habitatGeographical isolationEgg sizePredation
- 7. Multiple ChoiceWhich of the following is the best evidence that mammals evolved from reptiles?Similarities in the diets of extinct reptiles and modern mammalsSimilarities in the average lifespans of modern reptile and modern mammalsFossils of ancient reptiles and mammals that appear together in the same layers of rock
- 8. Multiple ChoiceWhich of the following statements best explains why many different finch species originated from the single ancestral species?Populations adapted to environmental pressuresRecessive traits in populations were elimanted over timeIndividuals acquired unique characteristics during their lifetimesRandom mutations caused some individuals to have harmful traits
- 9. Multiple Choice
The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that -they live in the same type of environment.have slowly evolved to become herbivores.have a common ancestor.exchanged DNA in the past. - 10. Multiple ChoiceThe Galapagos Islands, a small group of islands off the coast of Ecuador, is home to reptiles such as the giant tortoise and the iguana. The eastern islands are much older than the islands to the west. Which statement about the origin of these reptiles is best supported by this information?The ancestor of each species came from different continents at different times.The common ancestors of the reptiles probably came from Equador.The common ancestor of each species evolved in Peru and came to the islands at the same time.
- 11. Multiple ChoiceWhat conclusions can be made based on this table shown?the American black bear and the giant panda are most closely relatedthe giant panda and the red panda are most closely relatedthe red panda and the racoon are the most closely related
- 12. Multiple ChoiceThe similarities among early stages of the embryos provide evidence that -these organisms evolved from a common ancestorthe organisms all retained their gills and tailsthe organisms belong to the same species
- 13. Multiple ChoiceScientists compare the limbs of organisms to look for evidence of common ancestry. These limbs provide evidence of common ancestry because they -perform the same functionare the same sizehave the same basic structureare parts of the same animal
- 14. Multiple ChoiceWhich evidence of common ancestry is being studied in this visual?biogeographyfossil recordanatomical homology

- 23. Multiple ChoiceWhat is the advantage of having different shaped beaks?To look different from other species.To be able to eat the food readily available in the environment.To protect itself against predators.To protect itself against prey.
- 24. Multiple ChoiceWhy are advantageous traits more likely to be passed onto offspring?Because they are more likely to survive and reproduce.Because they come from dominant alleles.Because they come from recessive alleles.Because the trait is an acquired phenotype.
