Macroevolution, Microevolution, and Human Evolution Quiz

This diagram illustrates which kind of evolutionary pattern?

• Convergent evolution

• Stabilizing selection

• Directional selection

• Adaptive radiation

Which of the following lines of evidence shows that whales are descended from a land-dwelling, four-legged ancestor?

• Whales have bone structures in their forelimbs and pelvis that are similar to those of terrestrial mammals

• Whale embyros have similar structure to embryos of land-dwelling mammals, birds, and reptiles.

• An analysis of DNA shows that whales' closest living relatives are hippopotamuses.

• A, B, and C

Which two types of animals show evidence of convergent evolution?

• Frogs and lizards

• Dogs and wolves

• Dolphins and sharks

• Worms and insects

Which of the following statements accurately describes the role of mutations in evolutiont

• Mutations are the raw material for evolution, but most mutations do not result in evolution.

• Most mutations result in a species becoming more dangerous or aggressive.

• An organisms can decide to mutate if the environment makes a mutation necessary for survival.

• Mutations are almost always beneficial for an individual.

During microevolution, a(n) __________________ will become more or less common within a population.

• species

• allele

• ribosome

• fossil

This diagram of forelimbs of various of various mammals and birds is an example of:

• analogous structures

• homologous structures

• adaptive radiation

• speciation

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age

• Fossil A is older than Fossil B

• Fossil B is older than Fossil C

• Fossil D is older than Fossil C

Which of the following is required for a population to diverge into two separate species?

• The two populations must have evolved different physical appearances.

• The two populations must have mutated at least 10 times.

• The two populations must have become reproductively isolated.

• The two populations must have evolved analogous structures.

Which of the following is NOT a unique trait that evolved in humans?

• Bipedalism

• A large cranium

• Canine Teeth

• Use of tools

The palmarus longus tendon, pictured here, no longer serves a purpose in humans, but provides evidence of our species descendance from tree-dwelling ancestors. The palmarus longus tendon is an example of:

• a vestigial structure

• a homologous structure

• bipedalism

• convergent evolution
