Reconnection and Speciation Rates

Art Connections

Figure If two species eat a different diet but one of the food sources is eliminated and both species are forced to eat the same foods, what change in the hybrid zone is most likely to occur?

Hint:

Figure Fusion is most likely to occur because the two species will interact more and similar traits in food acquisition will be selected.

Figure Which of the following statements is false?

  1. Punctuated equilibrium is most likely to occur in a small population that experiences a rapid change in its environment.
  2. Punctuated equilibrium is most likely to occur in a large population that lives in a stable climate.
  3. Gradual speciation is most likely to occur in species that live in a stable climate.
  4. Gradual speciation and punctuated equilibrium both result in the evolution of new species.

Hint:
