Answer

Both theories suggest slow and steady change.

Answer

Both theories suggest rapid change followed by stability.

Answer

Gradualism suggests rapid change followed by stability, while punctuated equilibrium suggests slow and steady change.

Question 16

Which of the following scenarios best illustrates punctuated equilibrium?

Accepted Answer

A species of fish remains unchanged for millions of years, then rapidly evolves new traits in a few thousand years.

Answer

A species of insects shows no significant changes over a long period.

Answer

A species of birds gradually changes its beak size over millions of years.

Answer

A species of mammals slowly adapts to a changing environment over a long period.

Question 17

How does the fossil record support the theory of punctuated equilibrium?

Accepted Answer

The fossil record shows long periods of stability interrupted by short periods of rapid change.

Answer

The fossil record shows a continuous and gradual change in species over time.

Answer

The fossil record shows no evidence of change in species over time.

Answer

The fossil record shows that all species evolve at the same rate.

Question 18

Which of the following is an example of the founder effect?

Accepted Answer

A group of birds is blown by a storm to a new island, where they establish a new population.

Answer

A volcano erupts, wiping out most of a population, leaving only a few survivors.
