What is the main difference between gradualism and punctuated equilibrium?

• Gradualism involves rapid change; punctuated equilibrium is slow

• Gradualism involves slow change; punctuated equilibrium involves rapid bursts

• Both involve slow, steady change

• Punctuated equilibrium is slower than gradualism

Which model of evolution shows long, slow changes over time?

• Punctuated equilibrium

• Gradualism

• Natural selection

• Mutation

What best describes punctuated equilibrium?

• Constant small changes

• Sudden change followed by stability

• Slow and steady progress

• Continuous mutation

A species remains unchanged for millions of years, then quickly evolves. This is an example of:

• Gradualism

• Genetic drift

• Natural selection

• Punctuated equilibrium

A species evolves slowly over millions of years with many intermediate forms. This is:

• Punctuated equilibrium

• Mutation

• Gradualism

• Artificial selection

Which pattern is most likely to result in fewer transitional fossils?

• Gradualism

• Artificial selection

• Punctuated equilibrium

• Convergent evolution

Which of the following would best match gradualism?

• A staircase with steep drops

• A flat line with sharp jumps

• A gently rising ramp

• A wave pattern

Which of the following best represents punctuated equilibrium?

• A long ramp

• Sudden steps followed by flat sections

• Smooth, steady incline

• Gradual increase in size

What does “punctuated” refer to in punctuated equilibrium?

• Constant mutation

• Frequent small changes

• Bursts of rapid change

• Gradual transitions

Which model explains why some species appear suddenly in the fossil record without many intermediate forms?

• Gradualism

• Gene flow

• Punctuated equilibrium

• Adaptive radiation
