The concept that species evolve slowly and continuously over long periods of time is known as:

• Punctuated Equilibrium

• Gradualism

• Catastrophism

• Uniformitarianism

Which of the following best describes gradualism in evolutionary biology?

In the context of gradualism, which type of fossil record would you expect to find?

• Abrupt transitions between species

• Continuous and incremental changes

• No changes over time
