Question

The one-toed horse of today steadily evolved from its five-toed ancestor. Which theory of evolution can explain this example?

Answer 1

The answer is C: gradulism.

Gradualism describes the rates of speciation. It means that evolutionary changes in species are slow, gradual and continuous process. In our example, The one-toed horse of today steadily evolved from its five-toed ancestor. Steadily is the key word. So, the change was slow and continuous process.

If the change were rapid, this would be an example of punctuated equilibrium.
