If, like the horse, all of the transitional forms for a species are found in the fossil record, which model of evolution most likely occurred in that species?

• punctuated equilibrium
• gradualism
• adaptive radiation
• convergent evolution

Species change slowly: Supported by the fossil record

• gradualism

• punctuated equilibrium

new species evole rapidly: Stays the same for long periods of time: Evolution sudden or rarely happens

• gradualism

• punctuated equilibrium
