You're studying two species of frog. How would you know if gradualism or punctuated equilibrium played a role in the formation of the two species from their common ancestor?

A) The species would have more differences if speciation occurred gradually.
B) The species would have more differences if speciation occurred suddenly.
C) The species would be the same regardless of how the speciation occurred.
D) The degree of difference depends less on the mechanism of speciation than on the time that's passed since speciation occurred.
