Question

What do gradualism and punctuated equilibrium have in common?

Answer 1

Both gradualism and punctuated equilibrium are talking about the same thing - the change of traits. However, it is true that neither of the two are completely correct as actual trait changing involves parts from both. It is also true that punctuated equilibrium is slightly biased because it is less commonly the case that something changes in one point.

Answer 2

Both theories agree that evolution occurs gradually.

Step-by-step explanation:

Both are evolution theories. The theory of gradualism was supported by Charles Darwin. This theory says that the evolution of some trait of a species occurs slowly over time and gradually. In contrast, the theory of punctuated gradualism says that these jumps in species do not occur gradually. If not they are sudden. Or that in time periods they are absent and in others they are much faster. Both theories agree that evolution occurs gradually. They differ in how those changes graduate.
