What is a major difference between Lamarckian and Darwinian evolution? A. how traits become more prevalent in a group

B. whether or not body parts are shaped by use

C. whether or not animals change over time

D. the environment affects how animals change

Given what we know, we can confirm that the major difference between Lamarckian and Darwinian evolution is if the environment affects how animals change.

The major difference here is that Darwinian evolution focuses greatly on randomized changes in genotypes that result in new species that may or may not be adapted to survival. On the other hand, Lamarckian evolution entails changes in the genotype of an organism directly caused by the effect of the environment on said organism.

Therefore, we can confirm that the major difference between Lamarckian and Darwinian evolution is if the environment affects how animals change.
