Evolutionary biologists often comment that Darwin's genius (and Wallace's, lest we forget) was all the more impressive given that he had a mistaken understanding of the mechanism of heredity. Imagine that Darwin had known of Mendel's work as he was pondering evolution. In NO MORE THAN one page (less is fine!), speculate on how you think that might have affected his conclusions. Be sure to offer justification for your opinions.
