Charles Darwin, himself a proponent of pangenesis, publishes On the Origin of Species his explanation of evolution by natural selection. Darwin provides a plethora of evidence on how valuable traits become more common in a population, but does not provide any explanation for the mechanism of transmission of these traits.

Expert Solution
Step 1

Though Darwin wasn't sure of the mechanism by which traits were passed on, he did not believe that evolution necessarily moved toward greater complexity, according to Understanding Evolution - rather, he believed that complexity arose through natural selection. Darwin's critics raised a major objection to his theory that the actions of selection would inevitably deplete variation in populations and make it impossible for natural selection to continue, He could not explain how variation maintained, because he did not understand the mechanics of inheritance, The solution of these problems required an understanding of genetics, which was not available for another half-century.
