How Evolution Works
Assuming that they believe in evolution at all, many people believe that organisms evolve because of changes in their environment. For example, if the earth suddenly got really hot, animals might evolve to have less hair in order to adapt to that climate.
The problem with this approach to evolution is that it implies that evolution is some kind of conscious or unconscious change made by an organism, which is simply false. Organisms evolve when random genetic changes give them a survival advantage over organisms that don’t have those changes. For more details, check out my episode on Evolution and Super Goblins.
