What Is Evolution?

May 1, 2009


The debate over evolution can be confusing because equivocation has crept into the discussion. Some people use “evolution” to refer to something as simple as small changes in the sizes of bird beaks. Others use the same word to mean something much more far-reaching. Used one way, the term “evolution” isn’t controversial at all; used another way, it’s hotly debated. Used equivocally, “evolution” is too imprecise to be useful in a scientific discussion. Darwin’s theory is not a single idea. Instead, it is made up of several related ideas, each supported by specific arguments:

When you see the word evolution, you should ask yourself, “Which of the three definitions is being used?” Most critics of neo-Darwinism today focus on Evolution #2 or Evolution #3. But the discussion gets confusing when someone takes evidence for Evolution #1 and tries to make it look like it supports Evolution #2 or Evolution #3. Conversely, someone may discuss problems with Evolution #2 or Evolution #3, but is then falsely accused of rejecting Evolution #1, as well. This is simply not the case, for even biologists who dissent from neo-Darwinism accept Evolution #1.
