The Theory of Evolution


Evolution functions on these basic premises:

  • There are a number of imperfect replicators on Earth competing for limited resources (food / land)
  • The environment that these imperfect replicators inhabit determine which replicators are
  • successful and which ones are not by means of reproductive success.
  • Child replicators inherit their parents' DNA, this includes all positive, negative, and neutral replication errors.
  • The combination of these factors (imperfect replicators + limited resources + heritability) is what is responsible for the diverse number of species on the planet.

In order for a scientific theory to be successful, it has to explain what's going on in nature better than any other theories. Below is a list of empirical evidence (things we observe happening/going on in nature) that need explanation:

The above list is a list (not all-inclusive) of the things we find in nature that need a biological explanation. The Theory of Evolution is the scientific theory that attempts to explain why we find these things happening in nature - such as birds with teeth. Birds having genes for teeth is strong evidence that they had an ancestor that did have teeth (dinosaurs).

All birds have genes for teeth that are not "turned on", just like all humans have genes for tails that are not turned on (most of the time).

Then we have Creationism. Creationists are people who believe that, in this context, life on Earth was willed into existence by their god(s). Creationsim is anti-science right off the bat - they start with their conclusion and try to shoe-horn the Universe into their assumed conclusion, ignoring any evidence to the contrary:

One side's methodology is extremely biased, the other's is objective. Which is which?

Most Creationists function under the false axiom that if they "prove" the Theory of Evolution false, this means that Creationism is true. This is could be categorized under the logical fallacy of a False Dichotomy. Proving the ToE false in no way means that Creationism is true. In order for Creationism to be found true, Creationists would have to provide evidence of creation.

Once that happened, then the Creationist would have to provide evidence that their respective god(s) did indeed perform the creation event.
