Here is what caused evolution.

Darwin studied animals, noticed the differences between animals in different parts of the world, then came up with a theory. Voila! Evolution was born(or at least, modern evolutionary theorem).

Now, the biggest fallacy with the question "What is the cause of evoluton" is the assumption that evolution is true. Evolution is a theory, not a fact.

In theory, certain 'ingrediants' combine at just the right time at just the right tempature at just the right speed at just the right everything to become something more complex. In theory, this kept happening, eventually leading to the development of homo sapiens.

There are numerous flaws and fallacies within the theorem. If I get bored enough to read the other evolution topic, I might post about the flaws and fallacies there, but it definitely won't be tonight.
