If you don't, go directly to The Skeptic Series and answer that question first. It's been said evolution is a fact, with just a few details left to work out. But if you have studied science much, you can recall another time when science had the same amount of assurance - just at the first part of the 1900's. Physicists thought they had all the laws of physics explained, with just a few details left to work out. But along came a guy by the name of Einstein who shattered their comfort with a new branch of physics called quantum mechanics.
Pride goes before destruction, And a haughty spirit before a fall.
Better to be of a humble spirit with the lowly, than to divide the spoil with the proud. The following is only a brief summary of a few problems with the current theory. Each by itself could be the topic of a book - the goal here is to illustrate a few things to think about in regards to evolution. Any person putting their faith in the theory of evolution must have answers for these questions. These are not just minor details to work out, they are fundamental issues that must be resolved for the theory to have credibility.
