Read it, or better yet open a 10th grade biology school textbook, or read up on evolution (from scientific sources) and decide for yourself. Its also a shock to see that your lot consider a professor of biology from the University of Oxford(a very credible place, if you know anything about education) to not be credible, despite being an expert in his field, due to ONE question asked by someone with clearly ulterior and biased motives and his subsequent silence as 'proof' that the questioner and his question were, in fact, credible. As for my link, it spells it out more or less, see the problem with creationists and their arguments is that 'credible' scientists and studies dont take them seriously enough to answer their specific(read: misleading and deliberately distorted ) questions.
