Interesting but the poster of this video makes some mistakes and omits some facts.
That humans evolved from other animals was first posited by the ancient Greek Anaximander of Miletus and Epicurus amongst others, and throughout history but it wasnt until Darwin and Wallace really had the mechanism of Natural Selection nailed down.
The video poster and Sir William Draper both also make the same mistake that Islamic apologists do in that although Ibn Khaldun, may have considered himself Muslim, it was not because of the truth of Islam or from reading the Quran that he reached this conclusion, but rather by observation of the natural world and his reasoning (ie Science). To call Khaldun's great works 'a product of Mohamed' is asinine. If Khaldun was alive today and made his claim in any mosque, I dare say he would receive the same anger that Usama Hasan did.
Also in any case, his works contradict the Quran, and both Draper's and the poster's claim that evolution was the 'Mohamedan Theory of Evolution' or predicted by Mohamed is laughable. Just ask Usama Hasan what reaction he received at Leyton Mosque when he suggested that man evolved from apes and the implication that had for the claims in the Quran.
This is why I never use the term ISLAMIC Golden Age, because it is generally assumed that this proves the religion or the god they worship so I say 'ARABIC Golden Age".
No-one would suggest that what any historical scientist discovered was any proof of the god he may have worshipped. Same with this video.
Any Christian or Muslim who claims that evolution is in their holy book I would like to present Robert Ingersoll's quote on the matter:"The Church demonstrated the falsity and folly of Darwin's theories by showing that they contradicted the Mosaic account of creation, and now that the theories of Darwin having been fairly established, the Church says that the Mosaic account is true because it is in harmony with Darwin. Now, if it should turn out that Darwin was mistaken, what then?"
To accentuate the issue, lets say that evolution was proven wrong tomorrow, and science claims that the earth and all living things were really created in 6 days, then evolutionist Muslims and Christians would drop Darwin like a hot potato and claim that the bible/quran was correct all along.
