The following video shows a lecture by an American cell biologist named Kenneth Miller. He effectively and conclusively argues that Intelligent Design has no place whatsoever in science. If there are any religious people reading this (which I doubt) and prepared to ignore it on the basis of the dude being another atheist blasphemer – take note that he is a practicing Roman Catholic, and that some priest/bischopish dude even blesses the lecture before it starts.
The length of the video is about two hours in total; the length of the lecture itself is one hour and ten minutes. I found it very informative and entertaining.
Apparently, some sixteen years ago Richard Dawkins did a series of Christmas lectures at the Royal Institution of Great Britain. He talks about evolution and such to a large amount of children with funny hairdos. The fourth lecture (there are five) even features Douglas Adams! How neat is that.
Anyway, a bloke calling himself DrMontague has posted these lectures on YouTube. They are positively stunning, very entertaining and leave you with a sense of wonder about the world and the universe. Each lasts about an hour, but I can guarantee that they will capture your attention just as well as an intriguing film would. Many YouTubers rightfully comment that they wish every teacher would be like Dawkins.
