I liked the points brought up by this video about The Theory of Evolution. It tells us that just looking at the different layers of sediment and rock and you can see how certain species have evolved over the years and the changes they exibit you can also see by looking in those same layers that some of those same species have become extinct and also how they have come back to existence in a similar form. This video also explains why we don't see monkeys turning into humans and why we don't see single celled organisms turning into frogs or even a multi-celled organism. This is because it takes thousands of years for a species to change and the only ones we can see some changes in are the ones that reproduce very quickly. Also they show bone structures of a whales flipper and then those of a human hand and you can plainly see the similarities between them; but how do you get a flipper from a fully funtional five finger hand or a water dependent mammal to a land dependent mammal?Even still this topic brings up more questions and more flaws in the information but like the others they are called theories for a reason because they are just that; a theory!
