What i can't understand about evolution....

Hi all,
I have considered the theory evolution, and to me it just does not seem plausible, even practical. If we developed by a series of genetic malformations, this would obviously take rather a long time. But how come some developments, for example fins to legs, the circulatory system, internal organs, wings, surely the development of these would have to be instanaeous and perfect to give them any advantage at all, or to even work?Edited by Integral, : No reason given.

i do love this reaction...
Ok first of all i do have a fairly adequate knowledge of Biology and do understand about variation and how evolution happens. Im not disputing that evolution does happen, phenotypes vary, there is evidence for that. Bird beaks will get larger or smaller as one type of bird becomes more adapted to its environment for example. So please understand that i'm not disputing evolution on the small scale.The only thing that i cannot quite get my head round is that fact that you are using these very small scale examples and multiply there impact over millions of years to explain the existence of the life on this planet... I do not see how a fish with a single circulatory system evolves into a land mammal with a double circulatory system for example. Its these sort of huge jumps from species to species that i dispute.And yes you are right my knowledge of the general theory of evolution is basic, but i hope to change that.And to adress the point that was made that evolution has so much more evidence, i was under the belief that there is really not that much evidence at all. For example i read in the "national Geographic" a magazine that promotes evolution, that evoltuion is obviously you have reasons why there are gaps in the fossil record, but you would think there would be a little moe evidence.thank you for your well thought out arguments...Edited by Integral, : No reason given.Edited by Integral, : No reason given.Edited by Integral, : No reason given.Edited by Integral, : No reason given.
