Plant Sciences, Zoology & Evolution / Are sharks and crocodiles evidence of Lamarckian evolution?
« on: 04/06/2010 17:00:13 »
From what I have always heard, both sharks(some) and crocodiles as well as a few others have not really evolved in the past 65 million years or so. It seems to me that all the species I have heard of which have not evolved are extremely well suited for their environment. Does this provide evidence that evolution happens as Jean Baptiste Lamarck suggested, because it is needed, and that if no evolution is needed no evolution occurs?
