DAVID: Life keeps reinventing parts:-http://www.the-scientist.com//?articles.view/articleNo/39332/title/Convergent-Fish-Fins/-This must be a built-in capacity that drives evolution (Simon Conway Morris toward humans.-And of course towards all the other animals with limbs and all the later fish with fins. Unfortunately, however, it seems that even the researchers themselves aren't sure of anything:
 
QUOTE: They have good evidence here that the adipose fin may be a good model for understanding the origins of limbs and fins," said Peter Wainwright, a biologist at the University of California, Davis, who was not involved in the research. "They're essentially charting a course for future research here."
But Wainwright cautioned that it's too soon to tell whether this insight can be used to study how limbs and other types of fins developed. "It may just turn out that the origins of adipose fins are somehow unique and different from the origin of other fins," he said. "We don't know how good a model it will be. We'll just have to wait and see how that work pans out."-Well, let me know when they prove that your God planned the adipose fin as a mere stepping stone to human arms and legs...
