The new species of worm was a new species. What don't you understand?.Two points. The term "species" is a slippery one. The decision where to draw the line when two lines of descent diverge is a human one. This leaves room for apologists to wriggle out of - all they need to say is "I don't agree with your definition of a species therefore a new species didn't appear". Second, they get wriggle room from the biblical term "kind". They can argue (and have done so with me) that kind is not the same as species.
In all of this they loose sight of the fact that they are beginning to accept the fact of evolution is a given, and are just arguing about terminology.
And none of them has ever come up with a reason to support their contention that there is a qualitative difference between macro and micro evolution. Not one of them has ever defined exactly what prevents micro evolution turning into macro evolution given sufficient time.
