An Example of Natural Evolution?

-
Arthur Hunt turned up @ Joshua Swamidass's forum touting plant evolution- specifically Silverswords- as evidence for something.


Art's interesting evidence

Art says:

By a standard that even the staunchest YECer accepts, it can be strongly concluded that each of these (as well as other members of the Silversword alliance) share a common ancestry.  This is because, the vast morphological differences aside, they are interfertile.  

That is not so, Art. YECs accept that plants can hybridize. Reproduction after the Kind is limited to animals. It means nothing.

As interestingly, for a number of other reasons (biological, geographic, historical, and molecular), it can be safely concluded that these vastly-different plants diverged from a common ancestor that looked something like

And Dr Spetner's "built-in responses to environmental cues" explains the morphological differences.

What natural evolution fails to do is account for the regulatory networks in the first place. So that is an issue that you and yours always overlook.

So no, Art did not present a case of natural evolution. That is just question-begging
