"There's Plenty of Time for Evolution"?

-
PNAS has an article titled There’s plenty of time for evolution, however until someone knows if the transformations required are even possible the authors and anyone who believes their pap are full of shit.

For example Andrea Bottaro said the following over at the panda’s thumb:

Eyes are formed via long and complex developmental genetic networks/cascades, which we are only beginning to understand, and of which Pax6/eyeless (the gene in question, in mammals and Drosophila, respectively) merely constitutes one of the initial elements.

IOW the only evidence for the evolution of the vision system is that we have observed varying degrees of complexity in living organisms, from simple light sensitive spots on unicellular organisms to the vision system of more complex metazoans, and we “know” that the first population(s) of living organisms didn’t have either. Therefore the vision system “evolved”.

Isn’t evolutionary “science” great!

I say the above because if Dr Bottaro is correct then we really have no idea whether or not the vision system could have evolved from a population or populations that did not have one.

Any issues just throw Father Time at it...
