All I need to know is that genetic engineering has the potential to reshape the genome such that massive changes in morphology are possible.
That's grade school. We are talking way beyond that. No wonder you're lost.
Believing that your puny mechanisms of evolutionary can turn a rodent into a whale is grand delusion.
A grand delusion of actual fact. And we got pictures. With circles and arrows and a paragraph on the back of each one saying what each one was. Yea, Dredge, we know the lineages quite well and with a lot more consensus than you could afford to admit.
