Canadian Catholic is apparently an "ex-atheist" who thinks that you can't get to a cockroach brain to a human brain via evolution
I'm not a Canadian or a Catholic, and despite all his reasons being wrong, he's still basically right even for the wrong reasons. Evolution doesn't remotely suggest that if we took any extant animal and applied tailored forces that we'd be able to turn it, over billions of generations, into a human.
Rather, a human and a cockroach share a common ancestor, and thus both our ancestors had a particular brain from which, through contingent selection pressures and statistical shuffling of genes, both cockroaches and humans evolved.
