But one last. "He" calls "evolution" (whatever "he" means by that) a tautology and calls it false on that basis. The thing is that a tautology is always true; it's just trivially true (ie, offers no actual explanation) and hence not useful. But it's still true.
The most popular target for the claims of tautology is natural selection. It is trivially true that those who have more grandchildren will have more of their genes in that generation. It is also trivially true that certain alleles increase the chances of having more grandchildren compared to those in the population who don't have that allele.
So yes, it may be a tautology. That also makes it true.
What isn't a tautology is the evidence demonstrating that the morphology and genomes of living species are a product of this mechanism, in addition to other mechanisms such as constructive neutral evolution.
