Article excerpt (with my emphasis): “With the explosion of molecular biology in the 1980s, it became clear that P450 genes existed in virtually all species—from prokaryotes to rodents and humans , and alignment of deduced amino acid sequences led to the first proposal of a gene superfamily nomenclature system based on evolutionary divergence . This evolutionary concept also implied that all CYP genes today arose from a single ancestor, which originated probably more than 3 billion years ago.‘
My comment: This is an open access article. Any advocate of adaptive evolution via random mutations can attempt to find evidence that I could not find by scanning it. Please tell someone when you find it, and if you don’t tell them why you think anyone would believe in such a ridiculous theory as a basis for adaptively evolved human behavior.
