Here's an overly simplified analogy of my own, so as not to steal from the author. Evolution can't make much progress taking 50 steps backward for every step forward. That's something I've long believed, but I haven't proven it myself.
Well as you didn’t post his analogy let me comment on yours. How would I sound if I said science cannot really progress since the vast majority of humans fail to get advanced degrees or contribute to the advancement of science?
Let me ask you a question, if the author is putting forward the claim in a manner close to how you present it here, does the author explain why all life simply doesn’t end? Consider if the steps are as backwards as you seem to suggest then why don’t we simply mutate ourselves out of existence?
