About 3 years ago I had a conversation with Denis Alexander (
https://en.wikipedia.org/wiki/Denis_Alexander) about evolution. I asked him, "How can we understand purpose in biological and chemical processes?" One of things he said was, "You can’t derive “purpose” from biology, but biology is not purposelessness. Evolutionary biology doesn’t look like just rocks on the beach, strewn about randomly. In biology many designs converge. When you look at evolutionary history, it’s all highly organized. It’s not random in any sense. Evolution is not a chance process (Dawkins). It’s highly organized and not a chance process. 'Human beings were not a random accident but that something like a human is a predictable outcome of the evolutionary process: It’s more like solving a puzzle than writing a novel' (Conway Morris)."
He also said that mutations are not random. "Mathematically that’s not true. If you look at mutations where the genome is sequenced, every baby has approximately 60 new mutations. Those are not random—they come in clusters (they tend to occur at certain points in the genome far more than at other points). If they were random, they could come in any position, but they’re not. They’re not randomly generated.
"If you look at the periodic table, the elements all have properties that define what they can do. The whole of chemistry is highly organized (fine-tuned) and not really “'random”' at all.
So it seems to me that biology is not purposeless. I had a conversation with Dr. Sarah Bodbyl Roels, who said that biological evolution can neither acc irately be described as purposeful or purposeless: "It’s like the system has been gamed for success, as if life has been rigged to move forward against all obstacles. ... The system displays a clear advantage over sheer randomization."
I'm pretty sure it's not accurate to say, "It really is that simple."
