And people have bent over backwards to try to figure out, to try to say, oh, this is actually empirical.
Some philosophers of biology have said, forget about it.
It's not empirical.
It's just a mathematical model.
It has application conditions.
But as a
Again, it's all very different than physical laws, because it does seem like something you could come up with from the armchair, right?
You didn't have to be Darwin doing the Beagle thing, right?
The problem is that when you couch natural selection as this universal thing, even if we assume it has standard empirical law content, it doesn't say anything specific.
There's no content, and it doesn't tell you what's fitter than anything else.
There's no predictions.
It does apply everywhere, but it's very generic.
It's like a schema.
And so we know that there are no traits that are always the fitter traits.
There's no evidence that evolution pushes towards certain kinds of traits as always being the fitter ones.
So sometimes being intelligent could be...
fitness enhancing and sometimes being stupid and just grazing on an easy food source can be fitness enhancing.
And it just totally depends on local environments.
