Is it ever “settled”?
As things stand today, Darwin’s notion of evolution, especially when we extend it with the things we’ve learned in the intervening 160 or so years, has stood up very well to attempts to falsify it.
That’s what science as a process really is: that process of observing, proposing explanations, and then trying to knock those explanations down. Eventually, you have only a few explanations left standing: our best explanations for what we observe in the real world. It’s that collection of best explanations that we call “science.”
What isn’t science is (e.g.) climate models, particularly when they can’t even hindcast.
“Settled science” is a newspeak phrase that the Left has come up with to impose their policy preferences on us.

Why biology students have misconceptions about science.
I think there’s more of a crisis in science education (as with all education) than most people realize.
