The Greatest scientific discovery of all times (but naming no names!)
The blunt fact is that some of what we say in evolutionary biology, especially when dumbed-down for public or textbook consumption is also bunk. The proliferation of Just-So stories in evolutionary biology, even at the highest level, is extensive and well-known. So we're told confidently such things as that our body parts evolved 'for' such-and-such a purpose, and our physiological responses were selected 'for' a reason, and we have genes 'for' all of it.
In fact, anything that's here today can be given such explanations with little in the way of constraint much less testability. Nice, tight stories sell big!
Humility should have a deeper role in science and among us members of the Science-tribe. It seems unassailably true that life today is the result of a history. Darwinian selection also seems undeniably important, though there are other equally important evolutionary forces. And, humans really did come from terrestrial ancestors. We might hope to discover something that refutes such ideas, because it would be so energizing and exciting for science and the public alike! Alas, nothing suggests it will happen.
Still, who knows how much we don't know about life? What factors or forces might be as yet undiscovered but have an effect on biological change? What kind of real 'dark matter', that today is to us what, say, electrons or infra-red radiation were to Aristotle--or real dark matter to astronomists?
When we discuss the evidence for 'evolution', we should be humble enough to acknowledge that that word isn't so clear as it may seem. There are gaps in what we know, gaps in the fossil record, gaps in our theory (e.g., of how to predict phenotypes from complex genotypes, which we assume are causally connected, or how species evolve, or how to know when selection is acting, rather than drift).
We can't let Creationists cower us into asserting more than we know, or simply adopting a party line, as that would be a kind of victory of non-knowledge over knowledge. What sends us to work every day is the pursuit of what we don't yet know. There is likely to be a lot of that out there. It is hard to imagine something that would be so profound as to change our basic view of life as the product of historical evolution, much less anything that could convert us to a theologically literalist view. But we might discover things as new and exciting as the awareness that Darwin and Wallace brought to us about the nature of life. We should remain open to that possibility.
In fact, many scientists are atheists, some (naming no names!) so aggressively so that it is their way of hyping themselves and rolling in the book-sales and TV appearances. Of course, proving a negative is difficult, but science is not likely to prove, using its current set of principles, that God does not exist (even if He was just kidding about a 7-day creation). Many scientists are proud of their atheism, but let's not be hypocrites. And here is a warning to Creationists, who like to trash scientists for their views:
It is hard to imagine a scientist who would not crave being the one who discovered and could truly prove that the source of our hopes and dreams (naming no names!) really does exist. As the scientific discoverer of God, such a scientist would become the most distinguished human being in the history of our species. Darwin would be a puny dustman by comparison. The reason scientists don't take much to religious arguments is not that they'd not like to show them to be true, but simply, and perhaps sadly, because the evidence doesn't suggest that such a thing is even worth pursuing in science.
