Natural selection is the combination of two ideas: 1. Population characteristics change over time if members of the population are systematically disallowed reproduction. 2. Nature systematically disallows reproduction.
I'm willing to accept that I'm suffering from hindsight bias. But will you at least give me that his theory is much easier to understand than any of the others? And maybe a few guesses on the topic of why it was so hard to think of?
Also, even if an insight is rare, that doesn't mean its bearer deserves credit. Many inventors made important accidental discoveries, and I imagine luck must have factored into Darwin's discovery somehow as well. If 1% of biologists who had gone on the voyage Darwin went on also would have developed the theory, does he still deserve to be on the list of the top ten intellectuals?
Addendum: Here is an argument that ancient scientists and mathematicians don't deserve as much credit as we give them: they were prolific. We have no modern equivalent of Euler or Gauss; John Von Neumann was called "the last of the great mathematicians". There are two possibilities here: either the ancient thinkers were smarter than we were, or their accomplishments were more important and less difficult than those of modern thinkers. The Flynn effect suggests that IQs are rising over time, so I'm inclined to believe that their accomplishments were genuinely less difficult.
And even if making new contributions to these fields isn't getting more difficult, surely you must grant that it must become more difficult at some point, assuming that to make a new contribution to a field you must understand all the concepts your contribution relies on, and all the concepts those concepts rely on, etc.

Extraordinarily so, yes -- it does astonish me that no one hit it before. Nonetheless, the empirical fact r...
Martial arts can be a good training to ensure your personal security, if you assume the worst about your tools and environment. If you expect to find yourself unarmed in a dark alley, or fighting hand to hand in a war, it makes sense. But most people do a lot better at ensuring their personal security by coordinating to live in peaceful societies and neighborhoods; they pay someone else to learn martial arts. Similarly, while "survivalists" plan and train to stay warm, dry, and fed given worst case assumptions about the world around them, most people achieve these goals by participating in a modern economy.
The martial arts metaphor for rationality training seems popular at this website, and most discussions here about how to believe the truth seem to assume an environmental worst case: how to figure out everything for yourself given fixed info and assuming the worst about other folks. In this context, a good rationality test is a publicly-visible personal test, applied to your personal beliefs when you are isolated from others' assistance and info.
I'm much more interested in how we can can join together to believe truth, and it actually seems easier to design institutions which achieve this end than to design institutions to test individual isolated general tendencies to discern truth. For example, with subsidized prediction markets, we can each specialize on the topics where we contribute best, relying on market consensus on all other topics. We don't each need to train to identify and fix each possible kind of bias; each bias can instead have specialists who look for where that bias appears and then correct it.
Perhaps martial-art-style rationality makes sense for isolated survivalist Einsteins forced by humanity's vast stunning cluelessness to single-handedly block the coming robot rampage. But for those of us who respect the opinions of enough others to want to work with them to find truth, it makes more sense to design and field institutions which give each person better incentives to update a common consensus.
