>Einstein made a tremendous contribution to a tower that was already quite tall, while Darwin's contribution was to the ground floor where everybody could get on.

I see your point, but if Darwin created a new field but Einstein contributed to an existing field, Darwin ought to be considered a greater genius. (Personally, I think it is better not to define anyone as a genius so that we can continue to evaluate their work critically.)

I'm saying that we value things we don't understand more than things we do understand.
