. How important was Steve's determination and vision? Wallace came up with the theory of evolution too, and was an instigator for Darwin's ideas, but who knows who he was? What do you think is more valuable, Wallace's notes, or Darwin's notes from the Beagle? Wallace may have been the better scientist, but that doesn't make his artifacts more valuable. Darwin's reputation survived. That makes what remains of him more "valuable" than what survives of Wallace.
