"If I ask you who is the most famous scientist who ever lived, or the greatest scientist who ever lived you'll say either Einstein or Newton or something like that because their claims were supposed to apply universally. But the claim of somebody who is studying a particular feature of the evolutionary process like whether it's very fast or very slow, or occurs in steps and so on, that's not a universal claim, that's a rather specialised claim and so you can't claim to great fame and great success."
