Yes.....yes they have.....somebody hasn't been to college yet I see.

Example: Prof. Steve Jones of University College London published an updated version of Darwin’s Origin of Species in 1999, the fossil record still posed the same problem that Darwin saw in his own work... It said "The fossil record - in defiance of Darwin's whole idea of gradual change - often makes great leaps from one form to the next. Far from the display of intermediates to be expected from slow advance through natural selection many species appear without warning, persist in fixed form and disappear, leaving no descendants. Geology assuredly does not reveal any finely graduated organic chain, and this is the most obvious and gravest objection which can be urged against the theory of evolution.” (Almost Like a Whale, p. 252)
