Yes, the gaps that remain are what's left after several large gaps have been plugged. Each time a transitional fossil is found, and there have been many, the creationists are backed into a smaller and smaller corner.
The biggest -- and to me the best -- example is the hoary old claim of the creationists: "You haven't found the missing link!" This is important for two reasons: (a) creationists made their one big prediction that no intermediate (sub-human) species existed; and (b) evolution predicted that such must have existed, and that perhaps one day their fossils would be found. A perfect setup for the creationists to test their "scientific" theory.
But now that this one crucial cornerstone of creationism has been shattered (i.e. special creation of man with no intermediate species), they still won't give up. They never do; they never will. Prominent Hominid Fossils.
Creationists, for instance, are certain that Archaeopteryx is in no sense transitional, or indicative of any transition, between reptiles and birds. However some claim that it is not transitional because it is a reptile (with hoaxed feathers) whereas most claim it is not transitional because it is NOT a reptile, but simply a bird.
The archaic ceticean Basilosaurus has been identified both as just a whale and as a marine reptile, in this case (at different times, i.e. before versus after its rear limbs were discovered) by the same individual, creationist fossil "expert" Duane Gish!
Homo erectus, albeit different examples thereof, has been classified by creationists both as an ape and as a human.
Total garbage. The problem of the Cambrian explosion where over 40 new phyla (the highest order of classification next to kingdom) arose suddenly, without antecedents in less than 5 million years remains a completely unexplainable. Darwin himself admitted that if the antecedents were not found his theory would be false. Gould split with Darwinism because he saw that due to the lack of of ancestors for these numerous phyla, Darwinism had been disproven.
