Denton isn't out of date; he was always wrong. Yes, the gaps are filling in. Naysaying zealots find ways not to see or understand.
I'm going to save some typing and put inline from that link some of my exchange with an earlier clone of you.
Now, almost all of the data you have been reviewing were unknown in Darwin's day. For all the evidence that they did have, there were a lot of holes. Darwin et al. fearlessly predicted based upon the already-outlined tree of life that certain kinds of "intermediates" would be found. Precambrian life of any sort, legged whales, legged sirenians, ape-human intermediates, etc. Other intermediates, amphibian-bird mixes for instance, violate the presumed evolutionary scenario and are not predicted.This prediction is a certain kind of inference. Creationists who believed that God on certain days created certain "kinds" scoffed then and denied that such an inference from the then-available data was valid at all. They began to mockingly ask for "the missing link," which is exactly how you, who bill yourself as a scientist, opened the discussion.
The history since then has filled in gap after gap in the areas where evolution says the intermediates have to have existed. The people who will not make certain inferences because God will burn them in Hell for so doing still will not make them. Nevertheless, the ground under their feet has shrunk to nothing compared to the situation in 1859.
You darwinites always want to talk about God. Have you checked the updated horse evolution theory?
