fossil evidence exists of evolution in chains containing hundreds of intermediate fossils. Of course the more elements in the chain of fossils, the more "gaps" there are, giving you something to gripe about.
Yet nevertheless the more fossils turn up, the more they support evolution.
One of the primary ways that evolution would be falsifiable is if the fossil record were incoherent, jumping around from species to species with apparent irregularity. But that isn't what is found.
Should the discovery institute really desire to do science, then demonstrating the randomness of species would be a way to falsify evolution. Yet they don't even bring up the subject.
Eureka! You have actual hard information supporting missing fossil links? Please post me some links to these "missing" fossil links so that I can "humbly" eat a healthy portion of crow!
