Nosey, what's to bolster? The cases presented by evos are so minuscale in scope that if everyone single one of them were considered true, that the evidence as a whole would still disprove the gradualistic models of mainstream evolution.
We don't see them is a pretty straighforward comment. The fossil record does not record "the common ancestor": to my knowledge ever.
Same with living biota. You continually see the claim that, say, all such and such species evolved from a common ancestor, but we never see the common transitional ancestor. We don't see that for whales.
What is the common whale ancestor, for example, for the 2 main types of whales?
Basilosaurus is not considered a direct ancestor. What creature was?
This is repeated over and over again.
The fossil record just records abrupt changes and stasis. When we do see fine-grained changes, it is not from one whole type of creature into something remarkably different, but mere varities of the same species, and often we see a range where the species evolves into one direction only to evolve back, showing a conservatism within evolution that is the exact opposite of what is required to produce macro-evolution.
We just flat out have absolutely no evidence for gradualistic evolution in the fossil record whatsoever. We have no proposed transitionals with the previous, say, 10 species and the proceeding 10 species, or even a significant percentage of them present in the fossil record, and most tellingly, we also don't see that among living biota.
You could argue fossil rarity if living biota demonstrated something different, but it doesn't, and even arguing fossil rarity is an unsubstantiated claim.
If you are saying the intermediates are present, then please show them. Show, say, a series of 10-15, or at least most present, so we can see how one species gradually morphed into a different genera or family or order.
