There is one remaining issue to address, which is palynology, the science of fossil pollen.
All orders and families of the angiosperms appear abruptly in the fossil record (the same for most lower systematic categories).
Darwin’s “abominable mystery” is not only very much alive and kicking, but it also suggests intelligent design.
This year a new article by Silvestro et al. (2021), “Fossil data support a pre-Cretaceous origin of flowering plants,” was published.
There is clearly a pattern of discontinuities that requires an adequate explanation, and Darwinism is not it.
