Thanks for mentioning that JS.

I should have mentioned that the PE version of rapid change still takes 100s of thousands, if not millions, of years.

It is very unusual to find fossils from the same series farther apart than a few thousand years but closer together than a few million. In addition, it is common for the distance between fossils to increase the farther back in time they initially formed.

I just like pointing out that we have observed selective breeding producing remarkable changes in morphology in fifty generations. If members of a species are separated by a physical barrier, the time required for the divided populations to diverge in physical form would be a geologic eyeblink, even assuming thousands of generations.

A lot of the odd physical forms we see are the result of sexual selection, which produces results as rapidly as breeding programs conducted by humans.
