Way back in reply 1082, tallhappy commented on the reptile-mammal transition series as follows:
Stuff like this is one of the reasosn people are quite rightly skeptical of evolution. So much of it has been junk science. (Ontogeny recapitulates phylogeny -- not even logical).
Taking this to be an interconnected whole, I countered as follows in reply 1091:
Please explain how "recapitulation" applies here. Where's the ontogeny?
(I had posted a figure comparing fossil skulls of Synapsids and early mammals.)
tallhappy later denied intending any connection between the fossil skulls and the "recapitulation" doctrine, except that he considered both examples of "junk science."
But it turns out there is a connection:
In 1837, a Creationist reported that during a pig's fetal development, part of the incipient jawbone detaches and becomes the little bones of the middle ear. After Evolution was invented, it was predicted that there would be a transitional fossil, of a reptile with a spare jaw joint right near its ear. A whole series of such fossils has since been found - the cynodont therapsids.Is Evolution Science?.
Lindsay isn't making it up. Modern anatomy labs still mention this.
A treatment of mammal and reptile jaw specializations, among other aspects of "What is a Mammal?".
Here's a history of vertebrates that closes with a reference to the ear bone migration in some professor's course notes.
I don't recall the link, but I'm glad it was so fruitful.
