I think there’s an important distinction to make. He wasn’t proposing evolution in the modern Darwinian sense, where all forms arise through purely naturalistic processes from a common ancestor. Instead, his idea of the “vertebrate archetype” was a structural framework—an underlying pattern that different organisms instantiate in various ways.
So when early vertebrates like jawless fish appear, they can be understood (from Owen’s perspective) not as ancestors in a strictly genealogical sense, but as early expressions of a recurring anatomical pattern. That’s a different conceptual model from standard evolutionary accounts, even if there are points of overlap.
I think that’s fair to raise, but in this case the reference is more about continuity with Owen’s broader body of work. In On the Nature of Limbs, he doesn’t re-develop the full philosophical background because he had already done that elsewhere—particularly in his earlier discussions of archetypes, which were influenced by Platonic and idealist traditions. The lecture builds on that foundation rather than restating it in full.
And Yes, I read at least of his works, but it was not cover to cover.
Skeptics, such as Talkorigins, have claimed for years that Genesis has gotten the creation order wrong because, at the time, land plants came after sea animals appeared. http://www.talkorigins.org/indexcc/CH/CH801.html
For example, the timing of early photosynthetic life has been revised significantly over time. Earlier models placed key developments later, while more recent work has pushed some of these events further back [1,2].

In Psalm 8 6–8, you get:
“You made him ruler over the works of your hands…
the sheep and oxen…
the birds of the heavens…
and the fish of the sea,
whatever passes through the paths of the seas.”
Compare that with Genesis 1:26:
“Let them rule over the fish of the sea, the birds of the heavens, and the livestock…”
