I think he's making a point for evolution here since an octopus eye is clear evidence against a common designer.
The germ layer that the eyes are derived from differs from vertebrate eyes, being entirely ectoderm.
The eye is everse, not inverse.
The photoreceptors are rhabdomeric, not ciliar.
The photoreceptor protein is an r-opsin, not a c-opsin.
And yet it fulfills the same purpose as the vertebrate eye and is very similiar.
There's even a lineage of preserved invertebrate eyes that would show how such a complex assembly could arise from less complex designs.>>8291531
