However, I’m not sure how relevant it is. Covergent evolution is quite rare, when you consider all of evolutionary history. The last common ancestor of cephalopod and vertebrates (camera eye) was 750 mya and had a distinct photorecevier. A recent studies have shown a 70% similarity in the gene expression profile between octopus and human eye tissue. This suggests that they are not so convergent as commonly thought.

Simmons suggest that convergent evolution, is not only possible but likely, by tacking on an extra almost 3 Billion years to this time scale? I doubt that our genetic material and/or cell structure would even be the same, given this amount of time.
that list is broken, but I take your point.

Sounds like someone needs to check their priors.
