I was wrong, some lemurs also have tapeta but, oddly, tarsiers don’t, in spite of having many more adaptations to low light.
What’s weird is that the advocate of the orc theory just throws in details without even considering whether they’re plausible. A full hair coat? Easy, we already have hair, and most of our “relatives” have full coats. Larger teeth? Sure. A gain of function that’s been lost to an entire phylum, including the apes he references? Unlikely.
