YouTube video: Dr Polaris looks at the earliest primate and plesiadapiformes

A YouTube video
by Dr Polaris once again confuses the traditional ‘connection’ between early primates and early plesiadapiformes.

There is no pylogenetic connection. Any similarities are due to convergence.

My comments
A few corrections:

1. @1:55 Flying lemurs (Dermoptera ) are lemurs = primates. Indri is near the last common ancestor.
2. Scandentia, Lagomorpha and Rodentia are not related to primates, but represent part of a second origin of the placenta close to multituberculates and plesiadapiformes. So Euarchontogliries is not a monophyletic clade.
3. Missing from your chart are bats, which arise from the smallest primate, Microcebus.
4. Genetic ‘clades’ like Afrotheria are not supported by trait analyses that include fossil taxa, always missing from genetic studies.
5. Traditional Xenarthra are actually two clades with long, tubular rostra (armadillos) arising separately from short deep rostra (glyptodonts and sloths).
6. Birds diversified during the Mesozoic. That’s why we have terror birds in South America arising from secretary birds in Africa and why we have penguins in the earliest Cenozoic and geese (Asterornis) in the Latest Cretaceous.
7. Don’t trust molecular evidence. It can be contaminated in deep time studies by viruses. Trait analysis includes fossils and gets down to the tiniest details.
8. The Last Common Ancestor (LCA) of primates was similar to Notharctus and Kopidodon with the extant coatimundi, Nasua, a close outgroup according to trait studies.
9. @5:16 those ‘weird multicusped upper incisors’ are just transitional from apatemyids to multituberculates and rodents (so not related to primates).
10. @7:38 you wondered about the earliest age of plesiadapiformes. In analysis they precede multituberculates, which are known throughout the Jurassic.
11. @12:05 you report “it is still unclear” how plesiadapiformes are related to primates. That’s because they are not related. See the large reptile tree at ReptileEvolution online.

Dr. Polaris, you might want to ditch the textbooks, which are out of date, and run your own analysis, in order to avoid promoting traditional myths. All it takes is a fascination with the subject matter, which you admirably display.
