Re: A Wild Hare [not dino related]

Quoting david peters <davidrpeters@earthlink.net>:


Are flying foxes really primates?

Short answer: No.

Long answer: Recent molecular studies have thoroughly refuted the hypothesis that bats are diphyletic, with megabats closer to primates. Last I heard, molecular evidence was even indicating that Microchiroptera is actually paraphyletic with respect to Megachiroptera, and that bats are on a totally different branch (no pun intended) from primates on the placental tree (hanging out with shrews, true ungulates, carnivores, and pangolins).

In the above paper is a ref [not copied] for some soft-tissue
cladistic work describing a close association between lagomorphs and primates.

Interesting. Molecular evidence also indicates that rabbits + rodents are close to primates + tree shrews + colugos.

1. Do eurymlids have a large diastema like Gomphos, lagomorphs and rodents do?

Not familiar with them.

2. I know that a basal primate, Plesiadapis, has a large diastema, among other interesting characters.

May not be a primate; possibly closer to dermapterans, though (AFAIK) still an archontan.

3. Did the two large diastemas, so close to each other on the tree, develop convergently? Or is there another connection?

And in a worst-case scenario, wouldn't that be weird?

Not really. Highly related to food processing; diastemata appear to have arisen many times among mammals.
