[Taxacom] Primate {twadle?}

Ken, none of this comes across as 'serious research findings' - just a
whole series of fabrications.

Fabrication 1. "South America and Africa have been separated since the
early Late Cretaceous, so vicariance of primates does not appear reasonable
as an explanation for their appearance in the Eocene on two continents
separated by the Atlantic." Twaddle. There is no evidence that they
'appeared' in the Eocene. None at all. I dare you to specify any such
empirical evidence. Of course any alternative is 'unreasonable' by
definition.

Fabrication 2. "with rafting across the Atlantic usually considered a
feasible way for how primates arrived in South America, presuming they
originated in Africa" - make me a raft. Any raft at all. Another fantasy.

Fabrication 3. " similar means of arrival in South America has often been
proposed for the hystricognath rodents, the dispersal of amphisbaenian and
gekkotan lizards, and the Opisthocomiforme" Oh yes, everyone says it is so,
so it must be true. Really true. Saw a lot of this in our recent elections.

Fabrication 4. "... the re-established, relatively contemporaneous first
appearance datum of primates and rodents in South America leads to
consideration of possible similarities of intercontinental dispersal
mechanisms for the two mammalian groups." Leads to nothing of the sort.
Total garbage. This is just literalist reading of the fossil record as a
sign of migration.

Cheers,

John Grehan
