Re: Afrotheria revisted
"Their long period of isolation in Africa, as assumed by molecular inferences,
now to be reconsidered in as much as Eocene paenungulates and elephant-shrews
are here found to be related to some Early Tertiary Euramerican "hyopsodontid
condylarths" (archaic hoofed mammals).
As a result, stem members of afrotherian clades are not strictly African but
Early Paleogene Holarctic mammals."
How can this be explained. Isn't there a contradiction here with the previously
findings about common ancestry of the Afrotheria? I mean, does this last part
AFAICT, all they're saying is that the biogeographic situation is more
complex than previously thought, right? I don't see why this shouldn't
be so ... even today there are non-African sirenians and
proboscideans, and until fairly recently there were a good deal more.
