Fascinating. Utterly fascinating.
instead of calibrating the time- course of evolution with a scanty
fossil record, the geographical boundaries of the main molecular
clades of primates are calibrated here with radiometrically dated
Stupid. Utterly stupid.
And a failure of peer review.
This indicates that primates originated when a
globally widespread ancestor (early Archonta) differentiated into a
northern group (Plesiadapiformes, extinct), a southern group
(Primates), and two south-east Asian groups (Dermoptera and
Scandentia). The division occurred with the breakup of Pangea in the
Early Jurassic and the opening of the central Atlantic (~185 Ma).
What next? A Cryogenian origin for crown-group rabbits?
