This brief review summarizes new paleontological and molecular data that together support
a late middle Eocene Afro‐Arabian origin for crown Lorisiformes. Phylogenetic analysis …

New World primates comprise a diverse group of neotropical mammals that suddenly
appeared in the Late Oligocene deposits of South America at around 26 million years ago …

Revised age estimates for the primate-bearing localities of the Jebel Qatrani Formation
(Fayum area, northern Egypt) have provided a new perspective on primate response to early …

In two areas of phylogenetics, contrary predictions have been developed and maintained for
character analysis and weighting. With regard to adaptation, many have argued that …

The ontogeny of the nasolacrimal ducts (NLD) and canals (NLC) are investigated in
strepsirrhine and haplorhine primates. Developmental series of serially sectioned fetal …

It has long been accepted that the adaptive radiation of modern placental mammals, like that
of modern birds, did not begin until after the Cretaceous/Tertiary (K/T) boundary 65 million …

Aim We investigate the hypothesis that it was the capacity for torpor or hibernation that
enabled the lemuriforms (and possibly other mammal groups, eg tenrecs and rodents) to …

The known fossil record for undoubted primates of modern aspect (ie, confined to
Euprimates and excluding Plesiadapiformes) dates back to the beginning of the Eocene …

Background Because rates of evolution and species divergence times cannot be estimated
directly from molecular data, all current dating methods require that specific assumptions be …

Change in body mass with time has been considered for many clades, often with reference
to Cope's rule, which predicts a tendency to increase in body size. A more general rule …
