The origins and the divergence times of the most basal lineages within primates have been
difficult to resolve mainly due to the incomplete sampling of early fossil taxa. The main …

Throughout the world, closely related species are found on landmasses separated by wide
stretches of ocean. What explains these far-flung distributions? Why are such species found …

In primates, feedforward visual pathways from retina to lateral geniculate nucleus (LGN) are
segregated to different layers. These layers also receive strong reciprocal feedback …

Although advanced anthropoid primates (ie, Simiiformes) are recorded at the end of the
Eocene in North Africa (Proteopithecidae, Parapithecidae, and Oligopithecidae), the origin …

The Fayum Depression of Egypt has produced a great diversity of fossil material, including
marine and freshwater fishes. In contrast to the Eocene formations of the Fayum, the …

Quantitative analysis of morphology allows for identification of subtle evolutionary patterns
or convergences in anatomy that can aid ecological reconstructions of extinct taxa. This …
