Primate Duplicate Genes

Small fragments of DNA called core duplicons replicated and spread across the chromosomes of select primates between 8 million and 12 million years ago, a genetic characteristic not found in other animals and an evolutionary trait that may have "seeded" chromosomal development and fundamentally influenced human evolution and brain size.

Tarsiers Call in Ultrasound

New research has discovered that Philippine tarsiers (Tarsius syrichta) are the only primate species and one of the few mammal species to communicate using purely ultrasonic calls, vocalizing at 70 kHz to 90 kHz and well beyond the range of human hearing.

New Species of Monkey

A new species of primate, as yet unnamed but of the Callicebus genus that includes the titi monkey, was recently discovered in the Mato Grosso State, one of the last unexplored areas of Brazil.

New Snub-Nosed Monkey
