From: Identification, classification and evolution of Owl Monkeys (Aotus, Illiger 1811)
Proposed scenarios of Aotus evolution. Left: Tentative Aotus phylogeny as indicated by Dat-CON analyses based on 8 Aotus species herein analyzed. The presumptive positions of A. miconax, A. brumbacki and A. zonalis are based on biogeographic and karyotypic data [11, 15]. Diploid chromosome number (2n) is indicated. This arrangement requires at least two separate events accounting for red neck pelage. Right: Alternative polytomy resulting from collapsed branches. This arrangement also requires at least two separate events accounting for red neck pelage.
