Evolution and Paleontology Studies

The Q- and G-band analyses of Cebus capucinus , Cebus albifrons and Cebus apella are presented. The study is based on the results obtained from 18 specimens of the genus. For almost all of them, their exact locality is known. The data presented include the statement of two natural hybrids from C. capucinus and C. albifrons . On an evolutionary basis our results agree with the taxonomic concepts which postulate more similarity between C. capucinus and C. albifrons than between C. capucinus and C. apella . Furthermore, the comparative study of the Q- and G-band patterns indicates an independent chromosome evolution for C. albifrons and C. apella derived from a common ancestor more similar to C. capucinus .
