 | | Though these works agree on the monophyly of each of the Atelidae, Pitheciidae, and Cebidae (Cebinae + Aotinae + Callitrichinae), they disagree on the relative relationships among the families. |
 | | Epsilon-globin and beta-2-microglobulin (both autosomal) infer a sister-relationship between the Atelidae and Pitheciidae; IRBP (autosomal) supports a clade of Pitheciidae and Cebidae; G6PD (X-chromosomal) groups the Atelidae with the Cebidae. |
 | | Such disagreement among molecular datasets is consistent with the hypothesis that an evolutionarily short internode separates the two divergence events giving rise to the progenitors of the platyrrhine families; the conflicting nuclear topologies would then be the result of differential lineage sorting at various genetic loci. |
