Mitochondrial DNA analysis suggests that founder‐event speciation played a key role in the divergence between cis‐Andean and trans‐Andean clades, as well as in the diversification of cis‐Andean lineages. Ancestral range reconstruction using mitochondrial genomes indicates that the most recent common ancestor of Alouatta had a widespread distribution ...
