Hamilton et al. (2001) suggested that the marine ancestors of Inia, subsequent to their divergence from Pontoporia, invaded freshwater ecosystems of Amazonia during eustatic sea - level highs of the middle Miocene, and evolved freshwater habits prior to the subsequent drop in eustatic sea - level late in the Neogene.
