Abstract excerpt

Amazonia has undergone significant geological and climatic changes over millions of years, shaping its rich biodiversity. However, the impact of historical environmental change on driving species diversification remains debated. Two-toed sloths (genus Choloepus) provide a valuable model for studying this connection due to their wide distribution across Amazonia and their restricted arboreal lifestyle, which makes...
