“The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”
