Early Primates Primarily Inhabited Cold and Temperate Climates, New Study Suggests

Primates historically transitioned across diverse climates: (A) transition between the temperate (top), arid (left), tropical (bottom), and cold (right), main climates, for all primates; arrow size represents the proportion of phylogenetic branches with the respective transitions; (B) climatic transitions for early primates, who were living between 65 and 47.8 million years ago; (C) climatic transitions for species that were living between 47.8 and 23.03 million years ago; (D) climatic transitions for species that were living from 23.03 million years ago to the present.

Textbooks often portray primates as originating, evolving, and dispersing exclusively within warm tropical forests. This tends to come from fossil evidence distributed across tropical latitudes. However, new research led by University of Reading suggests first primates most likely lived in North America in a cold climate with hot summers and freezing winters. Primates historically transitioned across diverse climates: (A) transition between the temperate...
