During the Eocene epoch, (55-35 mya), primates, similar to lemurs, emerge in the northern hemisphere during a period of global warming to secure daytime openings in the food-chain. * Then in the following epoch, the Oligocene (~35-22 mya), the presence of these prosimian primates fades in the less-forested areas throughout the world as the overall climate cooled, but they continue to exist in Africa.  During the next epoch, the Miocene (23-5 mya), the climate cooled further and forests declined.
