Primates Evolved in Cold Regions

New evidence from fossil spore and pollen records suggests early primates originated in North America under seasonally cold conditions, not in tropical climates as long assumed. Some lineages even reached Arctic latitudes and may have survived winters via torpor or hibernation, similar to modern dwarf lemurs. — It shows how present‑day distributions can mislead scientific narratives, and that climate and seasonality were powerful drivers of primate adaptation and mobility.
