Summary

TLDRIn this video, the differences between New World and Old World monkeys are explored, focusing on physical appearance, behavior, diet, and evolutionary distinctions. New World monkeys, found in Central and South America, have broad, flat noses and prehensile tails, while Old World monkeys from Africa and Asia have narrow, downward-facing nostrils and lack prehensile tails. The video also highlights their varying diets and dental formulas—New World monkeys have 36 teeth, while Old World monkeys have 32. The video emphasizes the evolutionary significance of these differences, offering insight into the diversity and evolution of primates.

Takeaways

😀 New World monkeys have broad, flat noses with nostrils that open to the side, while Old World monkeys have narrow, downward-facing nostrils.
