Haplorhines are a group of primates that include monkeys, apes, and humans. They are characterized by their dry noses and larger brains compared to other primates. This group is divided into two main categories: tarsiers and simians, which include both New World monkeys and Old World monkeys. These primates are known for their social behaviors and complex communication skills. Haplorhines typically have forward-facing eyes, which provide better depth perception, making them excellent at navigating their environments. Their adaptations have allowed them to thrive in various habitats around the world, from tropical forests to urban areas.
