Question

How are primates different from all other mammals?

A) placental embryonic development
B) hairy bodies
C) arboreal lifestyles
D) ability to produce milk
E) opposable thumbs in many species

Answer 1

Primates are different from other mammals due to their arboreal lifestyles, larger brains, opposable thumbs, placental embryonic development, and ability to produce milk.

Step-by-step explanation:

Primates are different from all other mammals in several ways:

1. Arboreal Lifestyles: Primates have adaptations for climbing trees and swinging through branches. This includes features like rotating shoulder joints, widely separated thumbs and toes for gripping, and stereoscopic vision for depth perception.
2. Larger Brains: Primates have relatively larger brains compared to other mammals. This allows for higher cognitive abilities and complex social behavior.
3. Opposable Thumbs: Many primate species have opposable thumbs, which enable them to grasp and manipulate objects with precision.
4. Placental Embryonic Development: Like most mammals, primates have placental embryonic development. This means that a complex placenta connects the fetus to the mother, allowing for gas, fluid, and nutrient exchange.
5. Ability to Produce Milk: All primates have mammary glands that produce milk to nourish their young.
