* Primates are a specific order of mammals. Just like there are orders like carnivores (cats, dogs), rodents (mice, rats), and cetaceans (whales, dolphins), primates are a distinct group.
* Primates share specific characteristics. These include grasping hands and feet, five-fingered hands, large brains relative to body size, and a tendency towards social behavior.
* Many mammals don't have these traits. Think of a dog, a cow, a bat, or a whale. They are mammals, but they lack the key features that define primates.
So, while all primates are mammals, not all mammals are primates!
