Do humans have enough biological differences to be grouped into races or subspecies?

Humans have biological differences that can help group them into races or subspecies, just like how different types of dogs look and act differently.

Imagine you have a big box full of different kinds of cookies, chocolate chip, sugar, oatmeal, and peanut butter. Even though they’re all cookies, each one has its own taste and texture. In the same way, humans are all people, but we can have differences in our skin color, eye shape, or even how our hair grows.

Think about dogs, some are small like a chihuahua, and others are big like a Great Dane. They’re still all dogs, but they look different. People are kind of like that too. Some people might have darker skin, while others have lighter skin. Some might have curly hair, and others straight hair, just like some dogs have floppy ears and others have pointy ones.

These differences don’t mean one group is better or worse than another. They're just part of what makes us all unique, a little like how each cookie has its own special flavor!
