What organisms walk on two legs?

Humans are organisms that walk on two legs.

Imagine you're playing with your favorite toy, maybe a doll or a stuffed animal, and it stands up straight like you do. That’s how humans move around! We use our legs, which are like strong, bendy sticks attached to our body, to help us walk. Each time we take a step, one leg moves forward while the other stays behind, just like when you walk from your bed to the kitchen for breakfast.

• Humans have two legs, not four like dogs or cats.
• We use our arms and hands to help us balance or grab things while we walk.
• Our backbone helps us stay upright, just like a ruler keeps your drawing straight!

Other animals that walk on two legs are called bipeds, like some dinosaurs and even birds when they're walking around. But the most famous biped is you, because you can walk, run, jump, and even dance!
