General KnOWLedge: Why do humans walk on two legs?

Why aren't we four-legged like so many of our furry friends?

Humans are bipedal. This means we get around on two legs. Which is fine until ...

you look around at all of the other mammals in the world and realize that they are all quadrupeds, or four-legged movers. Speedy cheetahs, mighty elephants, agile deer, and gentle mice. Even monkeys and apes are able to split time between being upright and four-limbed climbers and wanderers.

Given that all animals evolve, or change over time, in a way that best suits their survival, why did our ancestors end up choosing two legs over four? How did that help humans on their journey to the present day?

Step by step

In the second episode of this season of OWLconnected's General KnOWLedge, we're going to answer just that.

Putting one foot in front of the other, we'll walk you through the advantages and disadvantages of being a two-legged creature, as well as the top theories on how we came to walk this way.
