This might be a really weird question, but why do Kangaroos jump instead of walk?
As a human jumping takes a lot more energy than jumping, so it must be something biological, but they are like the only animal family that does that (I’m sure there are more kangaroo-like animals I don’t know about)?
Edit – After seeing a few comments, this post isn’t about why the evolved to do so (even though it is an interesting question), I was asking what is the anatomical reasoning for it.

Hopping is much more efficient than walking, they have anotomically evolved to gave two giant springs for legs that propel them forward with minimal use of energy. I did hear that they are the most efficient movers in the animal world when considering energy spent.
I’ve also heard humans move more efficiently while skipping rather than walking/running. I don’t remember where I heard that but I do like the idea of our ancient ancestors skipping about all day looking for a feed.
