Nature: Bro, it’s fine. All the other animals will think you’re smarter if you stand up straight. You’ll look really cool too, all tall and hairless and shit. Chicks love that stuff.
It’s not very true. Our bodies work fine for a good long time. It may be the cause of some of the problems we get as we age though
Incidentally I have heard (no idea whether it was folk stories or science) that kids who don’t crawl (some roll and drag themselves and learn to walk very early) get bad backs young
Most of the great apes are more or less upright much of the time

A horrible thought I heard once and can never get out of my mind:
Our bodies originally had horizontal spines and everything hung down from it. Now we hold our spines vertically, but the internals now all hang wrong.
No idea if true (seems like it’s simplifying eons of evolution), but it makes me very uncomfortable imagining it.

I also read that the human baby head is getting bigger while human hip bones are shrinking. Eww…
