It's the reason we have so many birth complications. Why do you think we are the only animal on the planet that is bipedal all the time? It's actually really mind bending how we survived and thrived

[-] IonAddis@lemmy.world 60 points 8 months ago

Technically...birds are bipedal all the time. They went about it very differently though.

[-] rockerface@lemm.ee 8 points 8 months ago

Birds have optimized for minimum weight tho, so they can afford to only have 2 limbs supporting the entire body

[-] EddoWagt@feddit.nl 6 points 8 months ago

Have you seen their legs though? They dont look sufficient at all, especially taller birds which stand in the water often have insanely thin legs

[-] rockerface@lemm.ee 4 points 8 months ago

Keep in mind that most of the bird's visible body volume is just fluff

[-] Soggy@lemmy.world 1 points 8 months ago

Birds like egrets and herons rarely weigh more than a few pounds. Even the red-crowned crane, a five foot tall bird, caps out at about twenty pounds. An average nine-month-old human weighs that but is only a foot and a half tall. Flighted birds are crazy light.

Wow, that is indeed crazy. I knew birds were light, but that's still impressive

[-] CitizenKong@lemmy.world 5 points 8 months ago

They're also dinosaurs, so definitely not mammals.

[-] K0W4LSK1@lemmy.dbzer0.com 2 points 8 months ago

haha got me there should have said mammals

We are just too stubborn to die out.

[-] peopleproblems@lemmy.world 8 points 8 months ago

Figured out the one trick Nature didn't want you know - evolution can be circumvented by sheer ignorant willpower.

[-] rockerface@lemm.ee 9 points 8 months ago

Not only we're the only bipedal mammal, we have the biggest head relative to our body out of any animal. That combination is just not a good time for anyone involved
