Humans have back problems because we took a spine that had evolved for billions of years to be horizontal and stacked it up like a bunch of dinner plates.
Don’t discount the power of sitting too much with bad posture. The spine can stay totally fine up to a significant age … if you’re not sitting like you’re cosplaying as the Hunchback of Notre-Dame and get up and move once in a while.
Bipedal dinosaurs with grasping hands are pretty common. Velociraptors, for example.

I read this while I’m sitting, hunched over, on an ice pack, at physical therapy for sciatica.
Thank you for the reminder.
I think the T-rex did it first.
