you wouldn't be able to bend your back
back bones help a cheetah run they cant get far when they dont have back bones. and as you know cheetahs are ONE of the fastest creatures on the planet so if they did'nt have back bones i would not have said that.
A single, long bone would be rigid, to make a spine that will bend it has to be made of smaller articulated units.
The scapula is one single bone. You have one on either side of your upper back.
you have to make the bones spell ten
It would make sense...

do bunnies have back bones

That would depend on who "they" happened to be.
they dont have back bones they dont have back bones they dont have back bones they dont have back bones
