What say you, while you have a coccyx
I propose that you are reading from poor sources.
Have yours removed and get back to us with any improved sitting or balancing. Oh, you need to find
some structure
for these ligaments to attach or you faw' down. One of the attached ligaments keeps a nearby orifice closed. Removal = Yuk.
and useless ear wiggling muscles
Communication is good in all forms.
Ears need to attach to something.
and a little muscle for lifting each hair attached to it
Would you like to moisturize your skin 24/7? The hair muscles flex the hair and this pumps oil to the skin surface from a gland near the muscle base. That's why
all skin has this muscle, gland, and hair feature, even "hairless" skin.
and a broken vitamin c gene shared with other primates
and guinea pigs and bats. My sister squeals like a guinea pig. That clinches it.
and having had a weak, useless grasping reflex once as an infant,
A
handful of newborn reflexes promote bonding with parents and are not valuable for climbing money bars, fist fighting, or arm wrestling.
and having the weird loop in the nerve that goes from the brain to the larynx, taking a detour all the way down to the heart and back up again?
If this is a problem, why can I not find mention of "the problem" when doctors reconstruct the entire nerve?

During early development, when the body is more of a sphere, the nerves are routed, with some crisscrossing. As the body elongates into an oval shape, in order for the nerves to remain functioning some get stretched with the heart and lungs. Surgery could shorten the distance (I don't see that they do) but the interior is pretty well protected and the left and right nerve are balanced and function fine.
Growing a nerve longer is not a problem or a drain on resources or a danger.
The longer routed nerve
does connect to a number of other organs along the way though.
