A chimpanzee has evolved to the moment where it does primitive throwing
akin to what prehumans did some 8 million years ago. And like the
modern chimp, they were quadrapeds until the Throwing transformed their
quadrapedal motion into biped motion.

So the modern chimp follows the same pattern that was followed some 8
million years ago with our prehuman ancestors. Throwing created
bipedalism.

Thus, if this theory is correct then a correlation of the physical
extent of the femur groove of chimps compared to the Rotator Cuff of
chimps would be proportional to the human Rotator Cuff compared to the
human femur groove.

If bipedalism had arisen before throwing then the turnings and physical
support of the femur groove would have been proportionally larger than
the Rotator Cuff.

Understand that a *cuff* is the inverse of a *groove* but physical
testing of the strength and capacity of a groove to that of a cuff
implies origins. Chimps are not bipedal and so they lack a femur
groove, but chimps throw on occasion and chimps have a Rotator Cuff.

So the magnitude of the Rotator Cuff in humans is larger in proportion
to the turnings of the femur groove in humans and that is because
Throwing came first and created bipedalism millions of years
afterwards.
