do black people have an extra muscle in their leg?

yes. its in their butt. high twitch fiber muscles

Why do white people have a phobia about asking a harmless genetic question regarding muscle mass in blacks. White paranoia due to pop culture an television propaganda has made their comensense evaporate. You are not a drone that has too viscerally reject a question, simply because it calls upon recognizing a difference in traits of blacks.. White people are very very different then blacks, in many many visible and not so visible ways. We do not (all) have the same color ,eyes, hair, and in many cases shaped lips. To deny obvious differences is dangerous and irrational and you should examine it. If the mare question causes you too call others rude names like racist. You are the simpleton not those that say what thay honestly see, think, and want to investigate. Get it?

nope all the same like any other human being

No the only thing different about them is their skin.....

no?
