 The term 'black' in the united states, as described on this page, is a term that arose as an alternative to other terms which fell out of favor.  The etymology, therefore, as I pointed out in my first entry on this talk page, is an unbroken chain from a biological description.  You cannot meaningfully discuss the term 'black' in North American context without understanding its biological basis.  I repeat, this page should not exist if that connection cannot be made plain.
