As a matter of fact, I have the answer to your question. One of the scholars who has thoroughly researched the term negro, negroid (negro-like) is the great John G. Jackson. On page 230 of his classic "Introduction of African Civilizations" he states the following:

"Any word that can be used so ambiguously as "Negro" should be discarded, since for descriptive purposes it is totally devoid of meaning; but getting rid of this word is not going to be easy. That branch of the human race which may be described as black or dark brown is customarily labeled "Negroid", a word which means "Negro-like". If ""Negro" is disallowed then "Negroid" will soon follow it into oblivion, for if "the Negro" is a mythical concept, how can anything be likened to a nonexistent entity. The question naturally suggests itself that, if we get rid of the word "Negro," what will we put in its place? This is a fair question, and we have a suggestion to present. In ancient times black men were called "Ethiopians." Why cannot we today, following the usage of modern anthropology, refer to members of the Black race as "Ethiopoids", rather than "Negroids"?

One Love!
