I've read 2-3 books on them myself. They are the ancient people of Africa but, their myths would place their origins somewhere around the Mediterranean. I've read (somewhere?) that one anthropologist speculates that they are the leprachauns(sp) of Irish legend. They do have pointy ears, are reclusive and dance around fires all night, lol.
Wow! Did the antrhopoligist have any Khosian type skeletons from Europe (or from wherever the Celts came from) to back his hypothesis?
The Khosians also have some peculiarities in their sex organs. Another group from Irish legend, the Formorians, were presented as generally deformed. I wonder if that also could be an exaggeration of the Koho's peculiarities?
