Etymology
Origin of homo1
First recorded in 1920–25; by shortening of homosexual ( def. )
Origin of Homo2
First recorded in 1590–1600; from Latin homō “man, human,” literally “the earthly one,” derivative of humus “earth, ground, soil”; related to Latin hūmānus “pertaining to man, human”; akin to Old English guma, Old Irish duine, Welsh dyn, Old Lithuanian žmuõ “human being”; see humus, human
Origin of homo-3
< Greek, combining form of homós one and the same; akin to Sanskrit sama-; see same
Explanation
The genus that includes modern humans is called Homo. "Homo sapiens" are modern humans. Our ancestors had names like "Homo neanderthalensis" and "Homo erectus." Homo is a Latin word that means man, or human. When it is used as a prefix, as in "homosexual," it comes from the Greek word homos, meaning the same. It is from the word "homosexual" that the noun homo is shortened and takes its second meaning — a derogatory term for a homosexual or gay man. Its use is offensive, and you should use other terms instead. It is spelled with a lowercase h in this use.
