There have certainly been many human species (take a look at the Wikipedia page on human
), and some of them were contemporaneous.
'Species' is a word whose definition is highly arguable. The common-or-garden definition is a population capable of successful interbreeding. Still,
we tend to regard Homo sapiens
and Neanderthals as different species in spite of interbreeding, so it's a grey area.
If there were contemporaneous human species that could not interbreed at any time in prehistory, but whose ranges in space and time nevertheless
overlapped, and if all were intelligent to some degree, then I am certain they would have competed with one another, and one lot would eventually have
wiped out all the rest. If they could
interbreed, then they would probably be subsumed rather than literally exterminated.
But it is more likely they were isolated from each other, and died out without meeting their intelligent contemporaries. That's what happened to
, by all accounts.
Exciting to think that deadly confrontations between intelligent species was part of Earth's history. I have often wondered whether the myth of Cain
and Abel encodes the story of our elimination of a cousin species. Perhaps this is also the root of the notion of original sin. I am glad to live in
an era when the dominance of H. sapiens
