This article is too long to post the whole text, but its very interesting. These flat faced humans have very powerful jaws and its speculated that they ate nuts and lived alongside.. and compatibly with other groups. http://news.nationalgeographic.com/...ossils-homo-nature-science-meave-leakey-flat/ Flat-Faced Early Humans ConfirmedLived Among Other Human Species Until now, the fossil speciesstill nameless"has always been an enigma." August 8, 2012 New fossils recast a flat-faced oddity as a star species in the first chapter of the human storyperhaps even as our oldest known truly human ancestor. At the least, the fossils confirm that at least three different human species inhabited the same Kenyan neighborhood at the dawn of humanity, according to a new study led by paleontologists Meave and Louise Leakey. (Related: "Human Ancestor May Put Twist in Origin Story, New Studies Say.") Consisting of a face, a complete lower jaw, and part of a second jaw, the new fossils were found east of Kenya's Lake Turkana between 2007 and 2009. The products of a 40-year search, they provide the needed evidence to confirm that a disputed skull found in 1972 does in fact represent a new species, the team says. Dated to between 1.78 and 1.95 million years ago, the remains were uncovered within six miles (ten kilometers) of the 1972 skull, which was discovered by Meave Leakey's husband, paleoanthropologist Richard Leakey. continued.. And here is a graphic to a possible human family tree. http://ngm.nationalgeographic.com/2011/08/malapa-fossils/lineage-graphic
The old tree beings to take on an almost tropiary appearance, doesn't it? Of course, we are then stuck with the question as to whether any of the newly-recognized species were cross-fertile. (Oops! I know that that is going to make a few Nazis' lives more difficut that they can deal with.)
I would agree. Neanderthal's were, and they were quite different from us. As long as they were hominid and had 46 chromosomes, I figure they were cross fertile.
So two wierd-looking but cross-fertile bands meet. One band is unusually good-looking. The other are sort of blah-looking. One reject male and one reject female from both bands meet and decide that this is the best they're going to do. What do the kids look like? Chances are they would be marginally better-looking, although it may take some time for them to pair off with someone who will add something aestheticly worthwhile to the next iteration of their genes.
Which is probably why you don't want to get it. You cross someone who looks like Yaphet Kotto with a neanderthalensis female, you would probably get a child who looks like Whoopi Goldberg. You don't think that is a step up?
I disagree completely that if you cross Yaphet Kotto with a neanderthal you would get Whoopi Goldberg. The defining facial features of a neaderthal is a prominent brow ridge and a receding chin. Whoopi has neither.
The point is that you would get less of the more highly-specialized adaptations and a more generalized individual.
I think rape would have to be involved for a Neanderthal cross. Do you think Whoopi would be strong enough?
