Quote:Cro Magnons arrived on this planet fully formed
If this is so, how come it is demonstrably the case that neanderthals, and all other hominids are related to cro-magnons? If humans just came from space, or spontaneously generated or whatever it is you suggest, howcome
Quote:Neanderthals and modern humans share about 99.5% of their DNA
(http://en.wikipedia.org/wiki/Neanderthal)?
Howcome Neanderthals and humans could also interbreed (today, 4-5% of the DNA of non-Africans is of Neanderthal origin)? As we know, there can be no cross breeding across genera, which is what you are suggesting humans and neanderthals are - different genera.
Genes/DNA in common between apes, hominids, and humans should be viewed as same or similar low-level genetic parts used for unrelated projects by some original designer(s). Similarly, you will find the same low-level C language math functions used in banking software and rocket telemetry software. That does not indicate that all telemetry software is hacked from banking software.
As far as humans being able to interbreed with Neanderthals (or any other hominid for that matter), all available evidence says it never happened and Paabo's claims that you can make such as case based on genetic similarities is not supported by anything in the real world.
The best description of the problem remains James Shreeve's article from 95:

Humans love to mate. They mate all the time, by night and by day, through all the phases of the female’s reproductive cycle. Given the opportunity, humans throughout the world will mate with any other human. The barriers between races and cultures, so cruelly evident in other respects, melt away when sex is at stake. Cortés began the systematic annihilation of the Aztec people--but that did not stop him from taking an Aztec princess for his wife. Blacks have been treated with contempt by whites in America since they were first forced into slavery, but some 20 percent of the genes in a typical African American are white. Consider James Cook’s voyages in the Pacific in the eighteenth century. Cook’s men would come to some distant land, and lining the shore were all these very bizarre-looking human beings with spears, long jaws, browridges, archeologist Clive Gamble of Southampton University in England told me. God, how odd it must have seemed to them. But that didn’t stop the Cook crew from making a lot of little Cooklets.
Project this universal human behavior back into the Middle Paleolithic. When Neanderthals and modern humans came into contact in the Levant, they would have interbred, no matter how strange they might initially have seemed to each other. If their cohabitation stretched over tens of thousands of years, the fossils should show a convergence through time toward a single morphological pattern, or at least some swapping of traits back and forth.
But the evidence just isn’t there, not if the TL and ESR dates are correct. Instead the Neanderthals stay staunchly themselves. In fact, according to some recent ESR dates, the least Neanderthalish among them is also the oldest. The full Neanderthal pattern is carved deep at the Kebara cave, around 60,000 years ago. The moderns, meanwhile, arrive very early at Qafzeh and Skhul and never lose their modern aspect. Certainly, it is possible that at any moment new fossils will be revealed that conclusively demonstrate the emergence of a Neandermod lineage. From the evidence in hand, however, the most likely conclusion is that Neanderthals and modern humans were not interbreeding in the Levant.
Likewise the skull of what was originally thought to be a cross-species child later turned out to be just another Neanderthal (DNA studies).
Then you have Paabo's claim that Europeans and Asians have 1 - 4% Neanderthal genes but that Africans do not. There are two problems with that, either one fatal.
Problem one involves the recent human bottleneck; as Vendramini and other sources note, the human population of the planet appears to have been cut down to fewer than 100 individuals some time around 40K - 45K years ago by standard dating. Any crossbreeding with a glorified ape PRIOR to the bottleneck and Africans would have the good glorified-ape genes. Any crossing AFTER the bottleneck and not involving Africans as claimed, and the genetic gap between Africans and everybody else would be gigantic, rather than minuscule as it actually is. Now, the cross-species breeding would have to have been either before or after the bottleneck and impossible consequences are implied by either case.
Problem two amounts to the problem of thinking that a Neanderthal male could/would rape a woman and, rather than cooking and eating her afterwards as usual, somehow or other keep her alive long enough to bear a cross-species child, raise that child to reproductive age, and have him/her breed back into human populations without anybody catching on.....
In real life:
- Neanderthal females would kill that woman the first time her new owner left her alone for ten minutes.
- The woman wouldn't fare any better than the subjects of the commie attempts to breed humans and apes into super workers in the 1930s (no subjects survived).
- Humans would notice the child was different (the fur coat, the odd taste for bananas etc.).
- Humans would kill that child and everybody else like him as part of the same program which killed out the Neanderthal. They would not need DNA tests to determine who to kill for that sort of reason, it would be exceedingly obvious.
Cro Magnons hated Neanderthals and presumably also all other hominids from day one. They apparently lived close to Levantine Neanderthals for some time prior to wiping them out and then prosecuted a war of extermination against European Neanderthals so that the Neanderthal in Europe perished in a wave from East to West as they came into contact with Cro Magnons. There is no way that these same Cro Magnons would ever have allowed any human/hominid cross-breeds to survive.
The basic, cold, hard reality is that no living human has any Neanderthal or other hominid blood in him/her whatsoever, or is descended from Neanderthals or any hominid in any way whatsoever. Paabo and at least a few of his associates are in need of some sort of a course in basic logic.
