Part 5: Evolution of Oriental & Neanderthal Humans
ca. 100,000 to 50,000 y.a.
- The study uncovered the first solid genetic evidence that "modern" humans ... interbred with their Neanderthal neighbors....
- most humans have a little Neanderthal in them—at least 1 to 4 percent of a person's genetic makeup.
- The results showed that Neanderthal DNA is 99.7 percent identical to modern human DNA, versus, for example, 98.8 percent for modern humans and chimps
- Chinese and Melanesians are as closely related to Neanderthals" as Europeans
- Trinkhaus [said] most living humans probably have much more Neanderthal DNA than the new study suggests. "One to 4 percent is truly a minimum"
"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..."
"He said his team ran four separate tests for authenticity - checking whether other amino acids had survived, making sure the DNA sequences they found did not exist in modern humans, making sure the DNA could be replicated in their own lab and then getting other labs to duplicate their results. Comparisons with the DNA of modern humans and of apes showed the Neanderthal was about halfway between a modern human and a chimpanzee."
Mueller-Karpe, the first name in continental paleoanthropology, wrote thirty years ago on the two strata of homo erectus at Swanscombe/England: "A difference between the tools in the upper and in the lower stratum is not recognizable. (From a geological point of view it is uncertain if between the two strata there passed decades, centuries or millennia.)" (Handbuch der Vorgeschichte, Vol I, Munich 1966, p. 293).
The outstanding scholar never returned to this hint that in reality there may have passed ten years where the textbooks enlist one thousand years. Yet, I tried to follow this thread. I went to the stratigraphies of the Old Stone Age which usually look as follows
modern man (homo sapiens sapiens)
Neanderthal man (homo sapiens neanderthalensis)
Homo erectus (invents fire and is considered the first intelligent man).
In my book "Wie alt ist das Menschengeschlecht?" [How Ancient is Man?], 1996, 2nd edition, I focused for Neanderthal man on his best preserved stratigraphy: Combe Grenal in France. Within 4 m of debris it exhibited 55 strata dated conventionally between -90,000 and -30,000. Roughly one millennium was thus assigned to some 7 cm of debris per stratum. Close scrutiny had revealed that most strata were only used in the summer. Thus, ca. one thousand summers were assigned to each stratum. If, however, the site lay idle in winter and spring one would have expected substratification. Ideally, one would look for one thousand substrata for the one thousand summers. Yet, not even two substrata were discovered in any of the strata. They themselves were the substrata in the 4 m stratigraphy. They, thus, were not good for 60,000 but only for 55 years.
I tested this assumption with the tool count. According to the Binfords' research--done on North American Indians--each tribal adult has at least five tool kits with some eight tools in each of them. At every time 800 tools existed in a band of 20 adults. Assuming that each tool lasted an entire generation (15 female years), Combe Grenals 4,000 generations in 60,000 years should have produced some 3.2 million tools. By going closer to the actual life time of flint tools tens of millions of tools would have to be expected for Combe Grenal. Ony 19,000 (nineteen thousand) remains of tools, however, were found by the excavators.
There seems to be no way out but to cut down the age of Neanderthal man at Combe Grenal from some 60,000 to some 60 years.
I applied the stratigraphical approach to the best caves in Europe for the entire time from Erectus to the Iron Age and reached at the following tentative chronology for intelligent man:
-600 onwards Iron Age
-900 onwards Bronze Age
-1400 beginning of modern man (homo sapiens sapiens)
-1500 beginning of Neanderthal man
between -2000 and -1600 beginning of Erectus.
Since Erectus only left the two poor strata like at Swanscombe or El-Castillo/Spain, he should actually not have lasted longer than Neanderthal-may be one average life expectancy. I will now not go into the mechanism of mutation. All I want to remind you of is the undisputed sequence of interstratification and monostratification in the master stratigraphies. This allows for one solution only: Parents of the former developmental stage of man lived together with their own offspring in the same cave stratum until they died out. They were not massacred as textbooks have it:
monostrat.: only modern man's tools
interstrat.: Neanderthal man's and modern man's tools side by side
monostrat.: only Neanderthal man's tools
interstrat.: Neanderthal man's and Erectus' tools side by side
monotstrat.: only Erectus tools (deepest stratum for intelligent man)
The year figures certainly sound bewildering. Yet, so far nobody came up with any stratigraphy justifiably demanding more time than I tentatively assigned to the age of intelligent man. I always remind my critiques that one millennium is an enormous time span--more than from William the Conqueror to today's Anglo-World. To add a millenium to human history should always go together with sufficient material remains to show for it. I will not even mention the easiness with which scholars add a million years to the history of man until they made Lucy 4 million years old. The time-span-madness is the last residue of Darwinism.

* I'd like to include dinosaurs and the large mammals on the list. I'd guess that the dinosaurs ended around 10,000 y.a. and the giant mammals ended 4,500 years ago. Those were both times of cataclysms.
* I suppose the dinosaurs began at least a few 100,000 y.a. and mostly died out before the first humans, but some stragglers survived until 10,000 y.a..

At about 74,000 years ago, Mount Toba on the island of Sumatra erupted in a massive explosion that supposedly rocked the Middle Palaeolithic world to its very foundations, bringing contemporary human populations to their knees, reducing the global population level to around 15,000 individuals, thereby precipitating a so-called bottle-neck of human evolution, as proposed by Stanley Ambrose, from the University of Illinois at Urbana-Champaign, discussed in this BBC News article from 1998, and in an essay at the Bradshaw Foundation, in the same year. However, recent discoveries made by Michael Petraglia, from the University of Cambridge, have now cast doubt on this theory…
(the team)…found the stone tools at a site called Jwalapuram, in Andhra Pradesh, southern India, above and below a thick layer of ash from the eruption of the Toba volcano in Indonesia — an event known as the Youngest Toba Tuff eruption.
The tools from each layer were remarkably similar, and Petraglia says that this shows that the huge dust clouds from the eruption didn’t wipe out the population of tool-using people. “Whoever was there seems to have persisted through the eruption,” he says.
This is the first archaeological evidence associated with the Toba super eruption, says Petraglia, and it contradicts theories that the eruption had a catastrophic effect on the area that its ash blanketed.
Following this eruption, a phase of dramatic global cooling ensued, evidenced by a 6-year global winter, which in turn was followed by the onset of the Würm glaciation event. Petraglia proposes that only modern humans could have survived such an event, giving as his evidence the supposed similarity of the lithic assemblage, and purported others, which he claims correspond with those found in Africa dating to around 100,000 bp, by which time modern anatomically modern humans had been extant there for some 100,000 years.
Petraglia thinks that modern humans — rather than Neanderthals or other hominins — are the only species that would have been able to persist through an event as dramatic as the Toba eruption. This theory will spur much debate, he admits, because modern humans were not thought to have reached India, from Africa, so long ago. “It’s controversial,” says Petraglia, “but it makes a lot of sense.”
Petraglia and his team compared the tools they found to others from Africa from different periods in this week’s edition of Science1. The Indian tools look a lot like those from the African Middle Stone Age about 100,000 years ago, when modern humans were thought to have lived, he says. “Whoever was living in India was doing things identical to modern humans living in Africa.” Neanderthal toolkits found in Europe are very different, he says. This is more evidence, he says, that the plucky ash-covered inhabitants of Jwalapuram were modern humans.
However, we know that modern humans weren’t the only individuals capable of withstanding sudden and extreme climate change, as Eurasian Neanderthals lived through the Riss glaciation which occurred from 180,000 bp – 130,000 bp, and they also survived the Mount Toba event, regardless of its supposed global impact. It’s possible too that Homo erectus lived on as late as 50,000 bp in Asia, and if Homo floresiensis turns out to be a genuine new species, they too survived this event (n.b. – but see this latest update from John Hawks, which I’ll attempt to address later)
Moreover, lithic assemblages, whether in India, Africa or Europe don’t always indicate exactly which species of Homo may or may not have been responsible for their manufacture, as pointed out by Stanley Ambrose…
(who) disagrees with Petraglia’s conclusions. “It is highly speculative to say the eruption had no impact,” he says. Ambrose argues that Petraglia’s sample size is too small to make proper comparisons with other tools. And, he adds, “stone artifacts cannot be used to differentiate Neanderthals from African moderns.”
…which raises the question of exactly which species of Homo would have been living in India at the time of the Toba event. At 74,000 years bp, it is generally assumed that anatomically modern humans were still resident only in Africa, from where they would emerge at around 50,000 bp to commence their purported total replacement of all other species across the globe, culminating in the extinction of the Neanderthals at around 24,500 bp.
However, we know this can’t be true, because as John Hawks points out in his post on this topic, Australia was populated by moderns by at least 50,000 bp, and quite possibly even earlier still, at around 60,000 bp, depending on one’s interpretation of the widely different/wildly conflicting dates given for Mungo Man. And if Homo erectus managed to navigate the open seas to Flores at 840,000 bp, it would appear that modern human behaviour is a great deal more ancient than in its comparatively youthful Middle and Upper Palaeolithic claimed origin, meaning that theoretically any species of human from Homo erectus up to and including early Homo sapiens could have prevailed in a post-Toba environment.
