When they started colonizing Tasmania, at the beginning of the 19th century, the British came to the conclusion that the inhabitants of that island were the least developed human community on Earth. The Tasmanian aborigines were incapable of mastering fire, they did not manufacture bone tools, they did not possess specialized stone tools, they did not use composite tools (e.g. axes with handles), they did not have boomerangs, spear launchers, shields, nor did they chop trees or engage in mural painting. Although they were living especially in coastal regions, the Tasmanians were incapable of fishing. Although they were living in a region with rather cold winters, they were not capable of sowing their own clothes – they could only cover their bodies with animal skins. Although they were members of the Homo Sapiens species, the material part of their civilization was inferior to the one achieved by the Homo Neanderthalensis and perhaps even by Homo Erectus (a species which most likely had already managed to master fire).


However, the British were not mistaken. The Tasmanian population was not the most evolved but the most degenerated in the entire world. The Tasmanian once had a superior material civilization, which included all of the achievements mentioned above, but which they lost in only a few thousand years.


The aborigines arrived in Tasmania at least 35,000-40,000 years ago, following a migration from Africa, along the Southern coast of Asia. At the time Tasmania was connected to Australia and only after the end of the last Ice Age did it become an island, as a consequence of a large part of the icecap melting and a rise in the water level. At the beginning of British colonization, the Tasmanian had been isolated from the rest of the world for more than 10,000 years. This was a period when they evolved on their own, without outside influence. The Tasmanian never actually suffered any British influence, as they were quickly exterminated.


Nobody provides a satisfying explanation for the degeneration of the Tasmanian civilization and that is because everything within human-related sciences is altered by various ideological filters.

’Scientists’ of political correctness (a new Inquisition of science) normally argue that the Tasmanian were too few to support civilization – even a Paleolithic-type one. It is estimated that the Tasmanian population amounted to 3,000-15,000 members. However, the Neanderthal population was of the same size, whose civilization not only did not degenerate over hundreds of thousands of years, but also continually evolved. In addition, contacts between human Neanderthal groups were not as frequent, as the area they covered was much larger than the one covered by Tasmanians. Hence, the small size of the population cannot be a serious argument for losing a certain level of civilization unless coupled with the distribution of intelligence according to the Gaussian curve. For a certain average IQ, it is necessary for a population to have a certain size in order to possess sufficient members with a sufficiently high level of intelligence in order to preserve the achievements of that civilization. For an average IQ of 60 (this was the measured IQ for Australian aborigines), the Tasmanians were too few to preserve their civilization. With an IQ which was probably much higher, the Neanderthals, although with a population not larger than the Tasmanian, had enough members to continually perfect their civilization. Nonetheless, the ’scientists’ of political correctness prefer to ignore the only plausible explanation for the degeneration of Tasmanian civilization and of any other civilization: the decrease of the IQ as a consequence of a decrease in the pressure of selection.


Racist scientists will not be particularly fond of this thesis either. If they accepted the genetic degradation of intelligence for the Tasmanian, they would then be forced to accept the same for other races which they see as being forever superior – something which would blow away the very foundations of their ideology.


Nature however does not take ideological whims into account. The decline of human intelligence has been ongoing for tens of thousands of years everywhere around the world. The cause is always the same: a lower level of natural selection.


As all other humans, except for the ones in Sub-Saharan Africa, the Tasmanians were not pure Homo Sapiens but hybrids. In their genome, around 4% were Neanderthal genes and equally around 4% were the genes of the Denisova hominin– the same proportions as for Melanesians and Australians  This is already proof of the fact that at the peak of the Ice Age Tasmanian ancestors had reached sufficiently Northern latitudes to require a high level of intelligence.


The genetic degeneration of Tasmanian intelligence did not begin only once they were isolated on the island, but long before that. On the one hand, moving towards the South and living in the equatorial and tropical climate decreased the pressure of selection: humans required fewer calories in an environment which could provide more. On the other hand, hunting was (and especially so in Australia) much easier than in Asia while predators, human’s natural competition, were also more rudimentary and less intelligent. Moreover, as the region was not inhabited by other humans until this first migration, there was no human competition either. It is obvious that the humans who migrated to Tasmania were subject to a much lower pressure of selection than the humans who migrated towards Northern Eurasia. The fact is reflected by the current difference in IQ levels: the British Australian population has an IQ of 100 while the aborigines have an IQ of 60.


A similar phenomenon, although not of the same amplitude and duration, explains the IQ decrease for American natives. They originate in a Siberian population, of which probably only a few tens of thousands of members penetrated into America, about 11,000 years ago. They did so over the Behring Strait which at the time was no covered by waters but was a strip of land covered by ice. These humans were so intelligent and efficient that in approximately 1,000 years they managed to colonize the entire continent and exterminate 80% of the North American megafauna and 85% of the South American one. In the same millennium they managed to reach a population of millions of people. The price to be paid for this spectacular expansion was a decrease of the IQ (but not as dramatic as the one in Tasmania and Australia). Having a more numerous population with a higher IQ (today it stands at 87), the American natives not only did not lose the achievements of the civilization which they brought with them on the new continent; along with the end of the Ice Age, they managed to build much more complex civilizations, similar to the Eurasians: they invented agriculture, domesticated animals, processed metals, developed urban agglomerations and even empires, they gained scientific knowledge, etc. This additional development of civilization led to an additional decrease of the IQ. Following contact with European colonists, the IQ dropped even further – first through the decimation of American native elites and then by way of an accelerated reduction in the pressure of selection due to the Industrial Revolution.


Returning to the loss of Tasmanian civilization, the phenomenon which occurred on the little island illustrates the direction that the entire world is heading towards. The fall of civilizations consists of a loss of certain achievements (material or cultural). The Egyptians were no longer capable of building pyramids. The Greeks invented democracy but lost it. The world after the fall of the Roman Empire was no longer capable for a very long time of creating buildings that were similar to those of Roman engineers. In addition, as regards philosophy, science and art, the medieval world did not manage for very long to catch up with the ancient one. At all times and places, the fall of civilizations was due to the loss of IQ. The recovery of lost achievements always occurred only as a result of significant technological progress. Technological progress worked as prosthesis to replace the increasingly weaker minds of the ever larger share of the population. For instance, the general decline of IQ in the world leads to the consequence that fewer and fewer people are capable of solving simple arithmetic operations. But the invention of the calculator and its widespread use has enabled these people to reach correct results.


The genetic degradation of intelligence is, however, an inevitable phenomenon which is irreversible, global, whose beginnings can be found during the Upper Paleolithic and which will once day lead us all to the same situation as that of Tasmanians.
