Human Civilization Older Than Expected, Early Population Explosion 80,000 Years Ago

% of readers think this story is Fact. Add your two cents.



 

 
About 10,000 years ago, the Neolithic age ushered in one of the most dramatic periods of human cultural and technological transition, where independently, different world populations developed the domestication of plants and animals. The hunter-gatherers gave rise to herders and farmers. Changes to a more sedentary lifestyle and larger settlements are widely thought to have contributed to a worldwide human population explosion, from an estimated 4-6 million people to 60-70 million by 4,000 B.C.

Now, researchers Aimé, et al., have challenged this assumption using a large set of populations from diverse geographical regions (20 different genomic regions and mitochondrial DNA of individuals from 66 African and Eurasian populations), and compared their genetic results with archaeological findings. The dispersal and expansion of Neolithic culture from the Middle East has recently been associated with the distribution of human genetic markers.

They conclude that the first significant expansion of human populations appears to be much older than the emergence of farming and herding, dating back to the Paleolithic (60,000-80,000 years ago) rather than Neolithic age. Therefore, hunter-gatherer populations were able to thrive with cultural and social advances that allowed for the expansion. The authors also speculate that this Paleolithic human population expansion may be linked to the emergence of newer, more advanced hunting technologies or a rapid environmental change to dryer climates.

Finally, they also suggest that strong Paleolithic expansions may have favored the emergence of sedentary farming in some populations during the Neolithic. Indeed, the authors also demonstrate that the populations who adopted a sedentary farming lifestyle during the Neolithic had previously experienced the strongest Paleolithic expansions. 

 
Conversely, contemporary nomadic herder populations in Eurasia experienced moderate Paleolithic expansions, and no expansions were detected for nomadic hunter-gatherers in Africa. “Human populations could have started to increase in Paleolithic times, and strong Paleolithic expansions in some populations may have ultimately favored their shift toward agriculture during the Neolithic,” said Aimé.

      There is no evidence proving the species Homo sapiens has been on earth for more than 6,000 years.

      Mr. Parrish — albeit an interesting writer — has a tendency to preach the secular science point of view which does not hold water.

      Shunning and denying that there is something beyond will not make it go away.

        I disagree. There is abundant evidence humans have been around much longer than that. However, if a person has been brainwashed to believe human civilization has only been around that long no amount of evidence will ever convince them otherwise. It will be considered falsified, or perhaps ‘secular.’ This idea of 6,000 years is only prevalent in western cultures. Ask any Hindu an they’ll tell you that their tales of witnessing the ‘gods’ fly around in arial craft and shooting advanced weapons at each other date back at least 80,000 years.

        The reason recorded history only goes back a few thousand years is that all civilization and all records of it were erased in a worldwide flood at some point anywhere from 8,000 to 13,000 years ago. The very few people who survived were reduced to hunting and gathering and furthermore chose to renounce technology as they saw it as the cause for their great tribulation. This technology has been reintroduced to us over the past 200 years and we are rapidly following in the footsteps of our ancestors.

        These ‘gods’ spoken of in our various mythologies are actual other-worldly beings, but not necessarily from other planets- but from other planes of existence. Some of them wish to help us grow and evolve spiritually (you might call them angels) while others wish to control us and even be worshipped by us (you might call them demons). The truth about our history has been suppressed by said demons through fear and intimidation for so long that most people are afraid to even consider the possibility of other explanations of our existence beyond what the various religions have been selling us. But the time of their influence is coming to an end. We are waking up and they are pulling out every trick in the book to distract and confuse us.

        There will be an answer. Let it be.

          China has recorded history dating back over 4000 years. As in, they were cultured and organized enough to start keeping records. And within those records they talk about much earlier times.

          OP is a brainwashed idiot, or a troll. If he’s brainwashed, I bet he doesn’t believe in Dinosaurs either.

      Lower Palaeolithic flint handaxes, cleavers, and scrapers dating from at least 130,000 BCE at nine sites near the town of Plakias on Crete shows that early humans travelled out of Africa by sea much earlier than had previously been estimated. Some of these stone tools could be significantly older than circa 130,000 BCE since they resemble hand axes fashioned in Africa circa 800,000 BCE by early hominins.
