According to population genetics and anthropology, our homo sapiens subspecies sapiens (anatomically modern humans H.s.s) has grown to the alleged population of 7.5 billion from a group of 20-30 persons that appeared in Africa 120-150 000 years ago and moved back and forth through Sinai to Eurasia.
The population counter of UN Institute of the population is badly out of order as it takes into account manipulated numbers supplied by China, India and Pakistan. China claims 1,4, India 1.4 billion of citizens. Both numbers are fictional and made to order of ruling powers, and badly marry with facts.
The population of 20 major cities in China is 250 million, 50% of the population live in cities, grain production 500 mln tons, rice 200 mln tons. Average per head consumption including transformation is 1 ton per annum. Population estimate does not exceed 700 million.
The population of 20 major cities in India is 75 million, 15% of the population live in cities, grain production 300 mln tons, rice 200 mln tons. Average per head consumption including transformation is 1 ton per annum. Population estimate does not exceed 500 million.
Corollary: the actual population is closer to 5 than to 8 billion people.
H.s. sapiens subspecies has barely survived the Ice Age that started 110 000 years ago and finished 10 000 years ago but was followed by “stimulating” Little Ice Ages and volcanic eruptions.
Europe had good luck with the early medieval warm period of from 850 to 1350 followed by Little Ice Age of 1350 to 1850 that literally pushed it into Renaissance and Enlightenment, induced scientific and technical superiority compared to Eurasia.
Present Chart of climate waves is based on ice core probes from Greenland is irrefutable, historical legends referred thereto are not. Being based on erroneous chronology all events, empires, kingdoms prior to XVIth century “related” in consensual history are alleged.
The Northern hemisphere became suitable for the agriculture ensuring our species fairly stable survival conditions. We restarted multiplying. Anthropology, DNA genetics, population genomics, modern evolutionary synthesis allow tracking the movements of subspecies population across the globe.
According to UN Population Institute, world population reached 1 billion by 1800 AD. UN Institute considers that humans can form a self-sustainable civilization with an initial population of 73 000.
Input: species X multiply in couples, produce 3 surviving children, have 25 years lifespan, favorable survival conditions are present, i.e. ideal fluvial agriculture in the delta of Nile, survival territory Y (Egypt, Mare Nostrum coasts).
Output: exponential population growth of 18% per generation of 25 years or annual 0.72% growth, and our species reaches after 48 generations the population of 1 billion in 1800 AD from starting initial population of 73 000 in 600 AD, die-outs due to the development of large sea and land transportation networks are excluded.
The above reverse calculation of the population growth points to the low probability of the complicated world history lasting over 1500 years to have really taken place as related. There was simply not enough population for all the events, characters, wars, armies of hundreds of thousands of warriors battling all over Eurasia.
On the contrary, it is highly probable that the artifacts and events related by the consensual version of history as very ancient have actually taken place in Xth-XVIth centuries. Most of these events and artifacts may have interpretations very different from the ones of the consensual history.
Compact history hypothesis: by approx. 1000 AD the population of our species reaches 2 million, forms a polytheistic proto-state Kem in Egypt, invents statehood, religion, literacy, basic instruments, armaments, and warfare, morphs into monotheistic Judea-Israel Empire and spreads in Europe. By approx. 1200 AD Judea-Israel Empire starts to expand as an Orthodox Catholic Christendom Empire in Europe and Eurasia.
The Medieval Warm Period of 850–1350 A.D. in Northern Europe A.D. helped the growth of agriculture, construction, trade, and industry. The economic consequences of the Little Ice Age of 1350 – 1850 lead to the peasant revolts, Jewish pogroms, the sack of rich Catholic monasteries, facilitated the Protestantism, social and industrial revolutions.
By approx. 1400 AD Christendom Empire transforms into the centralized “Evil Empire” of Eurasia that disintegrates by approx. 1600 AD. The over-abundant inconsistencies of the consensual history show that it is not a Science, but an Art of inventing the fairy tales of ‘ancient’ Egypt, Greece, Rome, Persia, India and China that served the separation of Europe from Eurasia on the agenda of the ruling powers of the Western Europe of XVI-XVIIth centuries.
