Stories of mystery or lost civilisations have captivated our imaginations for centuries – from Atlantis and Shambhala in the Old World, to the search for El Dorado in the Americas. Hard proof for the existence of such lost civilisations seems thin, and their existence is in general dismissed by the academic community. However, is it plausible to suggest, more generally, that civilisations may have risen and fallen before the beginning of the historical record? The finding that Neanderthals interbred with progressed humans, published in 2010, will have to mean that we are the same species. In fact, the capacity of two organisms to breed and fabricate fertile offspring is the definition of a species. This pushes back the speciation of Homo sapiens to someplace around 600,000 years ago. We have been walking the Earth for over half a million years, and yet our historical noesis goes back just 6,000 years at most. The prehistory of our species encompasses 99% of our past. The hypothetical existence of long lost civilisations lurking within that time frame is a tantalising possibility, and worthy of investigation. The Rise of Civilisations The last ice age ended around 12,000 years ago. Almost without delay after this, agriculture begun to simultaneously develop in assorted locatings around the globe. This led to more settled populations, which, in turn, led to the introductory cities and the emergence of civilisation. In the Old World, civilisation produced in the Middle East (Mesopotamia), Ancient China and the Indian Subcontinent (the Indus Valley Civilisation). All of the subsequent Eurasian and north African civilisations may arguably trace their inheritance back to these three ancestral cultures. In the New World, civilisations arose in Mesoamerica (the Olmecs, Mayans, Aztecs, etc.) and South America (Norte Chico, the Incas, etc.). The great signification of these cultures is that they arose wholly independently from all similar developments in Eurasia. This implies that civilisation was not just a fluke – persons will likely invent civilisation wherever conditions grant them to do so. Given that within the 1% of humane history that we are conscious of, civilisation has developed in five distinguished locations, why will have to we not assume that there have been hundreds of lost civilisations in the prehistoric past? Lost Civilisations – Possible Objections One limiting factor is the Earth’s cycle of ice ages. Within an ice age, there are glacial and interglacial periods. Agriculture is known to have only invented with the beginning of the current interglacial period, 12,000 years ago. However, within our 600,000 year time frame, there have been a number of other interglacial periods: the Günz-Mindel interglacial (620 to 455 kya), the Mindel-Riss interglacial (380 to 200 kya) and the Riss-Würm interglacial (130 to 110 kya). Given that agricultural development started out as soon as the current interglacial amount of time began, it seems plausible to suggest that similar bursts of agricultural development occurred with the beginnings of these prior three phases. In fact, the interfering glacial periods seem like a good comprehensible statement as to why no records of any prehistoric civilisations would have pulled through to the present day. Another point to take into thoughtfulness worries humane migration patterns. Modern people are only thought to have left Africa around 60,000 years ago. However, the ancestors of the Neanderthals are thought to have left Africa around 600,000 years ago. If we are the same species, then this dates the initial Homo sapien exodus from Africa to the beginning of our prehistoric time frame. Archaeology Another objection comes from archaeology. Behavioural modernity is many times affiliated with a leap in technical innovation which occurred around 50,000 years ago. This marks the boundary among the Middle Stone Age and the Later Stone Age. In the Middle Stone Age, tools were simplistic, and had scarcely changed for hundreds of thousands of years. However, from 50 kya onwards, there was a rapid increase in the diversity and complexity of the humane tool kit. This would suggest that, prior to this time, persons lacked the accomplishments necessary to construct agriculture and, subsequently, civilisation. However, this assumption is based on archaeological findings. Prior to the European invention of the Americas, a great deal of of the indigenous tribes who lived in the areas surrounding the Meso- and South American civilisations were using comparatively primitive stone age tool kits (although admittedly still significantly more innovative than Middle Stone Age implements). At the very least, this demonstrates that civilisations may construct in the midst of technologically primitive cultures. In addition, I suggest that there are reasons to suppose that little archaeological remains would subsist of any lost prehistoric civilisations even if they had developed more complex technology. Fallen Civilisations – What Would Remain? Bob Holmes, a writer for New Scientist magazine, has speculated as to what would take place to our innovative civilisation if all humane beings were abruptly wiped off the face of the planet by numerous mysterious, hypothetical disaster. Holmes states that innovative buildings are engineered to last around 60 years, while bridges and dams are respectively built to last 120 and 250 years. Although ruins may remains for hundreds of years, a good deal of structures would vanish to an outstanding degree quickly. In addition, Brad Stelfox, a land-use ecologist in Northern Canada, estimates that 80% of urban areas in that region would be enclosed by forest within 50 years without humane intervention. Atmospheric carbon dioxide levels would be scaled down to 15% of current levels within a thousand years, and return to pre-industrial levels within 20,000 years. After 50,000 years, most glass and plastics would have degraded. Following this, the only remains of our worldwide, post-industrial civilisation would be a burst of radio waves spreading outwards from Earth throughout the universe. All archaeological artefacts on the planet itself would long since have disappeared. Given this, it seems unreasonable that we will have to suppose to find any archaeological remains of any civilisation which may have existed prior to the beginning of the last glacial period, 110,000 years ago. Conclusions There is an crucial distinction amongst civilisation and industrial civilisation. Although civilisation itself is known to have arisen in multiple places (and arisen quickly, once conditions were right), industrialisation is only known to have occurred once. Equally, a good deal of claims of long lost civilisations are blatantly spurious. However, our historical noesis has been drasti changed by new determinations galore times in the past. The Indus Valley Civilisation was unknown of until the 1840s. The invention of the Antikythera mechanism in the early twentieth century revealed that people had been creating clockwork mechanisms around 1.5 thousand years earlier than antecedently thought. Göbekli Tepe, ran into in the 1990s, revealed that hunter-gatherer peoples had been fabricating big stone temple complexes before the advent of agriculture and civilisation itself. Given the time that the humane race has expended on the planet, how fixed our historical psychological result of perception learning and reasoning is, and how quickly we have invented agriculture and settled populations where able, it seems difficult to imagine that there have not been at least a handful of – and perchance innumerable – lost civilisations in our prehistoric past. |
