Olmecs had worked out the principle of the wheel, - Graham Hancock

Some Amazonian Native Americans descend partly from a Native American founding population that carried ancestry more closely related to indigenous Australians, New Guineans and Andaman Islanders than to any present-day Eurasians or Native Americans. This signature is not present to the same extent, or at all, in present-day Northern and Central Americans or in a 12,600-year-old Clovis-associated genome, suggesting a more diverse set of founding populations of the Americans than previously accepted.
[Quoting Pontus Skoglund]

If ever a society could be said to meet all the mythological criteria of the next lost civilization – a society that ticks all the boxes – is it not obvious that it is our own? Our pollution and neglect of the majestic garden of the earth, our rape of its resources, our abuse of the oceans and the rainforests, our fear, hatred and suspicion of one another multiplied by a hundred bitter regional and sectarian conflicts, our consistent track record of standing by and doing nothing while millions suffer, our ignorant, narrow-minded racism, our exclusivist religions, our forgetfulness that we are all brothers and sisters, our bellicose chauvinism, the dreadful cruelties that we indulge in, in the name of nation, or faith, or simple greed, our obsessive, competitive, ego-driven production and consumption of material goods and the growing conviction of many, fuelled by the triumphs of materialist science, that matter is all there is – that there is no such thing as spirit, that we are just accidents of chemistry and biology – all these things, and many more, in mythological terms at least, do not look good for us.

Human history has become too much a matter of dogma taught by 'professionals' in ivory towers as though it's all fact. Actually, much of human history is up for grabs. The further back you go, the more that the history that's taught in the schools and universities begins to look like some kind of faerie story.
