Around this date, too, Homo sapiens neanderthalensis first appears, a quite distinct subspecies which most of us know as 'Neanderthal Man'. Tall, heavily muscled, with prominent brow ridges and a protruding face, Neanderthal Man had a bigger average brain size than modern humans (1400cc as against our 1360cc).7 The possession of such a big brain was no doubt an asset to these 'intelligent, spiritually sensitive, resourceful creatures'8 and the fossil record suggests that they were the dominant species on the planet from about 100,000 years ago until 40,000 years ago.

An Ojibwa tradition seems relevant. It speaks of a comet that 'burned up the earth' in the remote past and that is destined to return:
'The star with the long, wide tail is going to destroy the world some day when it comes low again. That's the comet called Long-Tailed Heavenly Climbing Star. It came down here once, thousands of years ago. Just like the sun. It had radiation and burning heat in its tail ...
Indian people were here before that happened, living on the earth. But things were wrong with nature on the earth, and a lot of people had abandoned the spiritual path. The Holy Spirit warned them a long time before the comet came. Medicine men told everyone to prepare. ... The comet burnt everything to the ground. There wasn't a thing left ...
There is a prophecy that the comet will destroy the earth again. But it's a restoration. The greatest blessing this island [Turtle Island/America] will ever have. People don't listen to their spiritual guidance today. There will be signs in the sun, moon and stars when the comet comes down again.

More than seventy different indigenous Amazonian cultures use ayahuasca — many giving different names to the brew (yajé, natema, caapi, cipo, shori, etc.).
