Footprint in Patagonia

13 May 2019

At ... a human footprint that seems to shatter the peopling of the Americas mainstream song sheet. A sedimentary structure at Osome in southern Chile which is strongly associated with megafauna bones, as well as unifacial lithic tools, has what is said to be a Late Pleistocene footprint by a member of the Homo sapiens family. It is intimated that it is an hominid rather than a modern human footprint. Were the people in question related to the Denisovans or was it earlier, in the time of Homo erectus. Whatever, this is firm evidence of humans living in the Americans much earlier than the current consensus allows.

At ... abrupt climate change drove early South American population decline. Abrupt climate change sounds very much like a catastrophic event - and the date, at 8000 years ago, ties up with growing global evidence of an earth wide event in 6200BC. The study is published in Scientific Reports (May 2019) and is the first to demostrate how widespread in the Americas the decline of population was, and how rapidly the population climbed back up again. Inhabited sites at various localities in South America were suddenly abandoned. After 6000BC the population gradually recovered, coinciding with tropical plant management and early evidence of crop cultivation (between 6000 and 4200BC).

At ... the Tibetan Plateau was purportedly first occupied by humans as early as 40,000 years ago. A recent study by Chinese researchers on a human mandible find in NE Tibet has been published in the journal Nature (May 2019). It comes from an individual related to the Denisovans. Hence, by association we now know that these relatives of the Neanderthals also lived in East Asia.
