I got this comment on Youtube.
I had to click on his username, only to find out that his last upload is a 'documentary' about an alien city in Antarctica. 🤦

Fresh article in PNAS, by Udara Amarathunga & co.
Using geochemical data and numerical models, we identify oxygenation of the Mediterranean and a 33kyr salinity stratification in the earliest Pliocene, both consistent with the Zanclean Megaflood hypothesis

How many citations would you grant these two scientists whose names form today the words ‘Medicine’ and ‘Algorithm’?
Both grew in this madrassa in the 8 and 9th c. in the underrated millenary civilisation of Khorezm, a persian-arab region in today’s Uzbekistan.

Interesting, physicists☝️ embrace extraterrestrial life more than astrobiologists🤔
What I find weird about the latter is their believe that it's full of life out there but magically it never becomes as "sophisticated" as ours.

This 2021 paper seems to solve the old mystery about the origins of basque culture using genome.
In common with Iberia: more Paleolithic ancestry and less mix with Yamnayas. Differentiation came from less mix romans&arabs, feeding back with language isolation

This salt in Bogotá, Colombia, formed in the Cretaceous at the rift between today’s Mexico and Colombia about 150 million years ago, and raised to 2500 m above sea level during the late Tertiary period, when the Andes were formed.

In just one week we have learnt that H.erectus made bone tools in Olduvai (Tanzania) at about the same time that H.aff.erectus in Atapuerca (Burgos, Spain), 1.1 to 1.5 My ago.
