Ancient Eurasians frequently migrated and interacted w/each other 35kya. Denisovan DNA fragments in the ancient genome overlap with today’s East Asians yet are different from modern people in Oceania. Modern humans and Denisovans likely to have mixed multiple times @ExogenesisHH

• 16 new ancient genomes from the southern Tibetan Plateau (4400–3500 BP). • Continuity and divergence of local plateau ancestry over a millennium. • Detected Basal Asian ancestry signals from southwestern China. • Revealed sex-specific patterns and EPAS1 shifts

“This group mixed with early Neandertals and was then replaced by Denisovans who had mixed with later Neandertals.” Mixing all the way down. biorxiv.org/content/10.110…

#FossilFriday at Sima de la Huesos (Spain) more than 7,500 fossils, including 17 skulls, from 29 individuals have been recovered, representing all parts of the skeleton. The oldest remains are dated to as far back as 430,000 years. Nearby sites have produced even older fossils.

Global trade routes shipping copper (and who knows what other things) likely existed thousands of years ago. Perhaps spanning further into the ice age.

Most people don't know this but around 800,000 years ago an event called the Paternal Haplogroup Bottleneck occurred; a massive, highly selective genetic culling from 13 genetically similar male lineages down to ONE specific haplogroup. Suddenly and inexplicably (stay with me...)

"First we have all these genetic changes that don’t appear to be random at all, as you would expect when looking at the world from a Darwinian perspective. They seem to be highly directed. All these changes would also have taken place in the same period about 800,000 years ago."

If they had left part of the enclosure filled until today, our modern technologies would have almost certainly found a range of evidence types for better dating construction, possibly even identifying artefacts in various layers. Full clearing destroyed valuable data.

BREAKING: Sugars essential for life have been found in pristine asteroid Bennu samples collected by NASA’s OSIRIS-REx spacecraft. Combined with previous detections of amino acids and nucleobases, we see that life’s ingredients were widespread throughout the solar system:

Wow! “French marine archaeologists have discovered a massive undersea wall off the coast of Brittany, dating from around 5,000 BC”. bbc.co.uk/news/articles/…

Roko 🐉 Denisovan ancestry among present-day East Asians is at roughly 0,09–0,13%. It peaks among Papuans and Aeta at 2–5%. Europeans have it at 0,01–0,02% via geneflow from Asia.

It is with profound sadness and a heavy heart that we announce yesterday's passing of Erich von Däniken on January 10, 2026. Our thoughts are with his family. EvD is also mourned by his friends around the world, the millions of readers of his books, and the many colleagues who

Michael Button I appreciate your work, but this is a false premise. The fastest period of brain size expansion and reconfiguration occurs between 800,000 to 200,000 years ago, with a long list of underlying genomic changes. Your question is largely answered once you explore these factors.

🚨Exciting news for archaeology and for human knowledge in general! It has been a long and tedious process, but the Peruvian Ministry of Culture has finally granted permission to export geological samples that will hopefully enable the age of Sacsayhuaman's construction to be
