✍️ Researchers have sequenced the second high-quality genome of the Denisovans, an ancient human species that lived in Asia tens of thousands of years ago. The new genome reveals that the Denisovans had complex relationships with other ancient human species and modern humans.

👉 The Denisovans were an ancient human species that lived in Asia tens of thousands of years ago. 👉 The new genome sequence reveals that the Denisovans had complex relationships with other ancient human species and modern humans. 👉 The genome shows that the Denisovans had interbred with both Neanderthals and an unknown human species that lived in Asia. 👉 The study also found that the Denisovans had a unique genetic makeup that was different from both Neanderthals and modern humans.

✍️ Un equipo de científicos internacionales ha identificado un linaje genético propio del centro de Argentina con una antigüedad de 8500 años que todavía se encuentra presente en la población actual.

👉 Se identificó un linaje genético propio del centro de Argentina con una antigüedad de 8500 años 👉 El linaje genético se mezcló con otras poblaciones vecinas, pero sin que se produjeran reemplazos poblacionales 👉 La historia poblacional de Sudamérica se caracteriza por la permanencia prolongada de grupos humanos en los mismos territorios 👉 El estudio analiza el ADN de restos humanos procedentes de contextos arqueológicos del centro y norte argentino

EXPERTS: DOGE SCHEME DOOMED BECAUSE OF MUSK AND RAMASWAMY'S "MEME-LEVEL UNDERSTANDING" OF SPENDING

✍️ Billionaires Elon Musk and Vivek Ramaswamy, appointed by President-elect Donald Trump to lead the Department of Government Efficiency, propose cutting government spending by eliminating programs with lapsed spending authorizations, but experts argue this approach is misguided and may harm essential services.

👉 Musk and Ramaswamy propose cutting government spending by eliminating programs with lapsed spending authorizations 👉 Experts argue that this approach misunderstands the function and role of funding authorization in Congress 👉 The Constitution requires Congress to authorize all government spending 👉 The authorization that Musk and Ramaswamy take up actually refers to an internal House of Representative's rule 👉 Experts argue that the amount of wasteful government spending is far smaller than what Musk and Ramaswamy suggest

ANCIENT DNA REWRITES THE STORIES OF PEOPLE BURIED BY VOLCANIC ERUPTION IN POMPEII

https://media.zenfs.com/en/cnn_articles_875/7dd756fa499a7591358023b8aba86267

✍️ Ancient DNA analysis has revealed surprising information about the identities of people who perished in Pompeii after the volcanic eruption in AD 79, challenging previous misconceptions about their genetic relationships, ancestry, and sex.

👉 DNA analysis of Pompeii victims' remains reveals surprising information about their identities and relationships 👉 Previous assumptions about the relationships between bodies were incorrect 👉 Findings challenge traditional gender and familial assumptions 👉 Pompeii was a cosmopolitan city with a diverse population 👉 Research provides new understanding of population demographics in Pompeii during the Roman Empire

Pompeii DNA Overturns Long-Held Assumptions About Its Victims.

https://media.zenfs.com/en/sciencealert_160/0fad2f27094f9efcce26002a298cc7f8

The analysis, led by forensic archaeologist Elena Pilli, was conducted on fragmentary skeletal remains from 14 plaster casts, selected from 86 casts that are currently undergoing restoration. The findings challenge traditional gender and familial assumptions, revealing that an adult wearing a golden bracelet and holding a child was an unrelated adult male and child, and that a pair of individuals thought to be sisters or mother and daughter were found to include at least one genetic male. The study also reveals a greater genetic diversity in Pompeii than was suspected, with individuals studied being mainly descended from relatively recent immigrants from the eastern Mediterranean and Near East. ● Traditional assumptions about the identities and relationships of Pompeii victims were wrong ● An adult wearing a golden bracelet and holding a child was an unrelated adult male and child ● A pair of individuals thought to be sisters or mother and daughter were found to include at least one genetic male ● Pompeii had a greater genetic diversity than was suspected, with individuals being mainly descended from recent immigrants from the eastern Mediterranean and Near East
