Q. Recently, researchers of which university have discovered that Neanderthals from 50,000 years ago were infected with three viruses still present in modern humans?
Answer: Federal University of São Paulo, Brazil
Notes: Researchers at Brazil's Federal University of Sao Paulo discovered that Neanderthals 50,000 years ago harbored three viruses still impacting modern humans. This finding surpasses the previous record by 20,000 years, held by a 31,000-year-old common-cold virus. Marcelo Briones suggests it's feasible to synthesize these ancient viruses. The discovery, from DNA analysis of Neanderthal skeletons in Russia's Altai mountains, confirms ancient viral origins, ruling out contamination.
