Ancient DNA reveals Neanderthal group in Polish cave

Researchers have analyzed mitochondrial DNA from eight Neanderthal teeth found in Stajnia Cave in Poland, reconstructing the genetic profile of a small group that lived there around 100,000 years ago. The study, published in Current Biology, marks the first such multi-individual genetic picture from a single site north of the Carpathians. The findings show genetic links to Neanderthals across Europe and the Caucasus.

An international team extracted ancient mitochondrial DNA from eight Neanderthal teeth discovered in Stajnia Cave, located in southern Poland north of the Carpathians. The individuals lived during the same period around 100,000 years ago, allowing scientists to build a genetic profile of at least seven Neanderthals from one location and era. Andrea Picin, professor at the University of Bologna and study coordinator, described it as an extraordinary result. He noted that previous Neanderthal genetic data often came from single fossils or scattered remains, unlike this coherent picture from Stajnia Cave. Wioletta Nowaczewska of the University of Wrocław and Adam Nadachowski of the Polish Academy of Sciences called the achievement important for Polish research and European Neanderthal studies, exceeding expectations for the site. The mitochondrial DNA belongs to a genetic branch shared with Neanderthals from the Iberian Peninsula, southeastern France, and the northern Caucasus, indicating it was once widespread before being replaced. Mateja Hajdinjak of the Max Planck Institute for Evolutionary Anthropology highlighted that two juvenile teeth and one adult tooth share the same DNA, suggesting close relations. Sahra Talamo, also from the University of Bologna, urged caution with oldest chronologies, comparing it to the Thorin fossil from France dated around 50,000 years ago with similar genetics. The results underscore Central-Eastern Europe's central role in Neanderthal population movements and interactions during the Middle Paleolithic.

Researchers analyzing ancient DNA say they have detected the plague bacterium Yersinia pestis in the remains of a domesticated sheep from Arkaim, a Bronze Age settlement in the southern Ural region of present-day Russia. The team reports this is the first known identification of a Bronze Age plague lineage in a nonhuman host from that period, a finding that could help explain how an early, pre-flea-adapted form of plague traveled widely across Eurasia.

A new study indicates that Neanderthals and early Homo sapiens interbred over a broad area spanning most of Europe, the eastern Mediterranean, and western Asia. Researchers analyzed ancient genetic samples to map this hybrid zone, challenging earlier assumptions of a more localized interaction. The findings suggest repeated encounters as humans expanded from Africa.

Fossils unearthed in a Moroccan cave offer a precise glimpse into early human evolution, dated to about 773,000 years ago using Earth's magnetic field reversal as a timestamp. The remains, blending primitive and advanced traits, suggest an African population close to the shared ancestor of modern humans, Neanderthals, and Denisovans. This discovery highlights northwest Africa's key role in human origins.

A study of ancient DNA from graves in Bulgaria shows that the Goths were a multi-ethnic group with ancestries from Scandinavia, Turkey, North Africa and beyond. This finding challenges the traditional view of Goths as primarily Scandinavian migrants moving south. The research sequenced genomes from 38 individuals at two sites dating to the 4th century AD.

Archaeologists have identified the oldest genetically confirmed dog remains from a site in Turkey dating back 15,800 years, pushing the timeline for canine domestication by about 5,000 years. Additional remains from the UK, around 14,300 years old, show dogs were widespread across Europe during the hunter-gatherer era. The findings suggest early humans spread domesticated dogs through cultural exchanges.

Researchers have discovered genes that duplicated before the last universal common ancestor of all life, offering insights into evolution's earliest stages. These universal paralogs, present in nearly every organism, suggest protein production and membrane transport were among the first biological functions. The findings, published in Cell Genomics, highlight how ancient genetic patterns can reveal pre-LUCA history.

Scientists have identified the oldest confirmed human RNA virus in lung tissue from a woman who died in London around the 1770s. The rhinovirus, which causes the common cold, was reconstructed from fragmented genetic material preserved in alcohol. This discovery opens new possibilities for studying the evolution of RNA viruses in human history.
