Un análisis genético de más de mil genomas británicos antiguos demuestra que la conquista romana dejó apenas una pequeña huella en la ascendencia de la isla a pesar de los importantes cambios culturales.

Investigadores del Instituto Francis Crick examinaron los genomas de 1039 individuos enterrados en Gran Bretaña desde la Edad del Bronce, en el 2550 a. C., hasta el 1150 d. C. El estudio reveló que la mayoría de las personas que vivieron bajo el dominio romano entre el 43 y el 410 d. C. trazaban toda su ascendencia hasta la Gran Bretaña de la Edad del Hierro, y solo un 20 por ciento mostraba una contribución genética externa detectable.

Ancient sheep DNA offers new clues to how a Bronze Age plague spread across Eurasia

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.

Ancient DNA uncovers origins of Britain's Bronze Age immigrants

Analysis of ancient DNA shows that people who replaced Britain's population around 2400 BC came from the river deltas of the Low Countries. These migrants, linked to the Bell Beaker culture, carried a unique mix of hunter-gatherer and early farmer ancestry preserved in wetland regions. Within a century, they accounted for 90 to 100 percent of Britain's genetic makeup, displacing the Neolithic farmers who built Stonehenge.

Ancient DNA reveals ethnic diversity among Goths

17 de marzo de 2026 Reportado por IA

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.

Study indicates male Neanderthals fathered most human-Neanderthal offspring

Genetic analysis suggests that interbreeding between Neanderthals and Homo sapiens involved mostly male Neanderthals and female modern humans. Researchers examined sex chromosomes to uncover this pattern, which occurred during multiple periods after humans left Africa. The findings point to mating preferences as the likely explanation, though experts call for more evidence.

Iron Age mass grave in Serbia suggests targeted killings

23 de febrero de 2026 Reportado por IA

Archaeologists have uncovered evidence of a brutal massacre at an Iron Age site in Serbia, where 77 individuals, mostly women and children, were violently killed over 2,800 years ago. The findings indicate an intentional act amid regional conflicts between pastoralists and settled farmers. The burial, accompanied by personal items and food remnants, points to a symbolic ritual.

Oldest cold virus identified in 18th-century woman's lungs

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.

Ancient fingerprint discovered on 2,400-year-old Danish war boat

16 de febrero de 2026 Reportado por IA

Researchers have uncovered a partial human fingerprint preserved in the caulking of the Hjortspring boat, Scandinavia's oldest plank vessel, suggesting its origins along the Baltic Sea coast. The 2,400-year-old boat, used in an Iron Age raid on Denmark's Als island, was analyzed using modern scientific methods. This finding provides new clues to a century-old mystery about the vessel's builders.
