Permineralized Jurassic fern rhizome from Korsaröd (Sweden) of Osmundastrum pulchellum. It has preserved Nuclei and Chromosomes, a fine subcellular detail has rarely been documented in fossils. It´s Rooted in DNA content was used to extrapolate relative genome, finding relationships with extant Osmundastrum cinnamomeum, and confirmed a monophyletic Osmunda. Osmundastrum pulchellum is one of the earliest fossil Osmundastrum rhizomes known so far, and the first of its kind from the Mesozoic of Europe. Its impressive preservation has lead to know even the biotic interactions with the Plant. It also has recovered the only know case know to preserve the ongoing mitosis processes in plant cells via calcification from volcanic hydrothermal brine.

DNA on the Shroud of Turin reveals centuries of hidden history
DNA discovery
DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel. The findings do not prove its age or authenticity, but they expose a hidden biological history preserved in the famous cloth.

Scientists found two mysterious ‘ghost’ ancestors hiding in our DNA
DNA genetics
Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans. Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups.

Ancient DNA reveals a chilling secret at China’s 4,000-year-old Shimao city
DNA China genetics
Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric contact.

Ancient DNA reveals the mysterious collapse of Europe's megalith builders
DNA migration genetics Homo sapiens human origin
DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.

The Neanderthal “love story” isn’t what the DNA actually shows
DNA migration reproduction evolution genetics Homo sapiens
Claims that Neanderthal men "preferred" Homo sapiens women may make for catchy headlines, but the underlying research does not actually show prehistoric romance. The genetic evidence only points to an uneven pattern of DNA inheritance, which could have been shaped by biology, migration, or social organization. Archaeological evidence suggests Neanderthal groups may have followed traditions where women moved between communities, opening the door to far more complicated explanations than simple at
