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.

Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’
Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’
DNA
For several decades, paleontologists have described Miracinonyx trumani -- an extinct species of cheetah-like felid that roamed the North American prairies and steppe terrains more than 13,000 years ago -- as North America’s answer to the African cheetah (Acinonyx jubatus). The post Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’ appeared first on Sci.News: Breaking Science News.

The secret hidden in these ancient manuscripts isn’t written in ink
DNA genetics
Researchers can now recover DNA from centuries-old parchment without damaging the manuscripts, turning historic documents into unexpected genetic time capsules. The hidden clues could reveal ancient trade routes, livestock history, manuscript origins, and details of everyday life stretching back more than a thousand years.

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.
