Princeton study maps 200,000 years of Human–Neanderthal interbreeding

Science Daily - Paleontology - Sun, 07/13/2025 - 03:01
For centuries, we’ve imagined Neanderthals as distant cousins — a separate species that vanished long ago. But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that Neanderthals never truly disappeared — they were absorbed. Their legacy lives on in our DNA, reshaping our understanding of what it means to be human.

Tiny fossil with razor teeth found by student — rewrites mammal history

Science Daily - Paleontology - Sat, 07/12/2025 - 08:47
A university student on a fossil-hunting field trip in Dorset made a stunning discovery: a 145-million-year-old jawbone belonging to a previously unknown mammal species with razor-like teeth. With the help of CT scanning, 3D printing, and expert analysis, the fossil was revealed to be Novaculadon mirabilis, a multituberculate that lived alongside dinosaurs. This is the first find of its kind from the area in over a century, and the fossil’s preservation and sharp-toothed structure are offering new insights into early mammal evolution — all thanks to a beach walk and a sharp eye.
