Scientists just confirmed that our mammal ancestors laid eggs, thanks to a rare fossil preserving a curled-up embryo from 250 million years ago. The discovery explains how one tough creature survived Earth's deadliest extinction event.
A tiny, nearly complete skeleton from Mongolia's Gobi Desert just solved a 40-year mystery about early mammal evolution. The rabbit-sized creature proves that similar features can evolve separately, changing how scientists understand our ancient relatives.

Scientists found a growth mark in an ancient fossil suggesting mammals may have started giving birth to live young 95 million years earlier than previously thought. The discovery could rewrite our understanding of how mammals evolved.
Scientists discovered evidence that ancient mammal ancestors were giving birth to live young 95 million years earlier than we thought possible. The find suggests many traits we consider "modern" evolved far earlier in history than anyone imagined.
A massive study of 5,800 animal genomes reveals evolution follows predictable "highways" rather than random paths. The discovery could help scientists understand where evolution might head next and guide conservation efforts.
Scientists have discovered the first proof that our ancient mammal ancestors laid eggs, solving a mystery that's puzzled researchers for generations. The fossil also explains how these creatures survived Earth's deadliest mass extinction.
Researchers discovered that evolution doesn't wander randomly but follows predictable genetic "highways" laid down over 600 million years. This breakthrough could help scientists predict future evolution and better protect endangered species. ##
Scientists discovered a 252-million-year-old fossilized embryo in South Africa that proves our mammal ancestors laid eggs and reveals how they survived Earth's worst mass extinction. The find marks the first confirmed evidence of egg-laying in therapsids, the prehistoric creatures that gave rise to modern mammals.
Researchers discovered the first confirmed egg from a mammal ancestor, solving a 200-year mystery about how these ancient creatures reproduced. The fossil shows how one tough species survived Earth's worst extinction and paved the way for all mammals today.
Scientists discovered a roadrunner-sized dinosaur in Argentina that's forcing them to rethink how some dinosaurs became miniature. The 700-gram creature proves evolution doesn't always follow a straight line.
Scientists discovered the first confirmed egg from a mammal ancestor, solving a mystery about how tough little Lystrosaurus survived Earth's worst extinction event. The 250-million-year-old fossil shows these creatures laid large, soft-shelled eggs that helped their babies thrive in brutal conditions.
Scientists discovered a 75-million-year-old fossil in Mexico that reveals how tiny mammals outlasted the asteroid that killed the dinosaurs. The finding shows how being small and eating anything helped our ancient relatives survive Earth's deadliest day.
A new book argues we're missing huge opportunities by ignoring evolution's lessons for modern challenges. Understanding natural selection could revolutionize everything from medicine to decision-making.
A nearly complete 90-million-year-old skeleton from Argentina is solving one of paleontology's strangest puzzles. The tiny dinosaur proves these odd creatures shrank before they specialized, flipping evolution theories on their head.
Scientists discovered that butterflies and moths separated by millions of years use identical genes to create similar warning patterns, revealing evolution follows surprisingly predictable paths. This breakthrough could help us understand how species will adapt to future climate changes.
The largest study of ancient human DNA reveals that human evolution has dramatically accelerated since farming began, reshaping everything from disease resistance to physical appearance. Scientists found nearly 500 gene variants that changed through natural selection as our ancestors adapted to revolutionary lifestyle changes.
Cornell researchers discovered milkweed plants have evolved a brilliant new defense mechanism that could revolutionize monarch butterfly conservation efforts. The findings reveal nature's surprising innovation in one of evolution's oldest battles.
Researchers are watching one of nature's deadliest mushrooms rapidly evolve in California, revealing how species adapt to new homes. The discovery gives scientists a rare window into evolution happening right now.
A collapsed cave ceiling in Mexico created a unique laboratory where blind and sighted fish of the same species now live side by side, showing scientists how evolution works in real time. Researchers discovered key genes responsible for eye development by studying this rare natural experiment.
Scientists just found the world's oldest proof that our mammal ancestors laid eggs, tucked away in a South African fossil for 20 years. The discovery reveals how a pig-like creature survived Earth's worst mass extinction.
