La lutte cachée qui a tout changé : pourquoi les dinosaures n’ont eu d'autre choix que de devenir géants
The hidden struggle that changed everything: why dinosaurs had no choice but to become giant
Dinosauria evolution mammals
During evolution, dinosaurs sometimes became monumental. On the other hand, no process led to making them smaller, which could be explained by a kind of environmental competition with mammals.

Fossil Evidence Pushes Back Origin of Live Birth by 90 Million Years

Paleontologists studying a 236-million-year-old cynodont fossil from Argentina say they have found the earliest evidence yet of viviparity (live birth) in the evolutionary line that leads to mammals, pushing back the origin of this reproductive strategy by as much as 90 to 95 million years.

Palaeontologists have named a new species of theropod dinosaur from New Mexico. The dinosaur, Dinevenator robustus, lived around 73 million years ago (Campanian faunal stage of the Late Cretaceous). Researchers identified the dinosaur from a fossil skull bone (a frontal) found in north-western New Mexico. It represents a new genus and species of troodontid. Troodontids

3,500-year-old skeletons challenge what scientists thought they knew about syphilis
Vietnam discovery skeleton
Ancient remains from Vietnam suggest diseases like yaws may have been passed from mother to child thousands of years ago, a form of transmission often assumed to indicate syphilis. The discovery could overturn how scientists interpret ancient infections and complicate the long-running mystery of syphilis’s origins.

A new study has revealed a dramatic decline in Berlin amphibian populations. Researchers report that frogs, toads and newts have declined by more than three-quarters since 1981. Furthermore, scientists found a substantial decline in the city's dragonflies. Their populations have fallen by more than half since 1963. Much of Europe has been gripped by an

Scientists find evidence for two origins of life on Earth

Scientists probing life’s deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share one ancient genetic code, yet have undergone two separate transitions into free-living existence.

King Harold may have lost England by backing the wrong pope
discovery
A forgotten fragment of a lost papal letter is offering a surprising new explanation for the Norman Conquest. England may have backed the wrong pope during a bitter religious power struggle, giving Pope Alexander II a political reason to support William the Conqueror’s invasion. The discovery suggests Harold’s downfall in 1066 was shaped by intrigue in Rome as well as bloodshed at Hastings.

Dinosaurs evolved into some of the largest animals ever to walk the Earth, but a new mathematical model suggests that early mammals may have crowded them out of the ecological niches reserved for the smallest creatures.

240-million-year-old reptile fossil reveals a lost chapter before dinosaurs and crocodiles
predator Brazil Triassic fossil Dinosauria evolution other reptiles
A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles. Its close relatives were previously known mostly from other continents, suggesting these ancient animals spread much farther across the Triassic world than scientists realized.

For 15,000 years, humans and dogs have been changing each other
behavior evolution genetics Homo sapiens mammals
Dogs have been shaping—and being shaped by—humans for about 15,000 years, evolving from early partners of hunter-gatherers into an astonishing range of specialized companions. Across the globe, they adapted alongside people to wildly different environments and needs, from powerful Arctic sled dogs and agile rainforest hunters to high-altitude dogs with genetic traits for surviving thin air. Some were even bred for wool, while others played important spiritual or ceremonial roles.

60,000-year-old ostrich eggshell engravings reveal a surprisingly sophisticated human mind
behavior bird Homo sapiens
More than 60,000 years ago, humans in southern Africa were engraving ostrich eggshells with intricate geometric patterns that appear far more organized than previously realized. Researchers found recurring grids, parallel lines, right angles, and repeated shapes, suggesting the designs followed deliberate rules rather than being improvised. The engravers may even have planned entire patterns in their minds before carving them.

Dinosaurs became giants — so why did they never become tiny?
ecology growth Dinosauria evolution mammals
Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature end of the dinosaur spectrum—and that early mammals may have been partly responsible. While dinosaurs kept mammals from becoming large, small mammals may have returned the favor by occupying ecological niches that could otherwise have supported mouse-sized dinosaurs.
