For millions of years, Earth belonged to the dinosaurs — and according to one scientist, their dominance may have done far more than shape the prehistoric food chain. It may also have fundamentally altered the biology of mammals, including humans, by pushing our ancestors away from long life and toward rapid reproduction. This provocative theory comes from João Pedro de … [Read more...] about A Scientist Says Humans Were Meant to Live So Much Longer—Then the Dinosaurs Ruined It

Humans Nearly Went Extinct 800,000 Years Ago, DNA Study Reveals
A groundbreaking genetic study suggests that human ancestors came dangerously close to extinction nearly 800,000 years ago—reduced to a shockingly small population that may have reshaped the course of human evolution. Published in the journal Science, the research indicates that as few as 1,280 breeding individuals may have survived during a prolonged population collapse … [Read more...] about Humans Nearly Went Extinct 800,000 Years Ago, DNA Study Reveals
“Dinosaur Highway” Discovered in England Reveals 166-Million-Year-Old Tracks
A chance observation in a quiet English quarry has uncovered one of the most significant dinosaur track sites ever found in the United Kingdom—offering a rare and vivid glimpse into life during the Middle Jurassic period, 166 million years ago. The discovery, announced by researchers from the University of Oxford and the University of Birmingham, began last summer when a … [Read more...] about “Dinosaur Highway” Discovered in England Reveals 166-Million-Year-Old Tracks
The Balearic Cave Goat: The Only Goat With Forward-Facing Eyes and a Cold-Blooded Metabolism
The Balearic cave goat, scientifically known as Myotragus balearicus, was one of the strangest mammals ever to exist. This remarkable species lived on the Balearic Islands and vanished around 4,000 BCE, leaving behind fossil evidence that continues to astonish scientists. What sets this animal apart is that it combined traits never before seen together in a mammal. A Goat … [Read more...] about The Balearic Cave Goat: The Only Goat With Forward-Facing Eyes and a Cold-Blooded Metabolism
If Humans Die Out, Octopuses Already Have the Chops to Build the Next Civilization, Scientist Claims
Earth is no stranger to extinctions. As scientists have discerned from fossil records, species on Earth have already passed through five mass extinction events in the planet’s lifetime, including the last mass extinction roughly 65 million years ago that wiped out the dinosaurs. Now, scientists believe we might be in the midst of another. Humans’ impact on biodiversity—via … [Read more...] about If Humans Die Out, Octopuses Already Have the Chops to Build the Next Civilization, Scientist Claims
