SANTIAGO: An oddball, vegetarian dinosaur with the silhouette of a flesh-ripping velociraptor, whose fossilised remains were unearthed in southern Chile 13 years ago, is a missing link in dino evolution, researchers said on Wednesday. A revised assessment of the kangaroo-sized Chilesaurus, reported in the journal Biology Letters, bolsters a theory unveiled earlier this year that threatens to upend a long-standing classification of all dinosaurs. Dinosaurs were the monarchs of Earth for 160 million years until a space…
PARIS: Humans likely developed large and powerful brains, researchers said Monday, with the help of what is today the simplest of snacks: fruit. Eating fruit was a key step up from the most basic of foodstuffs, such as leaves, and provided the energy needed to grow bulkier brains, the scientists argued. "That’s how we got these crazy huge brains," said the study’s corresponding author Alex Decasien, a researcher at New York University. "We have blown up the quality of our food that we are eating." The study…
PARIS: Half-sized humans who lived 700,000 years ago were almost certainly the ancestors of enigmatic "hobbits" whose fossils were found on the same Indonesian isle in 2003, scientists stunned by their own discovery reported Wednesday.
HELSINKI: US biochemical engineer Frances Arnold on Tuesday won a million-euro technology prize in Finland for her work on "directed evolution", a method of rewriting DNA to improve medicines and develop green fuels.
