Not all Mesozoic mammals were vulnerable to dinosaurs. Fossils from China reveal that Repenomamus could consume small dinosaurs in Early Cretaceous forests. One species was named Repenomamus giganticus. Repenomamus was unusually large for a mammal of the Cretaceous, approximately 145.5–65.5 million years ago. While most mammals […]
Woolly mammoths became extinct approximately 4,000 years ago. Research suggests that the last populations carried genetic mutations that may have reduced their ability to adapt to environmental change. Woolly mammoths once inhabited North America and Siberia […]
At the time of this report, a Harvard research team proposed creating a mammoth–elephant hybrid embryo within approximately two years. Through genetic engineering, the project aimed to restore traits of woolly mammoths, which became extinct around 4,000 years ago. Speaking before the annual meeting of the American Association for the Advancement of Science (AAAS), Professor George Church […]
