Our ancestors were making stone tools even earlier than we thought—some 700,000 years older. That’s the finding of the West Turkana Archaeological Project (WTAP) team—co-led by Stony Brook University's Drs. Sonia Harmand and Jason Lewis—who have found the earliest stone artifacts, dating to 3.3 million years ago, at a site named Lomekwi 3 on the western shore of Lake Turkana in northern Kenya.
Dinosaurs grew as fast as your average living mammal, according to a research paper published by Stony Brook University paleontologist Michael D’Emic, PhD.
