Fossils reveal that our human ancestors lived alongside the dinosaurs
New analysis of fossils reveals that our human ancestors actually lived alongside dinosaurs for a while before the giant asteroid impact that wiped out the dinosaurs. This finding sheds light on a long-standing debate among paleontologists. The question was whether placental mammals, the group that includes humans, originated during the Cretaceous period alongside dinosaurs or only after the mass extinction event that eliminated them. The new evidence suggests that placental mammals, including our early ancestors, were already present on Earth millions of years before the asteroid impact. This means they must have coexisted with dinosaurs for some time.
