But their ancient nature (confirmed using several methods, including the dating of stone tools found nearby that were reported on in a second study) suggests instead that early humans spread out around Africa long before our species ventured off the continent.
Triceratops, a name meaning “three-horned face”, is a genus of herbivorous ceratopsid dinosaur that is said to have first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago.
This will be covered in the chapters, Primitive Environment (chapter 9), and DNA (chapter 10).
Third, evolution of living organisms into more advanced life forms by natural selection or mutations.
An early human species with a curious mix of archaic and modern features lived in South Africa just a few hundred thousand years ago, researchers have found.
Dubbed Homo naledi, the species had a small, fist-sized brain similar to that of ancient hominin species that lived millions of years earlier.
