Final answer:
Early humans are believed to have originated in Africa and then spread out to different continents. Genetic and fossil evidence supports the idea that Homo sapiens evolved in Africa before migrating to other parts of the world. Recent archaeological finds have provided new insights into the settlement of the Americas.
Step-by-step explanation:
Early humans are believed to have emerged from Africa and then spread out to populate different parts of the globe, interbreeding with Neanderthals along the way. The genetic and fossil evidence supports the theory that Homo sapiens, anatomically modern humans, developed in Africa more than 100,000 years ago and migrated to other continents. While the Americas were settled later and do not have the oldest art, recent archaeological finds have challenged previous beliefs about the timing and method of their settlement.
