The migration routes of Homo sapiens reveal that they went through many environmental and physical challenges but adapted everything much quickly in comparison to the other animals. The evolution allowed other species also to adopt these changes but it took them a long time to fit in the new environment, a sub species of a species adopted the new and the previous one could not, but Homo sapiens invented ways and tools to combat and evolve much quickly. It included their living, dietary needs, clothing and much more.
