Final answer:
Modern humans evolved in Africa due to changes in climate, diet, and survival strategies. Genetic research supports this theory, showing close ties between human genomes in Africa and the rest of the world.
Step-by-step explanation:
Modern humans evolved in Africa.
Millions of years ago, our distant ancestors descended from the trees, took to walking upright on the land, and gradually evolved into the species we are today. Their evolution was influenced by many variables, including changes in climate, diet, and survival strategies. Over time, humans developed new skills and tools to meet the challenges of endurance and sought better prospects for themselves through cooperation and migration.
Genetic research also supports the theory that humans most likely descended from Africa, as all the human genomes tested outside of Africa had close ties to the genomes of people in Africa. Additionally, there is a genetic variance in Africa that was not found in the rest of the world.
