Final answer:
The origin and spread of modern humans are supported by fossil records, genetic studies, and archeological artifacts, which collectively point to Africa as the cradle of human evolution and document the subsequent global migration.
Step-by-step explanation:
The evidence that supports the origin of anatomically modern humans in Africa around 200,000 years ago and their subsequent global spread, involves fossil records, genetic studies, and archeological artifacts. Fossil records show a chronological progression of human ancestors in Africa, while genetic studies reveal a high level of genetic diversity in the African continent, indicating a longer period of human genetic evolution. Interestingly, all human genomes tested outside of Africa have close ties to the genomes of African populations. Archeological artifacts and traces at various sites support the movement of early humans out of Africa, showing a pattern of migration that aligns with the theory that modern humans spread globally from an African origin.
Thus, the strongest options supporting this theory are A) Fossil records, B) Genetic studies, and D) Archeological artifacts. Ancient texts (C) are not considered reliable scientific evidence for this prehistoric period.
