Question

Quizplus · Accepted Answer

The replacement model, also known as the out-of-Africa model, suggests that modern humans first evolved in Africa and then migrated into other parts of the world, replacing all earlier populations of Homo species such as Homo erectus and Homo neanderthalensis. This model is supported by genetic and fossil evidence, indicating that modern humans have a common African ancestor and that non-African populations show less genetic diversity than African populations. Therefore, the best choice is A, which describes the replacement model accurately. B, C, and D are incorrect because they propose alternative models that are not supported by the majority of scientific evidence.
