The migration of prehistoric humans to different regions of the globe and the subsequent development of varying concentrations of melanin in their skin exemplify the concept of adaptive radiation. Adaptive radiation refers to the diversification of a single ancestral species into multiple specialized forms, each adapted to exploit different ecological niches. In this case, the different populations of prehistoric humans adapted to the varying levels of sunlight and UV radiation in their respective environments, leading to variations in melanin production and skin pigmentation. This is an example of how natural selection and adaptation can drive the diversification of species in response to different environmental conditions.

Hence, the correct answer is option 4.
