Question

How have the historic levels of melanin in human population change due to migration

Answer 1

As an AI language model, I do not have access to up-to-date information as I am not connected to the internet. However, based on history, it is known that early human populations living in sunny areas of the world developed more melanin in their skin as a protective measure against the harmful effects of excessive exposure to ultraviolet (UV) radiation. As populations moved to areas with less intense sunlight exposure, they would lose some of their melanin production as it was no longer a necessary adaptation for survival. It is important to note that melanin levels are also influenced by genetics, so the impact of migration on melanin levels would vary by individual and is a complex subject that requires further research.
