Of course we know that much of human development is biologically defined; however, culture also influences how human life is developed. The first aspect of childhood development that comes to my mind is nutrition. Because various cultures among the various nations of our planet are each very different from one another, we know that the provided nutrition also differs from culture to culture.

As some cultures are wealthy, others are in poverty. The factor of monetary opportunity greatly affects how a child is developed. Those who are not as financially fortunate may struggle…show more content…
The production of vitamin D is favors those with lighter skin, with less melanin and UV radiation.

Studies suggest that prior to 1 mya, our ancestors lived mostly in Africa with lots of melanin/dark skin, but as they migrated to more northerly latitudes, their skin lightened over time. Melanin also affects the function of folic acid within our bodies which is known to help synthesize and repair DNA, thus aiding cell division and homeostasis. High levels of melanin and dark skin prevent folate depletion from too much UV radiation, which helps prove that natural selection maintained dark skin in regions with high UV radiation.

As proven in the study of anthropology, genetic variation occurs across the human population regardless of “race.” R.C. Lewontin was the first to document this theory and many scientists since have agreed such as Franz Boas who disproved “race” through the study of skull shape. Scientists believe that the human race evolved over time from an earlier similar species and that over time clines occurred (the gradual change in phenotypic characteristics from population to population). Among groups which many
