It is already pretty well known that Melanin can function something like a cosmic sunscreen. That’s why when melanated people go outside in the sun we absorb the energy from the sun and store it for later use. While non-melanated people can not sustain continued exposure to the sun without physical deterioration.
Well, according to many reports, the planet is heating up. This phenomena is called Global Warming. There are endless suggestions as to why this is happening but the point is, in the coming years the sun will penetrate earth’s atmosphere more and more. Meaning the sun will seem to shine brighter, and the temperature of the planet will continue to rise.
Unless you have sufficient levels of internal and external Melanin you will not be able to adapt to the new environmental conditions. The Melanin found in Black and Brown people around the world will aid in adapting to the increased energy from the sun. Melanin absorbs energy. Without enough melanin in your biological circumstance living on earth will become the equivalent of living in hell.
The following is an abstract of Alexandre Roulin’s “Melanin-based Colour Polymorphism Responding to Climate Change“:
“Climate warming leads to a decrease in biodiversity. Organisms can deal with the new prevailing environmental conditions by one of two main routes, namely evolving new genetic adaptations or through phenotypic plasticity to modify behaviour and physiology.
Melanin-based colouration has important functions in animals including a role in camouflage and thermoregulation, protection against UV-radiation and pathogens and, furthermore, genes involved in melanogenesis can pleiotropically regulate behaviour and physiology. In this article, I review the current evidence that differently coloured individuals are differentially sensitive to climate change. Predicting which of dark or pale colour variants (or morphs) will be more penalized by climate change will depend on the adaptive function of melanism in each species as well as how the degree of colouration covaries with behaviour and physiology.
For instance, because climate change leads to a rise in temperature and UV-radiation and dark colouration plays a role in UV-protection, dark individuals may be less affected from global warming, if this phenomenon implies more solar radiation particularly in habitats of pale individuals. In contrast, as desertification increases, pale colouration may expand in those regions, whereas dark colourations may expand in regions where humidity is predicted to increase.
Dark colouration may be also indirectly selected by climate warming because genes involved in the production of melanin pigments confer resistance to a number of stressful factors including those associated with climate warming.
Furthermore, darker melanic individuals are commonly more aggressive than paler conspecifics, and hence they may better cope with competitive interactions due to invading species that expand their range in northern latitudes and at higher altitudes.
To conclude, melanin may be a major component involved in adaptation to climate warming, and hence in animal populations melanin-based colouration is likely to change as an evolutionary or plastic response to climate warming.”
In other words, Melanated people maintain the biological circumstance required to adapt to the phenomena scientists call “Global Warming”.
