Anthropologists in the United Kingdom suggest that blue eyes could have an additional advantage in low-light conditions. Kyoko Yamaguchi and her student Faith Erin Cain from Liverpool John Morris University came to this belief, relying on 39 volunteers, 25 people who had some degree of blue eyes. 14 people with varying shades of brown eyes underwent two 30-second tests under low light intensity. Although this study is preliminary and relatively small, it supports the theory that loss of pigmentation in the iris was a trait selected in some populations to maximize vision in low-light environments. Lighting, according to the article published in the scientific magazine "sciencealert". It is worth noting that all irises consist of a pair of "canvases" scattered with varying amounts of proteins such as "melanin", and since people with dark eyes have fewer cases of diseases such as cancer And macular degeneration, an iris full of melanin is likely to confer a degree of protection. Just as humans were beginning to settle down, a mutation occurred in one individual in a gene associated with albinism, giving their body the ability to dilute the level of melanin by a very high percentage in a specific location, in "Their eyes", then passed on to our ancestors throughout the ages, and today it is found in hundreds of millions around the world, according to the study. Satellites record a scene of "the bleeding of the earth"... pictures and video. It is possible that the explanation of the reason for the continuation of this mutation until now is complex, as it may have been They are associated with beauty, they help improve low moods in winter, or they may take up less of the body's resources to build in unfavorable conditions.
