Melinine Mutations, and Why we Have Diversity in Eyes and Skin
Skin, it is an important covering for your body. The whole job of our somatic cells is to protect our skin from damage to DNA by UV rays. Contained in our genetic structure are genes with a determinate amount of melanin. It determines the amount of pigmentation expressed in our phenotype. This has caused the separation of many nations.
The question here is why? Looking into our ancestral ties, going back to the chimp-like ancestor, we were likely all very dark pigmented. The ones who carry the largest mutation of inactive genes are those of us with light skin, and blue eyes. For every eye color, and skin color, and hair color that is less than black to dark brown is an inheritance of genes that do not function. This is likely the reason that people who marry a blue eyed person have more brown eyed offspring. Because the DNA will use the functioning genes and pass over the non functional one. When it comes to blue eyes, the lighter they are the more genes that are non functional for m…
