Skin color is due primarily to the presence of a pigment called melanin, which is controlled by at least 6 genes. However; the relationship between skin pigmentation and photoprotection is still being investigated. Why Are There Stones Alongside Railway Tracks? The two forms of melanin are called eumelanin and pheomelanin. The important thing to remember about skin color is this—every human on this planet shares a common ancestor from about 200,000 years ago in the heart of Africa, and they definitely had dark skin. From language, culture and clothing to height, face shape, and hair color, human beings have many things that make us unique from one another. The melanin pigments are produced in a specialized group of cells known as melanocytes. When melanocytes produce melanin, it is deposited into the epidermal cells where it gives our Skin its color. Melanin is produced by melanocytes,  a type of cell located in the basal layer of the epidermis. Arch Dermatol. OUR SCIENCE Explain that the amount of melanin is what makes skin darker or lighter 3. John Staughton is a traveling writer, editor, publisher and photographer who earned his English and Integrative Biology degrees from the University of Illinois. Melanocytes are also present in and responsible for coloration to the hair and the irises of our eyes. The expression of pigment is controlled by six main genes in the body, and this genetic makeup is largely determined by your parents and the generations that came before them. That’s how natural selection works; as small blips, errors, additions, and mutations to genetic structure occur, we see genetic anomalies in terms of skin color expression, etc. Melanin in human skin is the ingredient that produces skin color. Melanin (/ˈmɛlənɪn/ ( listen); from Greek: μέλας melas, "black, dark") is a broad term for a group of natural pigments found in most organisms. Two types of melanin are found in the skin and hair, the brown/black melanin, eumelanin, and the red melanin, pheomelanin [26 ]. However, the core reason for the development of dark skin is contentious. Melanin's role is to protect DNA in body cells from sun damage. The majority of genes that control pigmentation have now been identified, and we can trace the progression of skin color across the world—and throughout history! Skin Color Distribution (Photo Credit: anthro.palomar.edu). Perhaps most importantly, the amount of melanin is also a factor in determining skin color.

Other people possess fewer melanocytes than normal, which also results in less overall pigment and lighter skin. Melanin is made within small membrane–bound packages called melanosomes. Melanin is the pigment that determines skin colour as well as hair and eye colour. The relative coloration of the skin depends of the amount of melanin produced by melanocytes in the stratum basale and taken up by keratinocytes. It is the amount of melanin that those melanocytes produce that varies and gives rise to variations in skin color. We hypothesize that human skin contains enzymes that degrade melanin and these enzymes can be used to reduce skin color. How Does The Human Body Repair A Fractured Bone?

A dark brown coloring found in the body, especially in the skin and hair. Our skin color is determined by a pigment called melanin, and while everyone has melanin (both fair and dark-skinned people), it comes in different forms and ratios. Having more melanin makes the skin darker, while less of it results in lighter skin. Our world is a wonderfully diverse and beautiful place, with millions of species of animals and plants, capped off by the most dominant species human beings. People can temporarily change the color of their skin by tanning (or getting sunburnt), which essentially stimulates the production of melanin and inflames the area to protect against adverse UV exposure. It provides some protection again skin damage from the sun, and the melanocytes increase their production of melanin in response to sun exposure. When the skin is exposed to the sun, melanocytes increase melanin production and this causes the Skin to become Darker and tan. We consider the human race that is spread across the globe as members of a single species, Homo sapiens, but we certainly dont all look the same. What is the function of melanin? Reverse adaptation occurred as humanity sprawled across the planet into different climes, and eventually, their skin color faded over the course of many generations.

Melanin synthesis in melanocytes is only the first phase of melanin metabolism. Melanin is produced by melanocytes , a type of cell located in the basal layer of the epidermis . Melanin is produced by melanocytes through a process called melanogenesis. This melanin comes in the form of cells called melanocytes. Pituitary tumors and spiked estrogen levels that occur during Pregnancy cause the pituitary gland to produce more of this hormone. In the early 1990s, the evolution of skin color was regarded by many of her peers as an intractable problem. It is a dark biological pigment which occurs throughout the species universe and found not only in skin, but hair, feathers, scales, eyes, and a number of internal membranes. Melanin production is regulated by a peptide hormone from the pituitary gland and known as the melanocyte-stimulating hormone. Why Do We Make Those Random Drawings During Boring Lectures?
