I was depressed this morning because nothing in my life seems certain these days. This includes money, dating, my health (both mental and physical), and you know, a general questioning of my overall purpose in life (?). Feeling mad overwhelmed, I forced myself to pull out my camera and do something creative. Life is still triflin’, but I do feel a lot better, and more equipped with the strength to take it all on. “Art washes away the dust of everyday life.” - Picasso
Also, I have got to start finding more models to shoot and collaborate with, because I hate messing with tripods. They are a pain in the ass 😅NYC folks- DM to set up a shoot ✨
CROP-CROP CROP-CROP TOP !!! Crop tops known to be fun fashion look which is showcased by women are no more the only proud possession of their wordrobe — as the #alphamale do take the opportunity to flaunt their abs. #justinbieber ignited this debate when he was spotted on the beach while wearing a cropped white tank top.
It's no more any big deal for men to wear crop tops — this was once even considered a trend — #Bieber , as one of the biggest male celebrities of this decade, has made a major #fashionstatement by sporting one. This statement made wearing crop tops mainstream for men. The transgressive trend for men to wear crop tops may only now be on the cusp of conventional culture, but it’s been present in the #gay community and #club culture for decades.
S.C.I.E.N.C.E - DAY🕵️ 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. We consider the human race that is spread across the globe as members of a single species, Homo sapiens, but we certainly don’t all look the same. From language, culture and clothing to height, eye shape and hair color, human beings have many things that make us unique from one another.
However, if we all belong to the same species, shouldn’t our basic skin color be the same? Why are some people fair and others dark? "MELANIN DEFINITION"
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. The two forms of melanin are called eumelanin and pheomelanin. Eumelanin comes in primarily brown and black hues, while pheomelanin appears as red and yellow hues. It is produced by a specialized group of cells called melanocytes.
S.C.I.E.N.C.E - DAY🕵️ .......... *How does it affect our Skin Color?* Before we can find out why we have different skin colors, we should first understand the basic science behind our skin. First of all, there is no such thing as “black”, “white”, “red”, or “yellow” in terms of skin color. There are simply mixtures of colors and variations, depending on your genetic makeup.
For example, someone with very dark skin would primarily produce eumelanin, while pale-skinned Europeans might produce a majority of pheomelanin. Perhaps more importantly, the size and number of melanin particles is also a factor in determining skin color. Melanin is produced in specialized cells called melanocytes, but these do not behave the same way for all people. Some people naturally produce less melanin, which means less pigment and lighter skin. Other people possess fewer melanocytes than normal, which also results in less overall pigment and lighter skin. Clumps of melanocytes in fair-skinned people often appear as freckles, while areas lacking freckles will usually be extremely light. 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.
S.C.I.E.N.C.E - DAY🕵️ .......... *Why Are There Different Skin Colors?* To answer that question, we need to turn back the clock about 1.2 million years or so, when “humans” as we know them began losing their fur and walking erect. Since that point, humanoids have been susceptible to the endless process of natural selection, in which favorable genes promote traits that aid survival, and are thus passed along to successive generations. The most important adaptation that early humans developed? The ability to survive sunlight.
In the heart of sub-Saharan Africa, where it is believed that all humans originally came from, the sun is incredibly intense. For early humans living near the Equator, they were getting pounded by sunlight and radiation all year long, and excessive UV radiation can be very harmful to the skin, resulting in cell mutation, increased risks of cancer, and destroy essential vitamins in the body. Conveniently enough, melanin functions as a shield against ultraviolet radiation, thus protecting the cells from the many dangers of excess exposure. Over thousands of generations, as our ancestors’ skin became more and more exposed to sunlight, humans adapted to have higher levels of melanin, particularly eumelanin, to block those harmful rays. Imagine this video… but in reverse.
One of the key vitamins for human health is vitamin D, which helps the body absorb calcium and other minerals that are essential for bone growth and repair. Unfortunately, our primary source of vitamin D is linked to sunshine; the radiation actually helps to synthesize vitamin D in the skin, in conjunction with another chemical. Thus, for people living in colder climates, or areas which experience darkness for extended periods of time throughout the year, having dark skin meant blocking that radiation, and thus lacking in vitamin D.
S.C.I.E.N.C.E - DAY🕵️ ......... *The Genetic Side of Things*
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. When those anomalies result in higher survivability, they are passed on to one’s children. 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!
S.C.I.E.N.C.E - D.A.Y 🕵️ ...........For example, the melanocortin 1 receptor gene is what determines whether the body produces eumelanin and pheomelanin at all, and by comparing the genetics of chimpanzees and early humans, we see that this particular gene was positively selected in a major way once apes lost their fur. Similarly, the KIT ligand gene and Agouti signaling peptide gene control eumelanin production, and were positively selected in populations that moved out of Africa, to areas where less eumelanin (brown and black pigment) was needed.
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. If we want to make a better world, we need to focus on what unites us, not what makes us different. After all, skin color really is only skin deep!
