Research Unplugged: The mutation that became white skin

- Опубликовано: 25 мар 2012
- In this video clip, Dr. Keith Cheng describes the work of another Penn State researcher, Nina Jablonski, suggesting a correlation between skin color and the strength of sunlight across the globe.
The evolution of differing skin colors arose as our bodies' adaptation to varied climates and levels of UV exposure, explains Cheng, Professor and Chief of the Division of Experimental Pathology at Penn State Hershey College of Medicine and Co-Director of Penn State IBIOS Bioinformatics and Genomics graduate program.
This brief clip was excerpted from Cheng's Spring 2012 Research Unplugged talk titled, "More than Skin Deep: Solving the Genetic Mysteries of Skin Color."
But eskmos are brown
Thank god for melanin
God's not real, wouldn't except you to know that though.
prove it!
dawn khader *expect
dawn khader ridiculing someone while putting except instead of expect 😂 great job bozo
Why? Each skin color around the world has served it’s purpose to help the human race evolve. And sometime in the distant future we’ll end up all looking roughly the same.
This doesn’t make sense if it only affected the skin why do people have different skeletons. We coulda have different skin but same bones. I guess the mutation went through to the skeleton or maybe I’m wrong don’t know
BLACK IS BEAUTIFUL😎😎😎
Nature Lover i love black women the most
and that why black male prefer white womens..
Many of my forefathers haven't left Europe and they are still dark chocolate throughout the thousands of years.
Misfit Pain Try to fit in Misfit, I use to rock the LAMBS-SHEEP Afro but not now, therefore, I can't be Centric either.
By the way, you do realize that this is not my video? You do realize that Dr. Keith Cheng is fully functioning on his own thoughts as a world renown Geneticist?
Indian Albinos
Albinos from South Asia(Indian Sub continent)//
It's not a thought for lighter skin, its is the reason for lighter skin.
Thank Ahmen for bronze Genetics.
Been looking at menetellect I see.
Whites evolved out of darker skinned caucasoids of western asia who predate them. So called "whites" evolved in areas like Pakistan which to this day have both darker skinned caucasoids alongside light or white skinned caucasoids.
Herbal Shaman You're trailing off on a different tangent comparing Europeans to Africans.
Check the definition of the caucasoid race. Caucasians of western Asia namely places like Pakistan, Afghanistan, Iran and the Arab countries are caucasoid yet darker skinned and they predate the caucasoid of Europe. That is why you find both darker and lighter skinned caucasoids in western Asia because light skinned caucasoids mutated out of darker skinned ones and not the other way around.
The sp called "indigenous" people of India you speak of are australoid which some scientists classify as "archaic caucasoid".
The caucasoid element in India is introduced not via Europe but via places like Pakistan and lower central asia. These are the people from whom the light skinned caucasoids mutated out of.
Blonde hair appears in the human genome at around 11,000 thousand years so this is likely the time when so called "white" people as we know them, appeared.
This is bullshit, otherwise the Eskimos would have light skin.
+The God of Zeus Eskimos gets Vitamin D through whale, seal, and walrus. Therefore, there is no need for Eskimos to have white skin to survive.
dpinckney75 Exactly. Then, lack of sunlight didn't cause us to "evolve" white skin.
it's bullsh*t because you hate to think of yourself as a mutation, even tho the mutation is only 1%

Yes it does come from natural selection because natural selection is just a random mutation that's able to survive in a random environment.
The lack of melanin allow them to survive better in the northern countries where there's less sunlight.
People with melon in a skin can survive in northern areas to but it's better for southern areas where they have more sunlight because the melon produce vitamin C.
Mark Donald, it's not good to have pale skin in Israel, which has the highest rate of skin cancer in the world when it comes to pale skin people.
I thought certain people who stayed in Africa while the others left the continent were mutated to have dark skin mutation for protection from uv light
Herbal Shaman wrong wrong and wrong eeeeeh
Herbal Shaman albinos can come from any race there’s black and Asian albinos which doesn’t make em white they are still black and Asian it just their skin has lost or isn’t producing melanin albinos are actually a bit different from white people they are more prone to skin cancer than whites. Whites are there own thing. Ps white can also have albinism.
I believe in God, not Evolution
Ray I feel sorry for you.
Light skinned this dark skin that. Just drop these worthless speculative so-called research and prove to the world that you can make real contributions that will improve the lives of present and future generations.
thank you, finally a reasonable comment
Thats bs i was raised on the north and im not white
Victor Herrera That’s......not exactly how it works.
The Bible is a lot of Hebraic/ancient middle eastern creation mythology and tribal myth. According to Biblical mythology the European peoples are descendants of Japheth, son of Noah. The dark-skinned ethiopics are descended from Ham, who was cursed by noah and God for seeing Noah passed out and naked, and then laffed and mocked his father. As a result these Hamitic peoples were cursed with dark skin and fated to be the servants and slaves of his lighter-skinned brothers. Sooooo... it must suck bigtime to be you people!
If it makes you feel any better, the ancient Greeks believed that the Sun came too close to Eartha and fried the skin of those people living in the African deserts and savannahs.
1) All the Abrahamic religions copied, plagiarized, and used knowledge gained from the Kemetic spiritual system as the basis of their religions. Creator of the bible Ptolemy II Philadelphus white FAKE pharaoh... It's all Greek 1st Maccabees removed from the KJV, read Dr. Joseph Yahuda Hebrew is Greek and they created Arabic. Albert Perry DNA father of ALL MEN Y chromosome dated 340,000 yrs, that PREDATES fictional adam ( it was ATOM) by 160,000 yrs
2) LacusCurtius • Diodorus Siculus (:90 - 21 B.C.) The Library of History, Books II.35 - IV.58, Translated by C.H. Oldfather, Harvard University Press, 2000
On the Ethiopians who dwell beyond Libya and their antiquities (Book III, chaps. 1-7) Now the Ethiopians/Egyptians, as historians relate, were the first of all men and the proofs of this statement, they say, are manifest. For that they did not come into their land as immigrants from abroad but were natives of it and so justly bear the name of “autochthones” is, they maintain, conceded by practically all men; furthermore, that those who dwell beneath the noon-day sun were, in all likelihood, the first to be generated by the earth, is clear to all; since, inasmuch as it was the warmth of the sun which, at the generation of the universe, dried up the earth when it was still wet and impregnated it with life, it is reasonable to suppose that the region which was nearest the sun was the first to bring forth living creatures
3) Middle East used to be called North Eastern Africa - with the "Middle East" term coming on later to divide and lead to a lot of other issues that never were present before when those nations in the current "Middle East" were considered African nations... How the Middle East was created, after the defeat of the Ottoman armies. The result, the Sykes-Picot Agreement in 1916! To say ppl have olive skin tone ( GREEN), isn't RIPE, so ripe olives are BLACK!
4) SOME INTERESTING FACTS ABOUT MELANIN; 666 this is OUR CURSE relates to the carbon atom, and man. Carbon-12; one of 5 elements in the human DNA is composed of 6 protons, 6 electrons and 6 neutrons, which equates to 666.
It’s chemical structure allows no energy to escape.
It’s the perfect absorber of light and all energy frequencies.
Melanin is abundantly present in the inception of life, there is a melanin sheath covering both sperm and egg.
It’s found in almost every organ of the body.
Melanin responds to and absorbs light, sound, [in the form of music] and electrical energy and uses this energy in the body as food and nutrient...it converts light energy to sound and back again to light energy.
Melanin has a direct relationship with light, heat, radiation, laser waves, radio waves, TV waves, magnetism and electrical currents.
Melanin has a direct relationship with light, heat, radiation, laser waves, radio waves, TV waves, magnetism and electrical currents.
Melanin counteracts stress, viruses and bacteria, improves the quality of sleep and regulates biological rhythms. It may even help protect against cancer and reduce the risk of heart disease.
The melanin in a new type of fungi is ‘eating’ radiation at Chernobyl...melanin can absorb a great amount of energy without producing large amounts of heat because it can transform the harmful energy such as radiation.
The pineal gland controls the flow of melatonin during the night which allows us to communicate with internal memory pools and other dimensions.
The melanin content in the inner ear is also important, increased melanin increases hearing frequencies.
Melanin absorbs light rays and stores them so they can be used the energy later on.
Melanin is like a battery - through the day, sunlight charges the melanin in the pineal gland where it is stored and released at night during sleep.
Melanin is an extremely stable structure which resists most experimental analysis by man.
It is also the site of tissue repair, regeneration and infectious diseases.
Its ability to undergo many chemical reactions at once is what scientists call, ‘oxidation-education reactions’.
The pineal gland secretes melanin during times of relaxation and visualization. As we are created by electromagnetic energy - and react to EM energy stimuli around us - so does the pineal gland.
Injection of melanin could make human body radiation resistant
Melanin/melatonin supplements is now a huge industry...can improve sleep, help those who suffer from seasonal affective disorder (sad) - reduces headaches, strengthens immune system, slows down ageing,
On a philosophical plane, melanin is a chemical/biological door.
Lies Noah cursed Caann not Ham. ps some people have suggest that Black people come from Shem. While looking at the Jewish texts there is nothing to suggest that Black people were curse white people made that shit.
youbettergetrealwiti you're correct. Noah cursed Canaan and his descendants.
Deana Nicole Noah was albino
Herbal Shaman Ham's son.
