This video tells you what happened to all the blacks in China. Skip to 17:07
When you really look at the girl you can tell that something about her makes her different from the northern Asians.
The Blacks were basically bred out of existence, and became certain S. chinese groups and the South East Asians. So much for your Dominant black gene.
C'mon man. You know if everyone who looks alike, or nearly alike, keep fukking each other, their genes will be the dominant in their group until they get with another group who has "black" genes, and that group has access to a wide variety of food as food helps activate your genes and keep them strong, and the black physical characteristics are made to survive the harsh environment of the earth. All this theory you put so much stock in is scary because if you study the sciences, in all of it's fields, you would know nothing is etch in stone, especially history, so you don't put all of your stock in it.
My man, you have to let go of that anger. You're looking like a crazy person.
BTW, people who do these theories keep downplaying how much FOOD may have effected peoples looks changing. If you are constantly moving into a new, harsh environment, your access to food will be scarce because you have to learn the environment to get food which means some days you will be low in protein, and fat. That means your skin will become lighter as melanin is made from tyrosin,and you need fat to keep the system in the skin going throughout the day and to help capture the uv-b, and uv-a light to help make the melanin. Your hair will get longer as you will need something to protect your neck and skull from being too cold. An afro and dark skin can protect you as they protect the skull and the dark skin helps create body heat BUT if you are low in food, your hair won't grow big, and the skin can't create heat and darkness to absorb the sunlight, so the body just makes your skin light and put more energy into making black hair as the hair will protect the skull as well as help generate some type of heat to keep the body, and brain from getting too cold. Making the skin dark takes a lot of energy, and if you are in a cold environment with low resources in food and clothing, the body will just put all of it's energy into some form of protection which is hair. That is why people who stayed in the mountains were so hairy. The jawline asians have can be due to dht from them drinking a lot of tea. Their eyes is most likely from the bushmen who have slanted eyes in southern africa. You can see the Asian like features in Nelson Mandela. There would have been no need to mutate the eyes as it would have been a good thing to have to protect the eyes form the snow.
