Why are people of different regions have different looks? like China, Nigeria, India, America etc.?

Answer 1

the reason that people of different regions have different looks is because of the genes. These gense were evolved during the process of evolution, so that the spices that is living in a particular place can manage as per the surrounding they are living in.

This happened not only with humans but with every spieces.

Answer 2

The Earth's environment basically governs the appearence of all living things.

This may not be politically correct, and I myself am African, so just know that I'm not being at all mean, no matter how funny some of these answers sound...

Textured hair and dark skin (sometimes even naturally dry) devloped overtime when in the relatively harsh environment of Africa in African (Americans). In Asia, an extra fold of skin covers the eye due to mainly protection of harsh weather. Those of lighter skin, Caucasians, stemmed from the inhabitants of Africa and overtime, had less and less reason to produce melenin, a substance responsible for skin color. Some people believe that the trait of natural blonde hair is a genetic "defect," but I'm not even familiar with that association.

Diet also plays a HUGE part in appearence, though the basic understanding of that should be obvious. The phrase, "you are what you eat" should be taken in the most literal sense possible...

All of this is what I've decuced, faintly read, or heard from elsewhere. The gist of it makes sense to you, I hope...

Answer 3

People of different regions, although evolved from the same stock has undergone evolutionary changes in response to climate and habitat thereby givinging different races of human being, so special or adopted to their enviromental conditions. Also some times the enviroment alone, segregates clans. In India, almost all the races of people have migrated. Some of them can be even now well recognised. Mixing of races adds to evolution for betterment. It seems genetic make up has an edge over the enviromental conditions.

Answer 4

The look of different regions like China,Nigeria,America, India is different in colour shape and size too mainly due to the climetic conditions of that region. Due to the climetic condition the special effects must be there in the character of gens responsible mainly for the colour,size and the shape of people.The size colour and shape of the people of hilly sections is found different that those of the plain grounds and likewise those of cold area and the hot are also.It is all due to the climate and the plain or hilly area.

Answer 5

racism and antimiscegenationists. In some circles this is known as the "pink monkey syndrome". If someone is different from you he/she is to be feared. If they are sufficiently different, they are killed or enslaved. Under no circumstances are you to mate with them. Hence, the races diverge Attempts to reverse this are sometimes met with extreme violence even today.

Answer 6

Genetic Traits and Adaptation

Answer 7

Human genetics A self-discipline in contact with genetically determined resemblances and alterations between people. Technological advances contained in the visualization of human chromosomes have shown that abnormalities of chromosome determination or structure are fairly difficulty-loose and of many diverse kinds, and they account for start defects or psychological impairment in various persons besides as for countless early spontaneous abortions. progression in molecular biology has clarified the molecular structure of chromosomes and their constituent genes and the strategies in which change contained in the molecular structure of a gene can convey about a disease. challenge about attainable genetic harm by environmental brokers and the attainable risky outcomes of unsafe aspects contained in the ambience on prenatal progression has also inspired study in human genetics. The clinical aspects of human genetics are starting to be fashionable as nonhereditary motives of unwell health or early demise, which incorporates infectious disease or dietary deficiency, have declined, a minimum of in additional suitable international places. ------------------- it is basically the first paragraph from the referenced internet website. It supplies a sturdy description of the excuses behind the alterations between people from diverse aspects of the international. i wish it is sensible.
