Why are blacks in America not as black as blacks in Africa?

It is caused by intermarriage。Because according to the latest evolutionary theories, the genome of organisms.

The change is sudden, not gradual. The genetic mutation must have taken longer than the hundreds of years that blacks have lived in the United States. Therefore,Latitude and light, which are generally thought to be not decisive factors in the physical characteristics of black people.

Most black Americans have patrilineal Europa.

blood, which is a product of slavery. According to the U.S. Gene Bank, 2 out of 3 blacks are of mixed race, making up about 16 percent of the Europa genome on average. As a result, some black Americans have lighter skin tones and more body hair.

In addition, it should be mentioned that,withObamaUnlike black and white Americans, there is a higher probability of being white because blacks have white genes.

Black Americans used to immigrate from Africa, and the way they immigrated was slavery in modern history**。Thus, black Americans are of the same race as black Africans by blood. However, the land in Africa is barren.

Black Africans are mostly thin due to malnutrition.

The head and stomach are huge. The living conditions of black Africans in the United States are relatively good.

Due to the increasing frequency of intermarriage between yellow Americans (Asians and local Indians) and whites and blacks in recent times, black Americans have also been influenced by other ethnic groups to some extent.

Black Americans have played an important role in history. They took an active part in the American Revolutionary War.

and the anti-fascist war, with many achievements. They have also contributed immensely to the economic and cultural development of the United States. They have been a staple of American agriculture.

The wheel of history will not be reversed, let the past pass. The earth is a big family, and skin color doesn't mean anything.

Anyone who has been to the United States will find that the blacks in the United States are slightly whiter than the blacks in Africa, because most of the blacks in the United States exist in the patrilineal Europa ancestry, which is entirely a product of slavery. According toAccording to the data of the U.S. gene bank, about 2 3 blacks in the United States are mixed-race, and the average is about 16% Europa genes, so black people in the United States have lighter skin and more body hair. In addition, the probability of mixed race in the United States is higher than that of white people, especially mentioning that they are different from Obama in that black Americans are more likely to marry white people and have children to become white, because black people have white genes.

The second is due to intermarriage between blacks and whites。This is because, according to the latest evolutionary explanations, the genome changes of organisms are mutated, not gradual, as we usually think. YesThe time required for genetic mutation is certainly greater than the hundreds of years it took for black people to arrive in the Americas, so we usually think that latitude and light are not the decisive factors in the physical characteristics of black people.

Then there is the fact that those black people in the United States have immigrated from Africa in the past, and the way of immigration is mainly obtained by historical slaves**Therefore, black Americans belong to the same race as black Africans in terms of blood. Due to the barren land in Africa, most of the black Africans are thin, malnourished, and have large heads and stomachs, but the living conditions of the black Americans are relatively better. <>

Due to the increasing frequency of intermarriage between yellows, whites and blacks in the United States in recent years, black Americans have also been genetically modified by other ethnic groups to a certain extent. They have also contributed greatly to the economic and cultural development of the United States. In fact, the earth is a big family, and the black and white of the skin color does not mean anything, and mutual equality and freedom is what we ultimately pursue.

Maybe it's because the ultraviolet rays in the U.S. aren't as strong as in Africa.

Because black Americans and black Africans are genetically different, they are not so black.

Because their genes are different, their skin color will also be different.

Because this thing has something to do with their bloodline, their blood bricks have been diluted.

Hello dear. The difference between black Africans and black Americans: 1. There are obvious differences in appearance: Black Americans and black Africans also have a lot of differences in appearance.

And because the black American has some European blood, his nose is taller, his eyes are inward, and his facial features are more three-dimensional. 2. There is a difference in physical fitness, and at the same time, physical fitness is not the same as a stool, because after hundreds of years of intermarriage, the overall quality of black Americans is better than that of their African compatriots. This is determined by the environment in which they live, and it is also caused by the genes of their ancestors, in fact, at the beginning of the slaves, natural selection has been carried out, although it is very cruel to refer to the grandchildren, but in fact, the group of blacks with poor physique have disappeared into the sea and mines.

3. The difference in cultural quality In fact, when talking about black Americans and black Africans, we can't ignore one point, that is, the level of education, because the general environment of black Americans determines that their education level is generally higher, while black Africans, unless the family is particularly good, most of them may only receive a little education, and some black Africans may not have formal education.

The reproduction rate of blacks is terrible, and our country should be vigilant! Reduce the number of black settlements as much as possible.

That's because black Africans are relatively pure-blooded blacks, and many black Americans have some mixed race, which will have some characteristics of other races, and there are also some black people among Native Americans, and Indians who look darker, Indians belong to the yellow race, and of course they are different from black Africans.

There are two main reasons for the difference in appearance between black Americans and black Africans:

1. Changes in geographical location. With less light and less eumelanin deposition, the skin tone becomes lighter; The latitude becomes higher, the temperature is lower, the oxygen supply to the brain needs to be warmed, the nasal passages become larger, and the bridge of the nose becomes higher.

Second, the mixing with the white Indians exacerbated the change in appearance.

The United States is a country founded by the British, who are a mix of Germanic and Celtic peoples, all of whom are Caucasian; The high secretion of demelanin hormone makes black Americans have light-colored pupils, and even white ** blacks; The black and Indians are of mixed race and are well understood, and the skin tone will become lighter. For example, British actor Wentworth Miller; "Queen of Dolphin Sounds" Mariah Carey.

When slaves. Breeded by slave owners, such as allowing strong slaves to reproduce. Triangle**, the slaves with poor physique all died, and the strong ones went to the Americas.

First of all, blacks and yellows, like many branches, have different physical characteristics.

Secondly, there are more black Americans than in the slave trade back then, and it is only a place in the vast Africa.

Thirdly, blacks have come to the United States, especially in recent years, and there has been an increase in the number of mixed-race opportunities.

Finally, the U.S. has a good nutritional status.

To sum up, it is the answer to the landlord's question.

It's too simple, Americans, there are blacks, Caucasians, after several generations, more than a dozen generations of blacks and Caucasians mate, the black genes produced have changed, and the principle is here.

Because almost all the blacks in the United States were sold to that continent when they sold black slaves, they experienced reproduction with whites, and they were also affected by factors such as climate, so they would be more or less different from the primitive Africans.

Black people in the United States are very jealous of Asians, and they are discriminated against by white people, but they often bully Chinese people, especially those with language difficulties.

Culture determines the spiritual outlook, and the spiritual outlook affects aesthetics and appearance, that is, culture rewards the appearance it thinks is beautiful, which is the cultural selection theory. For example, Jews and Arabs are of the same descendant of the Semertes, but due to cultural differences, the former not only evolved into the smartest people, but also many handsome men and beautiful women!

Black Africans are pure blacks. At least 60% of black Americans are born to white American women, and they are still black. But in appearance, it is slightly different from pure blacks.

How rich is the United States, but what about Africa? Do you say that a woman who takes care of it and a woman who doesn't care can be the same? What's more, black Americans are still hybridized! This question has to be asked, the brain is wat!

Most of the ancestors of black Americans were slaves who were sold across the ocean through the trade of black slaves. They are slaves and tools for white people. As a result, their offspring are all hybrids. Its physiognomy, of course, is different from that of the African natives.

There are a few black Africans who are well-fed, and the ones who are well fed are European colonial mixed-race hybrids, just like black Americans.

Living in the United States, one is the environment, most of the time is to avoid the sun, and sunscreen and the like, the second is maintenance, which is maintained in Africa, and the third is mixed-race, in the United States, it looks like a black person, but more than ninety percent are not a single bloodline.

Black Africans are mostly purebred. Some of the black and white Americans are dressed in a variety of ways.

When it comes to climate change alone, many black Americans have high noses, which is caused by the cold weather in the United States.

The same is that in both backward and developed countries, the society is brought chaos, disease and poverty, and high crime rates.

I really don't know what the difference is. I don't know why. What is the obvious difference between black Americans and black Africans, and who knows what? Different.

Black Americans have been crossed with other races to get to where they are today!

Summary. Black Africans, compared to black Americans, are shorter, darker, and have more collapsed noses.

Black Africans, compared to black Americans, are shorter, darker, and have more collapsed noses.

Blacks and whites in the United States have been intermarried for hundreds of years, and the crystallization of love between two people with different skin tones is influencing each other, and their offspring are usually brighter and blacker, and their facial features will be more three-dimensional and good-looking compared to blacks who are not native to Qingjizhou. Because of the different environments, the hair of their offspring is not as coiled as the hair of black Africans, and the body hair on their bodies is relatively less vigorous.

Due to historical reasons, the blacks who can remain in the United States are all physically fit and genetically good. Because of the quick argument, they entered as a trafficked character, and the frail and sick Mu Xiao had already been eliminated on the way to the sea. So there is a certain difference in physique between black Americans and black Africans.

Problem description: Some people say that Africa is the homeland of black people. However, many players in the NBA basketball team in the United States, such as Jordan, are black, can you explain why?

Analysis: After the opening of new shipping routes, capitalist countries (Portugal, Spain, Britain, France) successively embarked on the road of colonial expansion and colonial plunder.

Seeing that it was profitable to transport blacks from Africa to the Americas for sale, European capitalists joined the ranks of criminal slaves.

They set out from Europe and sailed to Africa: in Africa they captured blacks by all sorts of vile means and shipped them to the plantation owners of the Americas, and then they brought back to Europe the gold, silver, and industrial raw materials of the Americas. Because the route has a triangular shape, it is called it"Triangle**".

The Triangle brought a lot of blacks to the United States, and the United States said that every baby born in the United States is an American. Jordan was born in the United States, so he is also American.

Black Americans and Black Africans are two different concepts, and their main difference is their identity and cultural background.

First and foremost, Black Americans refer to black people who were born or live in the United States. Their ancestors may have been enslaved from Africa to the United States, or they may have immigrated to the United States later. Black Americans have historically experienced unequal treatment such as slavery, segregation, and racial discrimination, which has had a profound impact on American society and culture.

They have developed unique identities and cultural traditions in American society, including aspects such as **, art, literature, and social movements.

And black Africans refer to black friends from the African continent. Africa is a multi-ethnic and multicultural continent with a rich and diverse ethnic and cultural traditions. The identity and cultural background of black Africans varies according to the individual and ethnicity.

The culture of black Africans includes aspects such as language, religion, clothing, food, and art, and each ethnic group has its own unique traditions and customs.

Although Black Americans and Black Africans have different identities and cultural backgrounds, there are some commonalities between them. For example, they all face challenges of racial discrimination and unequal treatment, and they all strive for equal rights and social justice. In addition, there is also a history of cultural exchange and mutual influence between black Americans and black Africans, such as the influence of black Americans on Africa, and the influence of African culture on black American culture.

In conclusion, Black Americans and Black Africans are two different concepts that refer to Black people in the United States and the African continent, respectively. They have different identities and cultures, but they also have something in common, and there is a history of cultural exchange and mutual influence between them. <>
