Are there any biological differences between the blacks in africa and the blacks in america?

Question

ive noticed a difference in the blacks from pure african descent, and the blacks that were brought over during the slave trade. some blacks i know look more african than other blacks. Is there any reason to this?

Answer 1

Yes, supposedly over 90 percent of American blacks have at least one white ancestor somewhere in their bloodline-- thats why many are so lightskinned compared to those in Africa.

Answer 2

The blacks from africa have less or no integration with whites, hispanics,  or any others who may have kept them as slaves.  EG: The british, french, germans,dutch or spanish

Answer 3

I'm sure there are. One thing I can think of is that African AMERICANS have logically had more opportunities to have children with other races (caucasian,asian,hispanic) and that chances the biology obviously. Also, the blacks that remained in Africa have had to evolve to deal with the diseases (malaria,HIV,etc) that Africa is rampant with and have had to keep the darker skin to deal with the heat there.

Answer 4

Africa is an ENTIRE HUGE continent!

That's like saying Mexicans seem different than Eskimos.

They are!  The point is, slaves came from certain areas mostly, like not Egyptians (also African).

Answer 5

Most of the ones brought over here were from the Eastern parts of Africa.  They come in all shapes, colors and sizes through out Africa.

Answer 6

There are differences because blacks in the United States and (the Caribbean!) have had interracial relations with other races more often than those in Africa. In some Caribbean islands (Trinidad) the population is a composite of countless racial combinations from Hispanic to Arabic. a lot like what the U.S. is experiencing now.

Answer 7

Sure, I have noticed the same kinds of difference between white americans and europeans.  

I can only conclude that white americans and black americans have a long history of intermarriage and that all the americans today are part of each.

Answer 8

all black people are african american.. even if they don't know it.. some people just don't trace that far back in familly trees...and in some point in time, they might've mixed with other races this may change the color tone of the offspring's skin.

Answer 9

Yes if they live in the North, they might get lighter over the generations.  Even the southern parts of America are far less hot and humid than most of Africa.

Other than that there are really no biological differences between "race".  We are less than 1% varied as humans and of that variation, 85% of variation occurs across racial lines.  And the genes that affect skin color aren't really connected to or related to any other genes.

Answer 10

"Biological"? No.

Just cultural. Invironmental.  Looks have nothing to do with biology.

We're all pretty much the same on the inside.

Answer 11

The black people in the Americas are not all descended from Africans, they often aren't 100% African, and they probably aren't 100% from one area in Africa.  They're just as much of mutts as your average European descended American.

There are other areas that aren't Africa where you can find people bearing many of the same characteristics as Africans.  Back in the day, we took slaves from there, too.  Blacks who came into this country also interbred with other ethnic groups, either through the general nastiness of slavery or by their own choice.  In fact, there used to be a whole list of terms for how much black blood a person had versus white blood and/or native blood.  Thankfully, we don't use this anymore.  And, of course, blacks from one part of Africa look as different from blacks from another part as a Russian looks from someone who's Irish.

You also asked about biological differences.  Well, there's probably as much in the case you mention as there is between me, a fifth or sixth generation European American mutt, and a random European; that is to say, not much.  Racial differences are mostly pretty shallow.  The various races aren't even far enough apart to count as different varieties, like you get with dogs or some kinds of trees or some kinds of birds.  We all of us have no problems whatsoever interbreeding, which is a major hallmark of genetic closeness, and anyone can adopt a child from anywhere else in the world and raise it to fit in perfectly in his or her new environment.  So while you'll get different "looks" or even different responses to disease, we're all basically the same.

Answer 12

People are just people.  No difference.

Answer 13

cross breeding, most blacks in America have some white ancestry.

as to the people who say it is evolving, no no way, evolution does not happen that fast.
