How many human races are there on this Planet Earth? and what are their names?

Hello!

Researchers who have studied subjects from almost all regions of the world have realized that the DNA differences between two random individuals were approximately 0.5%. In addition, 86 to 90% of these were differences within the same racial group. Thus, only 14% or less of 0.5% of variation were observed between groups.

Humans are genetically homogeneous, that is to say basically the same.

The relatively few genetic differences between humans may still be important from a medical point of view, because a genetic factor seems to be factored into certain diseases.

A race in the sense discussed here, is an ethnic group which differs from the others by a group of inherited physical characteristics. However, the fact that men and women of different races can marry them and beget children is proof that they belong to the same "kind" and they are all members of the human family. Therefore, each race offers an overview of all possible variations within the human race.

All men living today belong to one species, Homo sapiens, and are derived from a common stock. Biological differences observed from one individual to another can be explained by differences in order hereditary constitution and the influence of environment on the genetic potential. In most cases, these differences are due to the interaction of these two groups of factors. The differences between individuals of the same race or the same population are often more marked than the average differences between races or distinct populations.

A breed is a group of genes isolated part where the human race eventually divide during and after its original geographic dispersion. Basically, a different breed was formed on each of the five major continents of the planet. The man has changed genetically during this phase of history, and it is possible to measure and study the results of this variation through the present remains of ancient geographical races. The change appears to be proportional to the degree of isolation. At the time of the formation of races on the continents, when, worldwide, thousands of tribes were confined in groups of genes isolated from others, differences in penetrance [or frequency with which a gene is manifested] that we see now appeared. It is ironic that each group of men appear outwardly different, whereas under these differences there is a resemblance fondamentale.Tôt in human history, when individuals were isolated from others and married them, a number Hereditary widened further distinctive character in their offspring.

Have a nice day!

Technically, any Biologist will tell you there is only one: Homo sapiens.

Among populations and nationalities, there are many variations of human skin colors, hair textures and colors, nose shapes, heights, and more characteristics; but there is no fixed DNA difference that does not average out if cross-bred. The DNA of two people of African origin can be as different as the DNA of a person of African origin and a person of Asian origin. The concept of race to distinguish groups with different appearances has social consequences, but virtually no genetically notable importance.

It should be noted that there is a colloquial usage of the word "race", which has roots in early exploration when various ethnicities came into contact, and does not parallel the scientific use. For example, the US Census gathers information of the "races" in America - meaning African American, Caucasian, Asian, etc. Yet it is stated clearly for the US Census by the Office of Management and Budget that its usage does not have foundations in "scientific or anthropological" definitions, and that "the racial and ethnic categories...should not be interpreted as being primarily biological or genetic in reference."

One, the human race.

There is only one human race on this planet. We are all part of it.

so which you're into New Age stuff, eh?for sure, you're able to be able to think of despite you like. yet once you desire to stay by the certainty you need to renounce your questioning and settle for the certainty. My theory is: we are able to save on with our lives even after 2012, simply by fact the prophecies interior the understand God (the Bible) had not been fulfilled yet and it rather is not likely they could be fulfilled in purely 4 years any further. for sure, human beings will forget approximately and could save on listening to another mambo jumbos after 2012. nicely, see you in 2012.

there are only one human race

The only race on Earth is Homo Sapien Sapien, (two sapien's is correct, one sapien is a Homo Sapien Sapien ancestor).
