The concept of human race



HUMAN RACE


Race is a classification system used to categorize humans into large and distinct populations or groups by heritable phenotypic characteristics, geographic ancestry, culture, history, language, physical appearance, ethnicity, and social status.  Now days we use the term taxonomy to look for genetic differences among the population.Some scientist use the term race or taxonomy because they think there is  a difference between all humans while there are some scientists that think that all humans belong to the same species, Homo sapiens. Social conceptions and groupings of races vary over time, involving the taxonomies that define essential types of individual. Scientists consider biological essentialism obsolete, and generally discourage racial explanations for collective differentiation in both physical and behavioral traits. There are many genes but most of people contain the same from others, the hair color, there physical similarities. As sciences says we all come from the same place, the same ancestors, at list all humans most have 1 gene in common with the rest humans..A human race is a group of people ( more than 1 thounsand) that share more than 59% of genes. There are many groups of humans that share genes like African people share the gene for the black skin, is an adaptation but the body takes it like a gene for that future generations of kids don’t have to go throw the process of adaptation, they ar eborn with that gene.  Think it or not you share more than 25% of your genes with everybody around the world because we all come from the same place, well that’s long time ago, but humans get more genes and they constantly are change them for adapt to their daily places they are.

Below here you will see the types of classification for humans. The one you may hear the most is Homo sapiens.

Eukarya 
Animalia
Chordata
Mammalia
Primates
Hominidae
Homo
Sapien (sapiens)
Sorry if you're confused, I'm sure you've heard of the term Homo Sapien, instead of calling us Homo Sapiens, our current name is Homo Sapien Sapien.
Eukarya - Cells with a nucleus
Animalia - Not an Autotroph (can't produce it's own food) Actually it is because we are multi-cellular, mobile and internally digest our food, and the term is heterotroph but some bacteria are also heterotrophic but are not animals.
Chordata - Has a backbone
Mammalia - Has hair, produces live young, feeds young milk.
Primates - Opposable thumb
Hominidae - Walks upright
Homo - The same, alike
Sapien - Wise



  
 



Between this four girls, is there any genetic difference?  There are physical, a normal person is able to find around 15 physical and metal differences, but how many can we find genetically.

Now day the society creates its own classification of human race. Humans have evolved since the beginnings of their journey.  We have created ways to classify our self.  Some people think because you’re from another country you will be another race from them but maybe you could have more than 60% of your genetic  alike to the people from that country.  People especially classify by the person skin color. But can that concept be change, maybe. Some effort you can change it.
