How many races in the world?

Question please

I believe there is one

per continent

In school they talked about four races: white, yellow, black and red.

I don´t know how many

there are but one is

superior…¡white!

Let´s investigate how many races

there are

And if one is superior to the

others

The answer are in the mitochondria

Mitochondria are minute structures described as the “powerhouse of the cell”

Chromosomes (DNA) are inherited from the mother and father

But mitochondrial DNA is only

inherited from the mother

The egg cell contains relatively few mitochondria, but it is these mitochondria that survive and divide to populate the cells of the adult organism, a pattern

known as maternal inheritance.

From mother

To daughter

To granddaughter…

“Every drop of human blood contains a history book written in the language of our genes”

IF WE REWIND THE HUMAN HISTORY MOVIE

We could go back generation to generation, until our origins

And we would get to the primary womb, the mother

of all human beings that inhabit this world

According to some theories, all female mitochondria are as if they were interlaced in a large umbilical cord & lead to Africa

Genetics theory postulates that Africa was the cradle of Humanity

150 thousand years ago in Kenya, Tanzania, Ethiopia

the first human beings went forward

There lived that woman.From her descended the 7 billion

that inhabit this world.

She wasn´t the first or only mother.But only she had daughterswho had daughterswho had daughterswho had daughters…who survived without interruptionuntil today.

About 70 thousand years agoa small clan emigrated from Africa.Some traveled west and made it to Europe.Others took the east road.Crossed Asia, climbed up the Siberian steppe… and made it to America.

Mitochondria help us track the route that the first humans took out of Africa to the rest of the world.

¡Wait a minute!According to this theory, if Africa

is the cradle Humanity…

¿Does that mean that Eve was

black?

¡Exactly! (Except

that there are other theories, especially the Bible.)

¿And what… our ancestors were black?

¡Exactly! (According

to this theory.)

It´s better to say skin color.

Because there is only one race-

the human race

And then,¿Where do so many races come from?

¡That´s bull!¿Then why I´m I white?

Because your are missing

Melanin

I don´t

know

who she

is

Melanin is the pigment that gives color to the skin. In Africa, with so much sun, skin is dark for protection against ultraviolet rays that produce cancer.

When our ancestors traveled to cold climates

they began losing melanin in order to capture more of the sun´s rays that allowed them to produce vitamin D

Scientifically speaking a white is a

discolored negro

The difference between “human races” consist in a little more or a little less melanin

This doesn´t convince me

because in Canada and other cold

climate countries live people who are black and they don

´t discolor

The change in skin color does not happen in one generation, but across thousands of years.

Nature always works with patience.

THERE AREN´T DIFFERENT RACES JUST DIFFERENT CLIMATES

WE HAVE THE SAME BLOOD WE BELONG TO THE SAME FAMILY WE COME FROM THE SAME PLACE

FIN, i.e. there is only one race, the human race, whether we believe that it started black and turned white, or started white and turned black, and brown.

¡Pass it on!
