2. 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
3. The answer are in the mitochondria
Mitochondria are minute structures described as the
“powerhouse of the cell”
4. 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.
6. 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
7. According to some theories, all female
mitochondria are as if they were interlaced
in a large umbilical cord & lead to Africa
8. Genetics theory postulates that Africa
was the cradle of Humanity
150 thousand years ago
in Kenya, Tanzania, Ethiopia
the first human beings went forward
9. 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 daughters
who had daughters
who had daughters
who had daughters…
who survived without interruption
until today.
10. About 70 thousand years ago
a 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.
11. Mitochondria help us track
the route that the first humans took
out of Africa to the rest of the world.
12. ¡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.)
16. 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.
17. 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
18. Scientifically speaking
a white is a
discolored negro
The difference between
“human races” consist in
a little more or
a little less melanin
19. 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.

20. Skin color
hair
curly or straight
noses
short or long
eyes
elongated or round
are adaptations
of the human body
to the different
environments
in which our ancestors
have lived.
THERE AREN´T DIFFERENT RACES
JUST DIFFERENT CLIMATES
22. 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!
