1. The Origins of Modern Man

2. Since time immemorial, man tries to explain its origin.
Initially and lack of scientific knowledge man pleaded
mythical and religious aspects to describe its genesis
through creationism.
Lamarck (século XIX) - evolutionary current
Darwin - theory of African origin
Recent scientific and technological advances in the areas
of Molecular and evolutionary biology and the field of
archeology, suggest that the phylogeny of modern man,
Homo sapiens, appeared in the African savannah.

3. Multiregional model - centered on a simultaneous
evolution in different parts of the globe, by the
action of natural selection, from a successive wave
of ancestors who left from Africa more than 1.5
million years;
Out of Africa model - explains the common origin
of humanity, through microevolution and only a
small population on the African savanna that existed
about 200 million years ago and subsequently
found to have spread and diversified into other
continents This model Out of Africa is the most
consensual in the scientific community due to
mainly genetic arguments.

4. The Ark of Noah, Black Eve, the hypothesis of
substitution, the single source model and recent
developments in Africa, are designations that some
authors use the model to define the evolution of
anatomically modern Man Out of Africa.

5.  The mitochondrial DNA is a wholly maternal transmission
mode, so do not recombine or mutates. Variance analysis of
the molecular composition of mitochondrial DNA mutations
and their neutral individuals suffered in
Africans, Asians, Europeans and ameríndeos determine a
supposed source of all modern human lineage;
 The Y chromosome, by their paternal inheritance, nor
recombines, with exceptions in some areas. The analysis of
non-recombinant part of the Y chromosome in the current
population, also demonstrates a recent origin African
common between 100 000 a 200 thousand years.

6. We identified five major population groups:
Negroid (African), White (European), Mongoloid
(Asian), American Indians (Native Americans)
and Australoids (Australians and Papuans).
Paleontological and genetic data suggest that
these groups are the result of a complex
history of human migration and their
recombination with archaic populations, in
combination with genetic factors and natural
selection, which came into action, since Homo
sapiens increased its population and expanded
from Africa.

7. Initially a group of humans moved to the Northwest Asia
through the Middle East and settled in Southeast Asia.
Another group went to India and then to Southeast
Asia, recombining them again. Part of the population went to
the Pacific and Australia, and the other party, recombined
again eliminating the traces in many African populations.
Europe received from the Paleolithic, several waves of
migration from the east. Already in the Neolithic farmers from
the Middle East, Northern Caucasus and the Black and
Caspian Seas and later from Greece, took its genetic material
to Europe, expanding to the Iberian Peninsula.

8. Genetic studies have had a major role on the
origins of modern man and his common
ancestry. Also provided, profound
evidence, that human "races" were biologically
insignificant and that their variation is due to
differences progressive factors from its
origin, through geographical isolation and the
rate of differentiation.

9. All modern humans share a recent
common ancestor and the differences
between people today are the result of the
last thousands of years of history. Like all
life on Earth has a common ancestor, also
the story of the evolution of the modern
human population shows a common
ancestor to all humanity today.
