 The species
that displaced the Neanderthals, Homo sapiens, is characterized by a more
slender appearance than all other homo species. They have thinner skeleton,
rounder skull, smaller faces with prominent chins. Their brain capacity averages
1350 cm. Homo sapiens first appeared in the fossil record, in what is now Ethiopia,
about 195,000 years ago.This early Homo sapiens made chipped hand axes and
other sophisticated stone tools.

 They appeared to have had the abilities to use
a range of resources and environments, and at some point they began migrating
out of Africa.


The world
population 200,000 years ago looks significantly different than it does today.
It was predominantly inhabited by a morphologically diverse genius of hominins, including
primitives human, Neanderthals, and modern humans. By 30,000 years ago,
nonetheless, only modern humans remained/existed. Some scientists propose that this modern humans
evolved from several dispersed populations of early homo species at the same
time in different areas of the world. 

According to the multiregional evolution
model, modern races of human arose in isolated population by destinate convergent
evolution. Most scientists hypothesis the global dominants of modern humans with
the Africa replacement model or, more commonly, the out-of Africa hypothesis. According
to which was first proposed by Christopher stringer and peter Andrews of the
British museum of natural history in 1988, modern humans evolved only once, in
Africa, and then migrated to all part of the world, eventually displacing all
other hominins.

The out-of Africa
hypothesis was supported by mitochondrial DNA analysis of the contemporary
humans in the early 1990s. mitochondrial DNA changes very little over time, and
human living today have nearly identical mitochondrial DNA. Researchers Allan Wilson
and Rebecca Cann of the University of California, Berkley, reasoned that the population
with the most variation should be the population that has had the longest time
to accumulate diversity .this was exactly what they found in the mitochondria
DNA of Africans. Because mitochondria DNA I inherited only from the mother, this
analysis suggested that hommosapiens emerged from Africa about 200,000 years
ago from a hypothetical “Mitochondrial eve”.
Later, work
by other scientist studying DNA sequence in the male while chromosomes yielded similar
results. While some scientist thinks that a little movement of only a few
hundred modern humans ultimately gave rise to the world current population,
other think that process occurs in phase, with some interbreeding among the
specie that woman displaced. 
The beginning
of the culture of man was first experienced as at 40,000 years ago. The first
evidence of the complex human culture appeared in Europe only about 40,000
years ago, shortly before the Neanderthals disappeared. However, the Neanderthals,
early modern human expressed themselves symbolically and artistically in
decorative artifacts and cave drawings.
They developed
highly sophisticated tools and weapons, including spears and bows engrossed with
series of arrows. 
According to research, they were the first to fish, the first
to tailor clothing, and the first to domesticate animals. This and other numerous
cultural expressions marked the age and full dominance/appearance of fully modern
humans, the subspecies Homo sapiens. Some
people around the globe/ universe label them Cro-Magnons. They proportionally present the beginning of historic
hunter –gather societies.
showed that humans continued their migration quest through out Europe and Asia. 
They probably reached Australia by boat and traveled to North America through
land bridges from Asia. From North America, they seemingly spread to south
America. They adapted to new challenges along the way, leaving behind a trail
of artifacts which current scientist, including me and you study.
In summary,
you have to comprehend without antagonism that, The genus Homo is thought to
have evolved from the genus Australopithecus. After series of research, without
much debate the first member of the genus Homo, which was H. habilis also

The most
important fact here is that about 30,000 years ago, the H. neaderthalensis went
extinct and H. sapiens moved into
those areas inhabited by H. neaderthalensis approximately the same time.
