Homo Sapiens

Around 13.5 billion years ago, energy, time, matter and space
had come to be known as the phenomenon of the Big Bang.
The theory of the fundamental features of the universe is
referred to as physics. Around 30,000 years when these
features had appeared, energy along with matter had started
the coalescing into various complex structures referred to as the
atoms. These then combined themselves into bigger molecules.
The theory of atoms along with molecules as well as its
interaction is referred to as the chemistry. Some 3.8 billion
years before, on some planet known as the Earth, several
molecules had combined to result in some large and
well-defined structures known as the organisms. The theory of
the organisms is referred to as biology.
Around 70,000 years before, the organisms which belonged to
the group homo sapiens had started forming even larger and
elaborative structures known as the cultures. The development
of these cultures is known as history.
The humans were present long before the time of history.
Various animals like the homo sapiens of the modern times
had appeared as early as around 2.5 million years before.
However, for several generations, these organisms were not
able to stand out from the various other organisms. The
biologists have classified the organisms into specific species. The
animals could belong to same species when they would have
similar characteristics or would mate with their own species.
The homo sapiens have been kept hidden as quite a secret
with respect to their exact origin and evolution. The homo
sapiens are believed to have first evolved in the provinces of
Eastern Africa some 2.5 million years before from the earlier
genus known as the Australopithecus which implies "Southern
Apes". Here is the detailed theory about the possible origin and
evolution of the Homo Sapiens on the Earth.
