Homo Sapiens

Around 13.5 billion years ago, energy, time, matter and spacehad come to be known as the phenomenon of the Big Bang. The theory of the fundamental features of the universe isreferred to as physics. Around 30, 000 years when thesefeatures had appeared, energy along with matter had startedthe coalescing into various complex structures referred to as theatoms. These then combined themselves into bigger molecules.
The theory of atoms along with molecules as well as itsinteraction is referred to as the chemistry. Some 3.8 billionyears before, on some planet known as the Earth, severalmolecules had combined to result in some large andwell-defined structures known as the organisms. The theory ofthe organisms is referred to as biology. Around 70, 000 years before, the organisms which belonged tothe group homo sapiens had started forming even larger andelaborative structures known as the cultures.
The developmentof 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 timeshad appeared as early as around 2.5 million years before. However, for several generations, these organisms were notable to stand out from the various other organisms. Thebiologists have classified the organisms into specific species.
Theanimals could belong to same species when they would havesimilar characteristics or would mate with their own species. The homo sapiens have been kept hidden as quite a secretwith respect to their exact origin and evolution. The homosapiens are believed to have first evolved in the provinces ofEastern Africa some 2.5 million years before from the earliergenus known as the Australopithecus which implies "SouthernApes".
Here is the detailed theory about the possible origin andevolution of the Homo Sapiens on the Earth.
