EVOLUTION OF THE BIO –DIVERSITY
The inorganic air moluecules converted into organic molecules in the per atmosphere cause of electric discharges and solar radiation. These substances dissolved in water and the first living forms originated.
Scientists believe that the pre ocean was a Primodial Soup and it originated by organic molecules.
This Primodial Soup contained Amino acids,nitrogenous bases, simple suger and nucleic acids.These molecules were unitedly cover by a layer of lipids. These structures evaluated in to pre cells.These cells contained the characteristics of living organisms such as growth self replication, This can be known as the origin of life. The organisms who formed for the first time on the earth are called as anaerobic heterotrophic prokaryotics.
According to this bio chemical evolution of the bio diversity, life originated before about 3.5 billions of years ago,on earth. In another hand who can discard the hypothesis that the life in our earth is just another laboratory for some group of well developed creatures out side of our Milky way.
