Origin And Evolution Of Life On Earth Pmf Ias Life appeared 500 million years after the formation of earth, i.e., almost four billion years back. some scientists believe that the life came from outerspace. the first non cellular forms of life could have originated 3 billion years back. they would have been giant molecules ( rna, protein, polysaccharides, etc.). This portion of blasted material then continued to orbit the earth and eventually formed into the present moon about 4.44 billion years ago. origin of earth. the earth broke off about 4.5 billion years ago with an explosion. over a long period of time, dust and gas gradually condensed to form solid rock.

The big bang theory. the big bang theory is the prevailing cosmological model for the universe’s birth. it states that 13.8 billion years ago, all of space was contained in a single point of very high density and high temperature state from which the universe has been expanding in all directions ever since. Origin and evolution of life: the origin and evolution of life is the last phase in the evolution of the earth. initially the earth or even the atmosphere of the earth was not conducive for the development of life. chemical origins of life: modern scientists refer to the origin of life as a chemical reaction, which first generated complex.

Origin of earth. the earth broke off about 4.5 billion years ago with an explosion. it was a burning hot white mass of gas and dust. over a long period of time, dust and gas gradually condensed to form solid rock. such condensation and shrinking made the earth heat up so much that the rock melted into a gluey liquid. after millions of years. Origin of life. the last phase in the evolution or origin of the earth relates to the origin and evolution of life. initially, the earth or even the atmosphere of the earth was not conducive to the development of life. scientists refer to the origin of life as a kind of chemical reaction, that first generated complex organic molecules and then.
