The enigma of life origination on Earth is an open question for biomedical scientists. Apart from derivative arguments from Darwin’s theory (gradual evolution), some other evolutionary hypotheses have been established—including the evolutionary step of genetic information duplication from prebiotic broths, outsider living-form landing, from volcanic eruption in deeper sea and cooperative biological origin hypothesis and so on. In this editorial article, we discuss the advantages and limitations of different types of life-origin hypotheses and proposed crucial steps in evolutionary progression of life origin on Earth. The major objective of this editorial is to elucidate the different characters of many existing hypotheses.
