“Our knowledge of the origin of life always is more tentative than our knowledge of the subsequent evolution of life’s diversity”, why would that be so? What is our understanding of the origin of life and the origin species? Be clear.
Darwin wrote about the origin and evolution of species on earth on bill "on the origin of species'Darwin's theory has two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection. Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.
Darwin is considered the father of evolution.
The similarities known present-day species indicate that they have diverged through the process of evolution from a common ancestorThe 1952 Miller–Urey experiment and similar research demonstrated that most amino acids, the chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. Scientists have proposed manyexternal sources of energy that may have triggered these reactions, including lightning and radiation. Other approaches focus on understanding how catalysis in chemical systems on the early Earth might have provided the precursor molecules necessary for self-replication.Researchers generally think that current life descends from an RNA world, although other self-replicating molecules may have preceded RNA.
As a result of supernatural event there occured the first origin of life—that is, one irretrievably beyond the descriptive powers of physics, chemistry, and other science.
Life, particularly simple forms, spontaneously and readily arises from nonliving matter in short periods of time, today as in the past.
Life is coeternal with matter and has no beginning; life arrived on Earth at the time of Earth’s origin or shortly thereafter.
Life arose on the early Earth by a series of progressive chemical reactions. Such reactions may maybe improbable chemical reactions.
