Editing Primordial soup (section)

==The Darwinian dynamic==

The [[evolution]] of living systems by [[natural selection]] that presumably emerged in the primordial soup, and certain nonliving physical order-generating systems, were proposed to obey a common fundamental principle that was termed the [[Charles Darwin|Darwinian]] dynamic.<ref name = Bernstein1983>Bernstein, Harris; Byerly, Henry C.; Hopf, Frederick A.; et al. (June 1983). "The Darwinian Dynamic". The Quarterly Review of Biology. 58 (2): 185–207. doi:10.1086/413216. JSTOR 2828805. S2CID 83956410.</ref>  The basic conditions necessary for natural selection to operate as conceived by Darwin are variation of type, [[heritability]] and competition for limited resources.   These conditions can apply to short replicating [[RNA]] molecules that were presumably present in the primordial soup, and such RNA molecules have been proposed to have preceded the emergence of more complex life (see [[RNA world]]).<ref>{{cite journal |vauthors=Cech TR |title=The RNA worlds in context |journal=Cold Spring Harb Perspect Biol |volume=4 |issue=7 |pages=a006742 |date=July 2012 |pmid=21441585 |pmc=3385955 |doi=10.1101/cshperspect.a006742 |url=}}</ref>  The basic processes of natural selection applicable to short replicating RNA molecules were shown to have the same form and content as equations that govern the emergence of macroscopic order in nonliving systems maintained far from thermodynamic equilibrium.<ref name = Bernstein1983/>  However, currently, the extent to which Darwinian principles apply to the presumed [[Prebiotic (chemistry)|prebiotic]] and protocellular phases of life, as well as to non-biological systems, remains an unresolved issue in efforts to understand the [[abiogenesis|emergence of life]].<ref>Schoenmakers, L.L.J.; Reydon, T.A.C.; Kirschning, A.
