He argued that while it is true that at one time "there must have been a time when inorganic elements alone existed on our planet", "our ignorance is as profound on the origin of life as on the origin of force or matter", and denies that the theory of evolution requires that life continuously arises.

William Thompson, later Lord Kelvin, whose physical contributions included a denial that there had been enough time for natural selection to cause evolution later shown by the discovery of radioactivity to be wrongsaid in his presidential address to the British Association for the Advancement of Science in The bags of pulp were also returned to the primaries and the primaries were again sealed.

Possibly higher forms of life, such as infest the intestines, originate in this way. Moreover, he characterised the interaction between microbes and hosts as a "struggle for existence" a phrase, it must be remembered, invented by the Swiss botanist Alphonse de Candolle, and borrowed by Darwin.

Outside, on the covers of the closed flasks a few maggots eagerly sought some crevice of entry. As one biographer notes, "The observer had a choice between only two hypotheses: Nitrogen is not produced in the gut, but a component of environmental air.

The gut microbiome adapts to changing diets and conditions not only by shifting community membership but also by changing gene content via horizontal gene transfer. This syllogism fails, because evolution that is, common descent and transmutation of species occurs whether or not life arose by chance, law or design, but there is another more insidious mistake here.
