Natural origin accidents

Clearly this means a complete rejection of the fundamental Darwinian principle of common descent. Also, he rejects mutation and natural selection as the mechanisms that produced species. Is this view also contrary to the universality of biochemistry, and in particular the monophyletic origin of life, to which most biochemists today would subscribe Probably yes but of course if one assumes an absolute determinism, then the laws of chemistry and physics would produce the same products at each different start. This goes against the notion of frozen accident and the unique origin of the genetic code. So, there was never a time on Earth with only one kind of species, and the development of species was parallel rather than sequential. Of course all these ideas are substantiated by arguments and data - for these, the reader should refer to the original sources. 

The scope of the ASI fits the definition of NATO Priority Research Topics as Environmental Security that can be defined as the relative public safety from environmental dangers caused by natural or human processes due to ignorance, accident, mismanagement or design and originating within or across national borders. From this standpoint, the objectives of Green Chemistry are indeed aimed to minimize the environmental concerns caused, inter alia, by many human activities. 

This proposal for the hrst association of membranes with reductive metabolism is consistent with their later use as containers that enhance reaction rates involving enzymes produced by side reactions from the core cycle. It is a natural sequence for the cellularization of primordial autotrophs, in contrast with heterotrophic origin stories where macromolecules are responsible for the hrst imprinting of heritable structure, and in which catalysts hrst become enclosed in membranes more or less by accident [84]. 

Secondary accidents refer to the accidents caused by natural irresistible factors, the rescue party s negligence or the wrong operation of the persons concerned on the basis of the original medical malpractice, coal mine accidents, and traffic accidents and so on. The secondary accidents mentioned in this paper refer to the accidents caused by improper rescue during the process of emergency rescue in coal mines. 

Finally, this work su ests that origin of life was not a one-time historical accident but a natural and, perhaps, potentially inevitable consequence of an interplay between the solar UV-light and the geochemical conditions that existed once on the ancient Earth.
