Understanding the formation of biogenic molecules in abiotic conditions is a prerequisite in the origin-of-life studies.
Nursall, J. R. Oxygen as a prerequisite to the origin of the metazoa.
For example, there are multiple families of LTR retrotransposons in mammals, but they probably didn't proliferate fast enough to sufficiently affect the divergence of different subpopulations, which is a prerequisite for the origin of new species with large families.
Moreover, the unexpected evolutionary dynamics of the mtDNA of tunicates suggests caution in the usage of this molecule to reconstruct the phylogeny of Chordata, which is in turn a prerequisite to understand the origin of Vertebrata [ 32].
Cases where either parent has an expression of 0 were dropped from this analysis because parental expression is a prerequisite for tracing the origin of hybrid alleles.
The reason is bioenergetic and boils down to mitochondria, which are the prerequisite to the origin of cell complexity -- hence phagocytosis -- in eukaryotes [ 147], not vice versa.
That study deals with a prior stage in the origin of life, the one leading to a replicase which – we claim – is a prerequisite for the (proto- cellular stage.
But this kind of hustling is pretty much a prerequisite in Pa'nucci's line of work.
Although these facts are fundamental, and have inspired scenarios for the evolution and the expansion of the code [26] [28], evolutionary considerations may not, in essence, provide an answer to the origin of the code (since it is a prerequisite for biological evolution).
Locating the root of the tree of life is a prerequisite for understanding the origin and evolution of life.
An in-depth understanding of the origin of low lattice thermal conductivity κlat is considered to be the prerequisite for developing and designing high thermoelectric performance materials.
