Adding to taxonomic confusion, the conceptual nature of the coral species is a subject of debate, particularly regarding the permeability of reproductive boundaries between morphospecies, and the evolutionary significance and prevalence of interspecific hybridization (e.g. [9], [13] [20]).
Our results bring into question the prevalence, evolutionary conservation, and antiquity of internal or cryptic signals in proteins targeted to mitochondrial organelles.
Indeed, as genomic aberrations are inherited by daughter cells and their prevalences vary over genes, different prevalences (roughly, evolutionary selection frequencies) of DNA copy number aberrations suggest different fitness contributions.
While the mechanisms of EP are currently under debate, little is known about the prevalence and evolutionary history of EP in non-human animals; that is, which species are capable of EP and why [1]?
We believe that, in this post-genomic era, when protein structure data increase rapidly, it is very possible that plenty of information can be extracted to reveal the natural prevalence and evolutionary mechanism of DS as well as to accelerate the medical and bioengineering applications of DS.
This raises the question as to which evolutionary forces favor its prevalence.
Results from this alternative statistical model confirmed the high prevalence of evolutionary motif modification (supplementary material S4, Supplementary Material online).
For the 791 792 and 902 903 pairs of acidic residues there is a clear evolutionary trend of their prevalence within chordates.
Despite decades of study on this topic, no comprehensive explanation has been accepted that explains the evolutionary forces underlying its prevalence and persistence in nature.
In contrast to previous functional studies, evolutionary analyses comparing the prevalence of introns in essential and nonessential genes suggest that introns in nonribosomal protein genes are functionally important and tend to be actively maintained in natural populations of S. cerevisiae.
