“…There is now independent support for punctuated equilibrium from studies of extant taxa (Cubo 2003;Pagel et al 2006;Mattila and Bokma 2008;Laurin et al 2012), from co-evolution (Toju and Sota 2009), and in extant and ancient genomes of Gossypium species due to intermittent TE activity (Palmer et al 2012). TE-Thrust provides an intragenomic explanation of punctuated equilibrium Greene 2009a,b, 2011), as has also been suggested by Zeh et al (2009), via epigenetic changes, and/or endogenization of retroviruses, in response to stress, and Parris (2009), via endogenization of retroviruses and environmental change.…”

In addition to the strong divergent evolution and significant and episodic evolutionary transitions and speciation we previously attributed to TE-Thrust, we have expanded the hypothesis to more fully account for the contribution of viruses to TE-Thrust and evolution. The concept of symbiosis and holobiontic genomes is acknowledged, with particular emphasis placed on the creativity potential of the union of retroviral genomes with vertebrate genomes. Further expansions of the TE-Thrust hypothesis are proposed regarding a fuller account of horizontal transfer of TEs, the life cycle of TEs, and also, in the case of a mammalian innovation, the contributions of retroviruses to the functions of the placenta. The possibility of drift by TE families within isolated demes or disjunct populations, is acknowledged, and in addition, we suggest the possibility of horizontal transposon transfer into such subpopulations. “Adaptive potential” and “evolutionary potential” are proposed as the extremes of a continuum of “intra-genomic potential” due to TE-Thrust. Specific data is given, indicating “adaptive potential” being realized with regard to insecticide resistance, and other insect adaptations. In this regard, there is agreement between TE-Thrust and the concept of adaptation by a change in allele frequencies. Evidence on the realization of “evolutionary potential” is also presented, which is compatible with the known differential survivals, and radiations of lineages. Collectively, these data further suggest the possibility, or likelihood, of punctuated episodes of speciation events and evolutionary transitions, coinciding with, and heavily underpinned by, intermittent bursts of TE activity.

“…The genetic program important in the formation of a multicellular organism would be located in the non-coding area, through fine processes of genetic regulation via proteins, retroviruses, transposable genetic elements, introns and ncRNAs. Recently, a model has been proposed based on a hypothetical “master development program” for multi-cellular organisms where the DNA sequences are protected by the heterochromatin and transcribed into “Control Keys” that consist of nuclear messenger RNAs that regulate high-level transcription factor genes [ 12 ].…”

Non Coding RNAs and Viruses in the Framework of the Phylogeny of the Genes, Epigenesis and Heredity

The origin of genes is one of the most enigmatic events in the origin of life. It has been suggested that noncoding (nc) RNA was probably a precursor in the formation of the first polypeptide, and also at the origin of the first manifestation of life and genes. ncRNAs are also becoming central for understanding gene expression and silencing. Indeed, before the discovery of ncRNAs, proteins were viewed as the major molecules in the regulation of gene expression and gene silencing; however, recent findings suggest that ncRNA also plays an important role in gene expression. Reverse transcription of RNA viruses and their integration into the genome of eukaryotes and also their relationship with the ncRNA suggest that their origin is basal in genome evolution, and also probably constitute the first mechanism of gene regulation. I am to review the different roles of ncRNAs in the framework of gene evolution, as well as the importance of ncRNAs and viruses in the epigenesis and in the non-Mendelian model of heredity and evolution.
