(4) King C.C., (1985), A Model for Transposon-Mediated Eucaryote Regulatory Evolution J. Theor. Biol. 114 447. This paper presents a compact model of the role of transposable elements in eucaryote evolution which, although forward looking, is consistent with both experimental results and theories of gene regulation. The model postulates that a principal factor in the emergence of the eucaryotes was the development of a symbiotic relationship between reverse transcribing transposable elements and RNA based gene regulation, which we will call structural symbiosis. Thus, although transposable elements follow their own evolutionary protocol, structural homologies between "cellular" and "viral" genomes result in selective mutagenesis, a situation where transposon mutations are permitted because they can result in phenotypic mutations of the regulatory process with reduced probability of deleterious mutation of structural genes. The incorporation of this scheme into the life cycle of higher organisms results in two forms of integral evolution. Exogenous, in which differing species in an ecosystem share genetic information through viral transfer, and endogenous in which somatically induced regulatory mutations can be mapped back into the germ line.
