Fig. 3 Factors that influence the population and evolutionary dynamics of TEs.

Our understanding of TE population and evolutionary dynamics is still incomplete. The different factors that affect TE population and evolutionary dynamics are interrelated, new factors have been identified in recent years, and future research is still likely to reveal existence of additional factors

The additional factors include natural selection for energy-dependent codon optimality, which links the claims from “Codon identity regulates mRNA stability and translation efficiency during the maternal-to-zygotic transition” to all biodiversity in jawed vertebrates via the physiology of pheromone-controlled reproduction in bacteria.

This paper explores the complex relationship between the plant evolutionist G. Ledyard Stebbins and the animal evolutionist Theodosius Dobzhansky. The manner in which the plant evolution was brought into line, synthesized, or rendered consistent with the understanding of animal evolution (and especially insect evolution) is explored, especially as it culminated with the publication of Stebbins’s 1950 book Variation and Evolution in Plants. The paper explores the multi-directional traffic of influence between Stebbins and Dobzhansky, but also their social and professional networks that linked plant evolutionists like Stebbins with Edgar Anderson, Carl Epling, and the ‘Carnegie team’ of Jens Clausen, David Keck, and William Hiesey with collaborators on the animal side like I. Michael Lerner, Sewall Wright and L.C. Dunn and other ‘architects’ of the synthesis like Ernst Mayr, Julian Huxley and George Gaylord Simpson. The compatibility in training, work styles, methodologies, goals, field sites, levels of analysis, and even choice of organismic systems is explored between Stebbins and Dobzhansky. Finally, the extent to which coevolution between plants and insects is reflected in the relationship is explored, as is the power dynamic in the relationship between two of the most visible figures associated with the evolutionary synthesis.

Only fools pretend to not know that the so-called ‘evolutionary synthesis’ is food energy-dependent pheromone-controlled ecological adaptation in the context of biophysically constrained viral latency.
