We propose that transposable elements can be seen as both accelerators of the evolutionary process and mediators of the evolution of evolvability.
Segmental duplications have been recognized as important mediators of both gene and genome evolution [ 1- 9].
The identification of syndecan-encoding sequences in multiple species of Cnidaria provides a strong indication that syndecans, like integrins, have participated as mediators of extracellular interactions throughout animal evolution.
Androgens, for example, mediate proliferation, apoptosis, oxidative stress, and perhaps inflammation in the prostate, and are therefore likely primary mediators of selective pressure in the evolution of prostate cancer.
The exact role of Th1 and Th17 mediators in the evolution of nvH1N1 mild and severe disease merits further investigation as to the detrimental or beneficial role these cytokines play in severe illness.
The ability of AM fungi, EIPF and some species of ectomycorrhizal fungi, three phylogenetically disparate fungal groups, to act as mediators of plant nutrient transfer suggests convergent evolution as root colonizers and conduits of nutrient transfer.
The results from the microarray-based comparison provide further evidence concerning the intense transpositional activity of several horizontally transferred elements and reinforce previous studies regarding the importance of lateral gene transfer as a major mediator in the evolution of this important group of phytopathogens.
Results from microarray-based comparisons provide further evidence concerning activity of horizontally transferred elements, reinforcing their importance as major mediators in the evolution of Xf.
This is proof of evolution.
Parody of evolution of scat vocals.
