INTRON LOSS DOMINATION. "All in all, intron loss clearly dominated the evolution of eukaryotic genes, with episodes of substantial gain linked only with the emergence of some major groups, especially animals, in full agreement with the results of the evolutionary reconstruction for the eukaryotic domain repertoire." http://onlinelibrary.wiley.com/doi/10.1002/bies.201300037/full View in LinkedIn

"THE DISPOSABLE SOMA THEORY on the evolution of ageing states that longevity requires investments in somatic maintenance that reduce the resources available for reproduction. Experiments in Drosophila melanogaster indicate that trade-offs of this kind exist in non-human species. The findings show that human life histories involve a trade-off between longevity and reproduction." https://lnkd.in/dusZvgm View in LinkedIn

MASSIVE INTRON LOSS. "Remarkably, intron-rich ancestors were reconstructed even for those major groups of eukaryotes that currently consist entirely of intron-poor forms such as the alveolates that apparently evolved via differential, lineage-specific, extensive intron loss." http://onlinelibrary.wiley.com/doi/10.1002/bies.201300037/full View in LinkedIn

POPULATION SURVIVAL. Disposable soma theory. "That populations survive indefinitely while individuals grow old and die requires that young offspring be produced at the expense of old parents, and this has classically been explained in terms of an immortal germ line passing through a transient and disposable soma, or body." https://lnkd.in/d9ymnPc View in LinkedIn

THE INTRON FACTOR. "The reconstructions consistently indicate that ancestral eukaryotes including the LECA and the founders of each supergroup were intron-rich forms, with intron densities higher than those in the genes of most extant eukaryotes and probably only slightly lower than those in the modern organisms with the most complex gene structures, such as mammals." (LECA = last eukaryotic common ancestor). http://onlinelibrary.wiley.com/doi/10.1002/bies.201300037/full View in LinkedIn

LOGICAL HESITATION. "Now, one might argue that the longer the organism lives, the more offspring it can produce, and the more copies of its genes will be made. Hence, the genes of organisms that do not age, and thus live longer, would be naturally selected." http://pespmc1.vub.ac.be/evolage.html View in LinkedIn

GENE VEHICLE. "For a gene, the main criterion that must be fulfilled or maximized in order to be naturally selected, is that its vehicle (individual organism) should survive long enough to be able to produce (numerous) offspring." http://pespmc1.vub.ac.be/evolage.html View in LinkedIn

UNIT OF EVOLUTION? "Individuals are merely disposable vehicles for the replicating information contained in the genes. As long as the genes survive (that is, are replicated in offspring before the individual dies), the survival or death of the individual is not very important." http://pespmc1.vub.ac.be/evolage.html View in LinkedIn

SURVIVAL OF THE GENE. "A useful way to look at this problem is Dawkins's "Selfish Gene" picture of evolution, where the fundamental unit to be maintained by natural selection is not the individual, nor the group or the species, but the gene." https://lnkd.in/ecMXQ_u View in LinkedIn

DARK DRIVER OF EVOLUTION. "Evolution advances by means of death (as opposed to the survival of the "fit")? That's a dark spin on Darwinian theory that I didn't expect to come across." http://www.evolutionnews.org/2012/11/evolution_by_me066801.html View in LinkedIn
