DIATOMS AND HGT. "Besides providing evidence for the ancient secondary endosymbiotic event at the origin of diatoms (and perhaps all chromalveolates), it was found that diatom genomes also contain a large number of genes (587 in P. tricornutum) proposed to be derived from bacteria by horizontal gene transfer." (HGT = Horizontal Gene Transfer). http://jxb.oxfordjournals.org/content/early/2012/01/20/jxb.err441.full View in LinkedIn

"HIGH MUTATION RATES of viruses combined with short generation times and pressures of natural selection allow viruses to quickly adapt to new environments. Add in vigorous horizontal gene transfer between viruses and other species, the genetic options multiply very fast." https://lnkd.in/e_-Sepw View in LinkedIn

SUPER-ORGANISM. "Mathematical models predict that viral quasispecies are not simply a collection of diverse mutants but a group of interactive variants, which together contribute to the characteristics of the population. According to this view, viral populations, rather than individual variants, are the target of evolutionary selection." https://lnkd.in/eb_myZ8 View in LinkedIn

BRUTE FORCE DIVERSITY. "Although a high mutation rate is dangerous for a virus because it results in nonviable individuals, it has been hypothesized that high mutation rates create a 'cloud' of potentially beneficial mutations at the population level, which afford the viral quasispecies a greater probability to evolve and adapt to new environments and challenges during infection." http://www.nature.com/nature/journal/v439/n7074/abs/nature04388.html View in LinkedIn
