SO ENDS two weekends on the parasite-host co-evolution. If evolution is the result of a broad and changing normal distribution curve driven by mutation and other factors, with selection at its edges for the best fit, then it gives credence to the axiom that a million monkeys with typewriters and Aeons of time could end up with a Shakespearean play.

RNA ALTERNATIVE VIEW. "We propose the alternative concept of qualitative RNA sociology that underlies the communicative competences of consortia of RNA stem-loop structures in constituting life." https://lnkd.in/eUYvi8e View in LinkedIn

FUNCTIONALITY. "There is no genetic program. The program is the functionality." https://www.dpag.ox.ac.uk/team/denis-noble View in LinkedIn

PLAN OR PROCESS? Enrico Coen: "Organisms are not simply manufactured according to a set of instructions. There is no easy way to separate instructions from the process of carrying them out, to distinguish plan from execution." (Professor Nobel in his book, the Music of Life). https://www.dpag.ox.ac.uk/team/denis-noble View in LinkedIn

VIRAL REMAINS DRIVE EVOLUTION. "Mobile elements within genomes have driven genome evolution in diverse ways. Particularly in plants and mammals, retrotransposons have accumulated to constitute a large fraction of the genome and have shaped both genes and the entire genome." https://lnkd.in/eiBC2Fd View in LinkedIn

MASSIVE EXPANSIONS. "Although the host can often control their numbers, massive expansions of retrotransposons have been tolerated during evolution." http://science.sciencemag.org/content/303/5664/1626 View in LinkedIn

SUCCESS STRATEGIES. "In nature, certain genes ‘drive’ themselves through populations by increasing the odds that they will be inherited." Five examples of these success strategies follow. https://lnkd.in/ewXxsGD View in LinkedIn

SUCCESS STRATEGY #1: "endonuclease genes that copy themselves into chromosomes lacking them." https://lnkd.in/ewXxsGD View in LinkedIn

SUCCESS STRATEGY #2: "segregation distorters that destroy competing chromosomes during meiosis." https://lnkd.in/ewXxsGD View in LinkedIn

SUCCESS STRATEGY #3: "transposons that insert copies of themselves elsewhere in the genome." https://lnkd.in/ewXxsGD View in LinkedIn
