FP An alternative approach to medical genetics based on m ern evolutionary biology Part mutation and symbiogenesis Journal of the Royal Society of MedicineRyan FP An alternative approach to medical genetics based on modern evolutionary biology Part retroviral symbiosis in embry ogy and normal physiology Journal of the Royal Society of MedicineR yan FP An alternative approach to medical genetics based on m ern evolution The starling and scary role played by viruses in biological evolutionA major thesis of this amazing book is that plants and animals including most significantly humans co evolve with viruses The term virolution presumably coined by Dr Ryan who is both a physician and an evolutionary biologist comes from the words virus and evolution but also suggesting the word revolution The idea is that instead of being merely agents of pathology viruses can also work together with their host to help it survive Ryan gives the example of grey suirrels imported from America invading the territory of red suirrels in Britain He writesAt first naturalists assumed that the grey suirrel was winning the survival battle because it was larger and aggressive than the native counterpart but now we know that the grey suirrel is carrying a suirrel pox virus that causes no disease symptoms in its symbiotic partner but appears to be lethal to the red suirrel p 96In other words what we have here is war by an organism's own viral pathogens Survival of the fittest may include carrying around lethal viruses that can wipe out your ecological competition Ryan notes We believe that HIV 1 the main virus of AIDS was transferred to people from a specific group of chimpanzees We also know that in chimpanzees HIV 1 grows freely and reproduces in their internal organs and tissues but it causes no evidence of disease p 86So what apparently happened is some bush meat eaters shot some chimps ate andor sold the meat and humans got the virus Revenge of the dead chimp Well perhaps But look at it this way Imagine humans in prehistory or even humans a few centuries ago in the Congo jungle looking to take over some chimp territory After some close contact the virus jumps from the chimps to humans and the humans die Survival of the fittestRyan refers to this as an example of aggressive symbiosis and this is how it works in general two similar species occupying similar ecological niches come into contact Which is to prevail One carries a virus like a loaded gun in its tissues The virus jumps to the other species and typically is extraordinarily virulent and kills them Or perhaps there is a dueling of viruses one from each species At some point the only survivors are those with immunity to the virusesRyan makes a further point with this example uoting Max Essex on the deliberate use of a myxomatosis virus to kill rabbits in Australia Thevirus killedsome 998% of the rabbits But then two things happened Number one within four years the resistant minority grew so you had a different population of disease resistant rabbits And number two the myxomatosis virus that remained as a persistent infection in the rabbits was less virulent so I think there is crystal clear evidence that both the host and the virus attenuated themselves for optimal survival in that situation Further and this brings us back to the previous point any new rabbits brought in would be at a disadvantage because they would have no immunity to the virus and the surviving rabbits would pp 87 88In other words looked at from an evolutionary perspective host and virus worked together in a mutualistic symbiosis In my mind this raises the uestion what really did happen to the Neanderthal We do know what happened to the natives of the Americas when they came into contact with the smallpox virus carried by the Europeans Could a virus from homo sapiens have wiped out the Neanderthal or at least helped humans become the sole hominid survivorsIn the largest sense this idea of host and virus working together would seem to be powerful than any kind of sharp tooth and massive claw in the struggle for survival The old idea of survival of the fittest must now be seen in a different light I have said for many years that everything works toward an ecology and everything works toward a symbiosis meaning that in a typical environment if one species is able to work together with another they may enjoy an advantage over rivals Conseuently those species that are able to form symbiotic relationships are the ones likely to survive What this means for evolutionary theory as Dr Ryan has pointed out is that symbiosis is a much important part of evolutionary biology than has previously been thought My guess is that the revolution begun by Lynn Margulis who first saw the eukaryotic cell as a mutualistic development from parasitic relationships will be accelerated by the work of Ryan and others to the point where the prevailing view from evolutionists will be that it is cooperation rather than competition that most characterizes fitnessAnd that is what makes this book so important It signals a great shift in our understanding of how evolution worksBut that is not all Ryan shows that the so called junk DNA in genomes is anything but Much of it is viral endogenous retroviruses and it is there as evidence that humans and pre humans went through many periods of aggressive symbiosis including the horrid plague stage We now see that plagues from an evolutionary perspective are common and part of how the evolutionary process formed us Further Ryan writes about how viral genes can help with the development of the embryo in the womb In other words viral DNA in part directs the protein building that makes for human beings and indeed for many forms of lifeIn the latter parts of the book Ryan explores the role of viruses in autoimmune diseases and cancer He also considers the role of hybridization in evolutionary change and that of epigenetics Particularly interesting is the work of Eva Jablonka and Marion J Lamb that suggests that new species might arise through the inheritance of acuired epigenetic changes causing Ryan to remark they were resurrecting the long discredited spectre of Lamarckian evolution p 312The book is dense difficult and perhaps revolutionary in scope Dennis Littrell author of “Understanding Evolution and Ourselves”
