Evolution of mutualism through spatial effect
WebOct 16, 2013 · Viewing mutualistic interactions through the lens of the maintenance of genetic variation, a classic framework shared by all of evolutionary biology, can (1) bridge the divide between the largely disconnected fields of coevolutionary genetics and mutualism evolution; and (2) provide a more predictive understanding of how … WebNov 20, 2012 · Most relevant for the gut microbiota is the issue of having multiple genetically different individuals on one side of the mutualism (microbes) involved in a single interaction with the other (host) [19], [20], [22]. On the side with multiple genotypes, this can lead to the loss of helpful mutualistic genotypes, whenever non-helpful genotypes ...
