WebThe Fisherian mechanism can be given a concrete form by a genetic model based on … WebIn normal sexual reproduction, a gene that is "fair" has 0.5 + 0.5p chance of being passed on to the next generation (where p is the proportion of the population that has the gene). This kind of reproduction does not alter the frequency of the gene in the population. I think that a Fisherian runaway occurs when a gene (or genes) cheats the system. WebHere is the take-home message of our paper: hearing and sound production organs co-evolved via a Fisherian mechanism in Ensifera (katydids, crickets, and allies), but in Caelifera (grasshoppers), hearing evolved first probably in the context of flight modulation, and later co-opted for acoustic signalling when some groups evolved stridulatory ... pottery classes salt spring island
