Morphic resonance would provide an explanation for such a rapid evolutionary process (aversion on non aversion to Cattle Grids). The main alternative would be a neoDarwinian speculation of doubtful plausibility. Assuming that mutant genes for avoiding cattle grids arose by chance, natural selection might have favoured them because animals lacking these genes would tend to injure themselves by trying to cross grids; and even if they did not die of broken legs, breeders would tend not to use them as parents, choosing instead uninjured, grid-avoiding cows and bulls. But, at least at present, there is no empirical evidence for the existence of mutant genes for grid-avoiding; nor that cattle grids have imposed a significant selection pressure.
