I recently came across a theory that older parents are more likely to pass on autism to their children. But can we give this theory to ALL of the autistic children? My own father was twenty-five at the time of my conception. (My mother was twenty-eight.) I think this theory cannot hold the water in every single case. Perhaps there are younger parents who pass on autism to their children without any so-called “inferior” genes. Regular genetics, whether by chance or design, is a much stronger theory, and autism existed long before it was discovered and named.
If you don’t believe autism existed before its naming, consider the behavior of the “fairy changeling.” In many changeling legends, there exists behavior similar to autistic meltdowns and stimming. Wikipedia has several examples of this behavior listed in the various cultures of changelings. But I digress.
Since there is evidence of autism and other conditions in fairy changeling folklore, I propose that autism existed long before its naming, and that its existence is purely due to genetics – not genetic mutation caused by older and therefore “inferior material.”
