Yes that's right. Autism is cannibals. Don't worry, like all animals that consume conspecifics, autistic people will not attempt to eat conspecifics if fed (and in some cases restrained).
This explains why there are more combinations of genetic expression found in autism than any other genetic disorder. It is because it relates to something so fundamental as 'Which way does which food travel?', this is applicable to any higher animal and certainly any mammal.
Whenever a population of animals experiences cannibalism, that population adapts to attempt to recognise predation in it's midst. Any obvious predators are removed but still nature keeps churning out new cannibals! It's not the baby's fault, it's the fault of the human race for being so good at producing food yet paradoxically easy to catch and eat, superficially speaking.
They say that when you've met one person with autism you've met one person with autism. Nature and evolution will try absolutely anything to get at the best meat (which she has been making for herself all this time).
Cannabis is the cure for Cannibals. That's the hypotheses, will it stand the test of time? Only the elimination of all other possible aetiologies for autism would leave the obvious, however unthinkable, as the strongest contender.
Those autistic mice by the way, what the researchers don't tell us is that half these autistic mice are eating the other mice when they don't feed them and put them in a cage together.
