Studies on biological causes of ASD are notorious for failing to replicate and reaching contradictory conclusions. It is just as likely that you’d reach the opposite conclusion with children too
Because “ASD” isn’t really a thing, it is a whole bunch of different things with different causes and different symptoms semi-arbitrarily squished together under the one label, simply because those symptoms have some overlap. And every research sample is a random mixture of these different underlying conditions, and two different samples are unlikely to have the same mix, which is why studies of the same thing with different samples (even defined on the same criteria) frequently produce opposite conclusions. “Heterogeneity” is the technical term for this
