Um, over the decades, has there been enough research into those potential environmental factors?

It's a great question.

There has been some research in more recent years on environmental factors.

And by environment, I really mean anything outside of our genes.

And to date, the science really points most strongly to, um, several factors we've learned are environments, including preterm birth, so individuals, uh, that are preemies or have a higher likelihood of autism.

Uh, pregnancies where moms experience pregnancy conditions have also been associated with risk of autism in their offspring.

And there have been some studies on chemical toxicants, things like the air we breathe and air quality, and trying to understand whether that impacts autism.

Do you know anyone in your field that thinks that is a realistic timeline?
