genetics doesn’t care about your feelings. If a human has the genetic issue (issue with cell division on a specific chromosome…i forget which one), they’ll typically have severe developmental challenges in childhood. And if unlucky, end up nonverbal.

I’m pretty sure most scientists would consider being able to communicate effectively with your own species, “normal”. Regardless of what animal you are. Just like it’s normal to have 5 fingers as a human. But some humans have more or less. That’s just…life.

No need to be unnecessarily sensationalist. I do agree that using the term “normal” should give someone pause. But warning bells? Depends on context…like everything in life. :)
