Hello, r/askhistorians!

I am a long time lurker of this sub and finally decided to post something. I hope you guys and gals can assist me in my current quest for understanding.

I do apologize if this is the wrong sub. If it is kindly point me in the right direction.

I have a stutter. I've been reading scientific research into this and it says that stuttering more than likely stemmed from a common ancestor, as a mutation in the genes.

I am here to inquire about who this common ancestor may be.

Historians, to your knowledge who is the first person who may have had this?

Thank you for your time and assistance. I do truly appreciate it.
