Not doubting these points, but you should always cite peer-reviewed or otherwise verified sources. It makes all the difference between a fact and an opinion. This is especially true when contradicting a widely held belief. Without a verifiable source, these are just "interesting hypotheses".

I am glad you asked, here are the references.
1. Please read "Liber Abaci". It is right there in the prologue section. Hard to find a free copy of this link hence posting a link to tweet[1] with screenshot of the relevent page. You can also cross verify with Italian version on archive.org[2]
2. Same story repeat itself with Indian numbers and algorithms.[3][4]
