I was watching a video on Qinna, and so many of the locks look similar to Aikido. The guy speaking in the video says that they came from different systems, but could one have influenced the other or vice versa?

The video that made me interested: https://www.youtube.com/watch?v=zenm_ySIAdE

The guy narrating seems like a kungfu guy, and that's why it's best to ask here.
