Karate comes from Muay Thai?

Fabulous article from Patrick McCarthy. 
“Ti’gwa [手小] was Okinawa’s plebeian form of percussive impact—–aka “Te,” “Ti,” “Di” [手 meaning hand/s] or Okinawa-te and Uchinadi. It was an art that depended principally upon the use of clenched fists to strike an opponent [in contrast to the open hand method preferred by Chinese arts, according to both Kyan Chotoku & Miyagi Chojun] although the head, feet, shins, elbows and knees were also favoured…Satisfied that I had successfully located the original sources from which came Tegumi (wrestling), Torite (qinna) and Kata, my efforts to trace the origins of Ti’gwa proved a bit more challenging. Exhausting my search of Chinese, Korean and Japanese sources, and considering the possibility the plebeian art may have evolved indigenously, I …was pleasantly surprised to learn that for more than a thousand years both China and India had influenced the development of local fighting arts in SE Asia. Henceforth I widened the scope of my study. In spite of the many remarkable fighting traditions I found in Indonesia, Malaysia and the Philippines, etc., none seemed to resemble the simplicity of Ti’gwa. The only other culture in which I could locate a tradition of similar qualities, within reasonable geographical proximity and contemporary historical timeframes, was the old Kingdom of Siam and its ancient art of boxing, Muay Boran. https://irkrs.blogspot.com/2013/04/siamese-boxing-original-source-of.html?m=1&fbclid=IwAR2NOqPKEs2rGCVVLUUL7CdpwQWNhNuMM8qKE-dCEaK39dwOHX2YpHj7OeI
