Hello Charles, I skimmed this article. Mesoamericans did use the wheel. That is accepted scientific knowledge now. The use of a wheel on a cart pulled by animals was not done in Mesoamerica because the largest animals available to pull such cart were llamas and alpacas — animals which didn’t live in the Mayan jungle.
This took 8 minutes of my time 8 minutes more than you or the old dude deserve.
