Not to discourage any new answers, but here is a profound answer by /u/400-rabbits to the question "Was there communication between Andean civilizations and Mesoamerican ones?".

TL;DR (pretty much): There almost certainly was no direct contact between those civilizations, but there were extensive trade networks through which goods (and ultimately, ideas) were exchanged.
