This is an impossible question to answer as mesoamericans still live. These are the native people who live in the region of Central America from central Mexico to the southern border of Costa Rica.
If you mean to refer to the group or tribe of mesoamericans and those who remained active the longest, it is still impossible to answer as people have lived in the region from about 11,000 BCE or before, and these broke up into the various tribes, which incorporated each other, merging and combining and remerging. Those with native ancestry from the mesoamerican region will be able to trace back to Aztecs, Incas, Olmec and others.
