Final answer:
The claim that Native Americans spoke over 375 languages is true but the agricultural revolution timeline is too specific; it unfolded over thousands of years, not just 2500 years ago.
Step-by-step explanation:
The statement that Native Americans spoke over 375 languages and that the Native American agricultural revolution began 2500 years ago in Mexico is partially inaccurate. While it is true that Native Americans spoke a high number of languages, the agricultural revolution did not begin exactly 2500 years ago; the transition to agriculture took place over thousands of years, with major crops like corn, potatoes, and cassava being developed. Linguists do believe that Mesoamericans spoke more than 125 different languages, and the agricultural revolution had a profound impact on society and culture in the Americas. The cultivation of crops, such as corn, allowed for more permanent settlements which eventually gave rise to great civilizations like the Maya, Aztec, and Inca.
