The document analyzes the book 'The New Trinity: Blood-Fetishism, Blood-Catharsis, Blood-Donation,' discussing its impact and limitations in presenting the history of Mesoamerica from 2000 BCE to 1521 CE without integrating recent archaeological findings. It raises critical questions about cultural and demographic migrations between South and North America, the origins of agricultural practices, and the movement of languages and cultural elements across regions, particularly in relation to the cultivation of cacao and maize. The author emphasizes the need for a broader exploration of historical contexts, linguistic diversity, and the influence of migration on the development of civilizations.
