¿De dónde proviene el árbol de cacao? Mesoamérica o Alto Amazonas La historia ha ubicado a Mesoamérica como la región del origen del árbol de cacao sin embargo estudios realizados por botánicos y genetistas lo ubican en el Alto Amazonas, cerca de los límites entre Perú, Ecuador, Colombia y Venezuela.
