Question: What Mesoamerican people founded the Yucuita site?

Context paragraphs:
Cannibalism in pre-Columbian America: There is universal agreement that some Mesoamerican people practiced human sacrifice and cannibalism, but there is no scholarly consensus as to its extent.

Nicarao people: The Nicarao people were a Nahuat-speaking Mesoamerican people that migrated from central and southern Mexico over the course of several centuries from approximately 700 AD onwards.  Around 1200 AD, the Nicarao split from the Pipil people and moved into what is now Nicaragua.  The migration of the Nicarao has been linked to the collapse of the important central-Mexican cities of Teotihuacan and Tula, as well as the Classic Maya collapse.  The Nicarao settled in several pockets throughout western Nicaragua, particularly around the western shores of Lake Nicaragua.  The Nicarao shared many cultural traits with their Aztec cousins, including an identical calendar, the use of screenfold books, the worship of closely-related deities, and the practice of human sacrifice.

Maya maize god: Like other Mesoamerican people, the traditional Mayas recognize in their staple crop, maize, a vital force with which they strongly identify.  This is clearly shown by their mythological traditions.  According to the 16th-century Popol Vuh, the Hero Twins have maize plants for alter egos and man himself is created from maize.  The discovery and opening of the Maize Mountain - the place where the corn seeds are hidden - is still one of the most popular of Maya tales.  In the Classic period (200-900 AD), the maize deity shows aspects of a culture hero.

Vanilla: Vanilla is a flavoring derived from orchids of the genus "Vanilla", primarily from the Mexican species, flat-leaved vanilla ("V. planifolia").  The word "vanilla", derived from "vainilla" , the diminutive of the Spanish word "vaina" ("vaina" itself meaning sheath or pod), is translated simply as "little pod".  Pre-Columbian Mesoamerican people cultivated the vine of the vanilla orchid, called "tlilxochitl" by the Aztecs.  Spanish conquistador Hernán Cortés is credited with introducing both vanilla and chocolate to Europe in the 1520s.

Acolhua: The Acolhua are a Mesoamerican people who arrived in the Valley of Mexico in or around the year 1200 CE.  The Acolhua were a sister culture of the Aztecs (or Mexica) as well as the Tepanec, Chalca, Xochimilca and others.

List of chocolate drinks: This is a list of notable chocolate drinks.  Chocolate is a processed, typically sweetened food produced from the seed of the tropical "Theobroma cacao" tree.  Its earliest documented use is by the Olmecs of south central Mexico around 1100 BC.  The majority of Mesoamerican people made chocolate beverages, including the Maya and Aztecs, who made it into a beverage known as "xocolātl" ] , a Nahuatl word meaning "bitter water."

Milpa: Milpa is a crop-growing system used throughout Mesoamerica.  It has been most extensively described in the Yucatán peninsula area of Mexico.  The word "milpa" is derived from the Nahuatl word phrase "mil-pa", which translates into "maize field."  Though different interpretations are given to it, it usually refers to a cropping field.  Based on the ancient agricultural methods of Maya peoples and other Mesoamerican people, "milpa" agriculture produces maize, beans, and squash.  The milpa cycle calls for 2 years of cultivation and eight years of letting the area lie fallow.  Agronomists point out that the system is designed to create relatively large yields of food crops without the use of artificial pesticides or fertilizers, and they point out that while it is self-sustaining at current levels of consumption, there is a danger that at more intensive levels of cultivation the milpa system can become unsustainable.

Tepanec: The Tepanecs or Tepaneca are a Mesoamerican people who arrived in the Valley of Mexico in the late 12th or early 13th centuries.  The Tepanec were a sister culture of the Aztecs (or Mexica) as well as the Acolhua and others—these tribes spoke the Nahuatl language and shared the same general pantheon, with local and tribal variations.

Mixtec: The Mixtec , , or Mixtecos, are indigenous Mesoamerican peoples of Mexico inhabiting the region known as La Mixteca of Oaxaca and Puebla as well as the state of Guerrero's Región Montañas, and Región Costa Chica, which covers parts of the Mexican states of Oaxaca, Guerrero and Puebla.

Yucuita: Yucuita (Mixtec: "Yúku'ita", meaning "Hill-flower", or "Hill of Flowers") is an archaeological site located in the Mixtec municipality of San Juan Yucuita in the Mexican state of Oaxaca.  It was founded by the Mixtec civilization in the pre-Classic Period as a small village dedicated to agriculture and obsidian.
