Maya civilizationThe Maya civilization (ˈmaɪə) was a Mesoamerican civilization that existed from antiquity to the early modern period. It is known by its ancient temples and glyphs (script). The Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. The civilization is also noted for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador.
Mesoamerican languagesMesoamerican languages are the languages indigenous to the Mesoamerican cultural area, which covers southern Mexico, all of Guatemala and Belize and parts of Honduras and El Salvador and Nicaragua. The area is characterized by extensive linguistic diversity containing several hundred different languages and seven major language families. Mesoamerica is also an area of high linguistic diffusion in that long-term interaction among speakers of different languages through several millennia has resulted in the convergence of certain linguistic traits across disparate language families.
Pre-Columbian eraIn the history of the Americas, the pre-Columbian era spans from the original settlement of North and South America in the Upper Paleolithic period through European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures. Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies.

TreeIn botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight.
FlavonoidFlavonoids (or bioflavonoids; from the Latin word flavus, meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6.
Agriculture in MesoamericaAgriculture in Mesoamerica dates to the Archaic period of Mesoamerican chronology (8000–2000 BC). At the beginning of the Archaic period, the Early Hunters of the late Pleistocene era (50,000–10,000 BC) led nomadic lifestyles, relying on hunting and gathering for sustenance. However, the nomadic lifestyle that dominated the late Pleistocene and the early Archaic slowly transitioned into a more sedentary lifestyle as the hunter gatherer micro-bands in the region began to cultivate wild plants.
Mesoamerican chronologyMesoamerican chronology divides the history of prehispanic Mesoamerica into several periods: the Paleo-Indian (first human habitation until 3500 BCE); the Archaic (before 2600 BCE), the Preclassic or Formative (2500 BCE – 250 CE), the Classic (250–900 CE), and the Postclassic (); as well as the post European contact Colonial Period (1521–1821), and Postcolonial, or the period after independence from Spain (1821–present). The periodisation of Mesoamerica by researchers is based on archaeological, ethnohistorical, and modern cultural anthropology research dating to the early twentieth century.
IquitosIquitos (ɪˈkɪtɒs,iː-,-toʊs; iˈkitos) is the capital city of Peru's Maynas Province and Loreto Region. It is the largest metropolis in the Peruvian Amazon, east of the Andes, as well as the ninth-most populous city in Peru. Iquitos is the largest city in the world that cannot be reached by road that is not on an island; it is only accessible by river and air. It is known as the "capital of the Peruvian Amazon". The city is located in the Great Plains of the Amazon Basin, fed by the Amazon, Nanay, and Itaya rivers.
TanninTannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term tannin (from Anglo-Norman tanner, from Medieval Latin tannāre, from tannum, oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term tannin is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules.
