Coxcatlan Cave
Coxcatlan Cave is a Mesoamerican archaeological site in the Tehuacán Valley, State of Puebla, Mexico. It was discovered by Richard MacNeish in the 1960s during a survey of the Tehuacán Valley. It was the initial appearance of three domesticated plants in the Tehuacan Valley (Puebla, Mexico) that allowed an evaluation to be done again of the overall temporal context of the plant domestication in Mexico. In addition to plants, Coxcatlan Cave also provided nearly 75 percent of the classified stone tools from excavation.Trigger, Bruce G., Wilcomb E. Washburn, and Richard E. W. Adams. The Cambridge History of the Native Peoples of the Americas. Cambridge, England: Cambridge UP, 1996. Print. Overview It was used over a span of 10,000 years, mostly during the Archaic period, as a shelter and gathering place during the rainy season for groups of foragers as large as 25–30 individuals. It is one of a collection of cave sites in the Tehuacan Valley. Each have similar archaeobota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoamerica
Mesoamerica is a historical region and cultural area in southern North America and most of Central America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. Within this region pre-Columbian societies flourished for more than 3,000 years before the Spanish colonization of the Americas. Mesoamerica was the site of two of the most profound historical transformations in world history: primary urban generation, and the formation of New World cultures out of the long encounters among indigenous, European, African and Asian cultures. In the 16th century, Eurasian diseases such as smallpox and measles, which were endemic among the colonists but new to North America, caused the deaths of upwards of 90% of the indigenous people, resulting in great losses to their societies and cultures. Mesoamerica is one of the five areas in the world where ancient civilization arose independently (see cradle of civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tres Zapotes
Tres Zapotes is a Mesoamerican archaeological site located in the south-central Gulf Lowlands of Mexico in the Papaloapan River plain. Tres Zapotes is sometimes referred to as the third major Olmec capital (after San Lorenzo Tenochtitlán and La Venta), but the Olmec phase is only a portion of the site's history, which continued through the Epi-Olmec and Classic Veracruz cultural periods. The 2000-year existence of Tres Zapotes as a cultural center is unusual, if not unique, in Mesoamerica.Pool, p. 250. Location The site is located near the present-day village of Tres Zapotes, west of Santiago Tuxtla, Veracruz at the western edge of the Los Tuxtlas Mountains on the banks of the Rio Hueyapan (a small stream). The area is a transition point between the Los Tuxtlas Mountains and the Papaloapan River delta and allowed the inhabitants to take advantage of the forested uplands as well as the swamps and streams of the flatlands. Scarcely to the east stands Cerro el Vigía, an extinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Sites In Puebla
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes ove ...

Cave Sites In Mesoamerican Archaeology
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...

Carbon-14
Carbon-14, C-14, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz N. D. Kurie, Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: carbon-12 (), which makes up 99% of all carbon on Earth; carbon-13 (), which makes up 1%; and carbon-14 (), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 () through bet ...

Pinto Bean
The pinto bean () is a variety of common bean (''Phaseolus vulgaris''). In Spanish they are called , literally "painted bean" (compare pinto horse). It is the most popular bean by crop production in Northern Mexico and the Southwestern United States, and is most often eaten whole (sometimes in broth), or mashed and then refried. Either way, it is a common filling for burritos, tostadas, or tacos in Mexican cuisine, also as a side or as part of an entrée served with a side tortilla or sopaipilla in New Mexican cuisine. In South America, it is known as the , literally "strawberry bean". In Portuguese, the Brazilian name is (literally " bean"; contrary to popular belief, the beans were not named after Rio de Janeiro, but after a pig breed that has the same color as the legume), which differs from the name in Portugal: . Additionally, the young immature pods may be harvested and cooked as ''green pinto beans''. There are a number of different varieties of pinto bean, notably some o ...

Squash (plant)
''Cucurbita'' (Latin for gourd) is a genus of herbaceous fruits in the gourd family, Cucurbitaceae (also known as ''cucurbits'' or ''cucurbi''), native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus ''Lagenaria'', which is in the same family and subfamily as ''Cucurbita'', but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the ''Cucurbita'' species. Most ''Cucurbita'' species are herbaceous vines that grow several meters in length and have tendrils, but non-vining "bush" cultivars of ''C. pepo'' and ''C. maxima'' have also been developed. The yellow or orange flowers on a ''Cucurbita'' plant are of two types: female and male. The female flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accelerator Mass Spectrometry
Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. 14C from 12C). The method suppresses molecular isobars completely and in many cases can separate atomic isobars (e.g. 14N from 14C) also. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as 10Be, 36Cl, 26Al and 14C. Their typical isotopic abundance ranges from 10−12 to 10−18. AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough. Other advantages of AMS include its short measuring time as well as its ability to detect atoms in extremely small samples. The method Generally, negative ions are created (atoms are ionized) in an ion source. In for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domesticated Plants Of Mesoamerica
Domesticated plants of Mesoamerica, established by agricultural developments and practices over several thousand years of pre-Columbian history, include ''maize'' and ''capsicum''. A list of Mesoamerican cultivars and staples: Maize Maize was domesticated in Western Mexico and Mesoamerican cultures expanded wherever it was cultivated. It became widespread in the Late Archaic Period and was grown wherever conditions allowed. The early use of maize focused on the consumption of unripened kernels. Before people settled into villages and began farming, the amount of time it took to invest in maize was too great. The output of wild maize did not justify the time and work needed to grow the crop. However, maize could be both dried and stored which was very important to early Mesoamericans as it could be used on a year-round basis. Drying meant that it could be transported as well. The common bean (''Phaseolus vulgaris'') was often grown with maize. These two plants provide complement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Olmec
The Olmecs () were the earliest known major Mesoamerican civilization. Following a progressive development in Soconusco, they occupied the tropical lowlands of the modern-day Mexican states of Veracruz and Tabasco. It has been speculated that the Olmecs derived in part from the neighboring Mokaya or Mixe–Zoque cultures. The Olmecs flourished during Mesoamerica's formative period, dating roughly from as early as 1500 BCE to about 400 BCE. Pre-Olmec cultures had flourished since about 2500 BCE, but by 1600–1500 BCE, early Olmec culture had emerged, centered on the San Lorenzo Tenochtitlán site near the coast in southeast Veracruz. They were the first Mesoamerican civilization, and laid many of the foundations for the civilizations that followed. Among other "firsts", the Olmec appeared to practice ritual bloodletting and played the Mesoamerican ballgame, hallmarks of nearly all subsequent Mesoamerican societies. The aspect of the Olmecs most familiar now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
