El Riego Phase
The El Riego phase is a Mexican archaeological period in the Tehuacan Valley Sequence that came to pass during the early part of the Archaic period in the Americas. The El Riego phase is the second period in the sequence; preceding it was the Ajuereado phase, and the Coxcatlan phase came later. Dating for the El Riego phase differs slightly from source to source, it has been said to have occurred from as wide a span as 8650 - 5700 BCEvans, Susan Toby (2008).

Archaeological
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, 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 over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Projectile Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 archaeobotanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodworking
Woodworking is the skill of making items from wood, and includes cabinet making (cabinetry and furniture), wood carving, woodworking joints, joinery, carpentry, and woodturning. History Along with Rock (geology), stone, clay and animal parts, wood was one of the first materials worked by early humans. Lithic analysis, Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among early finds of wooden tools are the worked sticks from Kalambo Falls, Clacton-on-Sea and Lehringen. The spears from Schöningen (Germany) provide some of the first examples of wooden hunting gear. Flint tools were used for carving. Since Neolithic, Neolithic times, carved wooden vessels are known, for example, from the Linear Pottery culture water well, wells at Kückhofen and Eythra. Examples of Bronze Age woo ...

Weaving
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. (''Weft'' is an Old English word meaning "that which is woven"; compare ''leave'' and ''left''.) The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms. The way the warp and filling threads interlace with each other is called the weave. The majority of woven products a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Tool
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric (particularly Stone Age) cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction. One simple form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abejas Phase
The Abejas Phase, also known as the Late Archaic, is the fourth phase of the Tehuacán Valley of Mexico sequence, dating from 3825 to 2600 BC. Although the Tehuacán Valley sequence of phases has become one of the most famous phase sequences for any region in Mesoamerica, very few sites from these phases are known. Description Following the Ajuereado, El Riego, and the Coxcatlan phase, and followed by the Purron and Ajalpan phases, Abejas is the fourth of six phases. The Abejas phase population may have been twice as large as its preceding phase, Coxcatlan. This period is marked by the appearance of campsites and permanent settlements installed on river terraces, a noticeable decline in reliance on wild foods, domestication of plants (maize, beans, squash), and the appearance of long obsidian blades During this phase, agriculture supplies 25% of food requirements. Also during this phase, new material culture innovation arose such as split-stitch basketry, stone bowls and jars. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avocado
The avocado (''Persea americana'') is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated by Mesoamerican tribes more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large berry containing a single large seed. Avocado trees are partially self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year. The fruit of domestic varieties have smooth, buttery, golden-green flesh when ripe. Depending on the cultivar, avocados have green, brown, purplish, ...
