INTRODUCTION Our article title is “The Origin of the Naked Grains of Maize” which introduces the research performed to explain one aspect of the large variation between maize and Mexican teosinte from which maize was domesticated. The paper goes into how maize has evolved from teosinte and the genetic experimentation performed in order to demonstrate that maize evolved from teosinte. This is an interesting research topic because both of their genotypes are so similar yet their phenotypes are so dramatically different that it resulted in a question of whether maize did in fact evolve directly from teosinte and are members of the same species (Zea Mays) or if it is just a completely different species. Plant Morphology: In order to fully understand the research done in the article, one must be familiar with general plant morphology. Plant morphology basically means the structure of the plant and in our case, the form of corn plants. First off, all plants consist of three different parts: roots, stems and leaves. However, it should be remembered that even though all plants may consist of these three parts, this does not mean that the stems, leaves, and roots of each plant will look the same as the next. Therefore, this should also be noted when viewing Zea Mays plants as well; not all corn plants are going to look the same. We can show this by comparing the physical differences of maize and teosinte. Modern maize presents itself with a single primary shoot which is a stem with all of its leaves, whereas teosinte presents itself with many lateral branches that have their own sets of leaves attached to them. Another major difference is that Teosinte’s fruit (the individual kernels) is enclosed within a stony... ... middle of paper ... ...ersity Genetics Department. 2 Aug 2004.

As the class discussed in lecture, the myth created a personalized connection between the Native Americans and the Earth and allowed the Native Americans to identify with their landscape. Because they believed that corn came from recycled human flesh, they could see it as an animate, personalized being, rather than just an object. Merchant explains how the Native Americans also believed, because of the Corn Mother, that “the Earth would continue to regenerate the human body through the corn plant.” This shows that rather than just seeing corn as an object to cultivate, it was a sacred gift given to them by the land. Because the land gave the gift of corn to them, they believed the land should be treated with
Evidence has shown that the corn we know today is quite different from the first time it was domesticated in Mexico. Although researchers and the academic world acknowledge that corn began its world journey in Mexico, they are unsure as to the time and location of the earliest domestication (American Society of Plant Biologist). Through genetics, teosinte is found to be corn’s wild ancestor. Although the two do not look much alike, at a DNA level they are surprisingly alike, such as having the same number of chromosomes and a remarkably similar arrangement of genes (The University of Utah).
Since the birth of agriculture farmers across the world have been altering the genetic makeup of the crops they grow. Ancient farmers chose only the best looking plants and
Corn tortillas are a very important component of the Mexican and Central American diet. They date back several thousands of years. However, there is no clear record of their origin. According to the Mayan creation legend, when the gods decided to create man they tried using different materials but the only material that worked was corn. Quetzalcoatl descended to Mictlán, the place of the dead. From there, he took some bones and went to the goddess, Coatlicue. The goddess grinded the bones together with corn, creating the dough that Quetzalcoatl turned into humans, thus Mayan men are “men of corn”. As the story demonstrates, there is a strong emphasis on corn and its by-products in this region. Ultimately, tortillas partake in several components of the biocultural framework that affect the nutritional status of this population.
Physical achievements by Mesoamerican Indians include the floating garden cities created in lakes for protection against attacks. These also allow for fertile growing of plants as recorded by Spanish conqueror Hernan Cortes in Document 5. Tehuacan was also the site of the first planting of corn around 8000 B.C.E. as depicted by the image in Document 7.
Upon arrival in the Americas, Europeans set out to make wheat the standard grain in the lands they had discovered; the establishment of wheat was both functional, as it was a staple of the European diet, as well as an attempt to institutionalize European control. While wheat did gain some ground in the Americas, especially among the upper classes, it failed to surmount maize as the “the foundation of indigenous livelihood.” The persistence of maize as a staple of the indigenous way of life is not shocking, as J. Eric Thompson writes: “Maize was a great deal more than the economic basis of Maya civilization: it was the focal point of worship, and to it every Maya who worked the soil built a shrine in his own heart.” The Americas were not
The Aztec empire was a complex civilization that practiced agriculture, imposed a hierarchy system, and practiced cultural events involving religion, various gods, and rituals. Agriculture in the Aztec empire was complex, required knowledge of flora, farming techniques, and local environment. The process was “more elaborate than just throwing a few seeds on the ground and waiting for a stalk to sprout up” (Blanton, Kowalewski, Feinman, Finsten, 1993); it was essential to grow enough food to feed an entire population. The most important and common crop grown was maize, also known as corn, which could be manipulated in various ways to yield products of varying tastes and textures; tortillas, tamales, atole, and maize gruel to name a few (Zizumbo-Villarreal, 2010). Maize was an ideal grain to keep around, not only did it provide nutrients to its consumers, it could be eaten raw or stored for months without spoiling.
This research plans to compare and contrast the similarities and differences in agricultural development between the Jericho Valley,in present day Palestine, and that of the Andes Mountains. There are several aspects to compare in these regions. First and perhaps most obvious is the environmental differences of these regions as well as the ecological changes in each region has itself undergone. Closely linked to these environments is the native biological species, how these native species have been domesticated, as well as looking at what crop species have been introduced to the regions, and their effect on the native species. After explaining the differences in climate of the two regions it is important to understand who was doing the farming in these areas. This will be looked at in terms of cultural evolution, groups' social approach to farming and how that affects land use and technical procedure.

The Popol Vuh doesn’t fall short in referencing and glorifying maize. One such reference in the Popol Vuh categorizes maize as a way to determine fate; if an ear of maize is planted and dries up, it indicates death. The article, “The Flowering of the Dead” concludes, “In Atiteco religion, ‘Flowering Mountain Earth’ is a place at the world’s centre whose primary manifestation is a maize plant or tree.” (Carlsen 27). A “Flowering Mountain Earth” is the center of the world that represents life, beauty, and the gods. Among this place, maize is an important object that animates and projects the qualities of a Flowering Mountain Earth. Maize is axis mundi, the center of the world. It is a staple crop in the Maya people; it is essential to the people and heavily relied on. The Maya saw maize as a fetish that truly gave them everything. Without it, everything that ties the Maya together falls apart. Successful growth of maize represents the life and well-being of the Maya, while a dying maize plant all but points to death and the failure of civilization. It is with the importance of maize in Maya culture, that it is omnipresent throughout the Popol
Before the land of what we no class Turkey, Iraq, Jordan, and other countries in the middle east grains, such as wheat and wild barley, could be seen growing in the wild without human hand to cultivate and nurture it (Authors 2007). Over time, humans began to recognize the benefit of the plants and began the first signs of human agriculture. The skill of farming took time and trial and error, but along the way, humans began to settle down to tend to their crops. Though the first crops were nothing more than seed s thrown about without rhyme or reason to the process we know today such as fields having, rows and sorting out the seeds to create a higher yield each harvest (Authors 2007). Because of the trial and error process, agriculture of plants did not take place of a short period but took many, many years to evolve to what we know today as agriculture; the new fa...

Barley is a very important grain in the world today. It is very versatile in every way. It has been well adapted through its evolution. It has a very mysterious and much debated beginning. Now however, barely has become well known and so have its many uses. Barley, which is of the genus Hordeum, is a cereal that belongs to the grass family Poaceae. Barley has many different varieties. The most common is Hordeum vulgare, which is a six-rowed type of barley that has a spike notched on opposite sides with three spikelets on each notch. At each notch there is a flower or floret that later develops into a kernel. Hordeum distichum is a two-rowed type of barley that has central florets producing kernels and it has lateral florets that are sterile. Lastly there is Hordeum irregulare which has fertile central florets and different arrangements of sterile and fertile lateral florets. This is the least cultivated species of the three main forms (2).
