Chili Peppers - An American Domestication Story

Chili pepper (Capsicum spp. L., and sometimes spelled chile or chilli) is a plant which was domesticated in the Americas at least 6,000 years ago. Its spicy goodness spread into cuisines throughout the world only after Christopher Columbus landed in the Caribbean and took it back with him to Europe. Peppers are widely considered the first spice to have been used by humans, and today there are at least 25 separate species in the family of American chili peppers and over 35 in the world. Domestication Events At least two, and perhaps as many as five separate domestication events are thought to have occurred. The most common type of chili today, and likely the earliest domesticated, is Capsicum annuum (the chili pepper), domesticated in Mexico or northern Central America at least 6,000 years ago from the wild bird pepper (C. annuum v. glabriusculum). Its prominence around the world is likely because it was the one that was introduced into Europe in the 16th century AD. The other forms which may have been independently created are C. chinense (yellow lantern chili, believed to have been domesticated in northern lowland Amazonia), C. pubescens (the tree pepper, in the mid-elevation southern Andes mountains) and C. baccatum (amarillo chili, lowland Bolivia). C. frutescens (piri piri or tabasco chili, from the Caribbean) may be a fifth, although some scholars suggest it is a variety of C. chinense. The Earliest Evidence of Domestication There are older archaeological sites which include domesticated chili pepper seeds, such as Guitarrero Cave in Peru and Ocampo Caves in Mexico, ranging in age from 7,000-9,000 years ago. But their stratigraphic contexts are somewhat unclear, and most scholars prefer to use the more conservative date of 6,000 or 6,100 years ago. A comprehensive examination of the genetic (similarities among the DNA from different types of chilies), paleo-biolinguistic (similar words for chili used in various indigenous languages), ecological (where modern chile plants are found) and archaeological evidence for chile pepper was reported in 2014. Kraft et al. argue that all four lines of evidence suggest that chili pepper was first domesticated in central-east Mexico, near Coxcatlà ¡n Cave and the Ocampo Caves. Chili Peppers North of Mexico Despite chilis prevalence in southwestern American cuisines, the evidence for early use there is late and very limited. The earliest evidence of chili peppers in the American southwest/northwest Mexico has been identified in Chihuahua state near the site of Casas Grandes, ca AD 1150-1300. A single chili pepper seed was found at Site 315, a medium-sized adobe pueblo ruin in the Rio Casas Grandes Valley about two miles from Casas Grandes. In the same context--a trash pit directly underneath a room floor--was found maize (Zea mays), cultivated beans (Phaseolus vulgaris), cotton seeds (Gossypium hirsutum), prickly pear (Opuntia), goosefoot seeds (Chenopodium), uncultivated Amaranth (Amaranthus) and a possible squash (Cucurbita) rind. Radiocarbon dates on the trash pit are 760 /- 55 years before the present, or approximately AD 1160-1305. Cuisine Effects When introduced into Europe by Columbus, the chili launched a mini-revolution in cuisine; and when those chili-loving Spanish returned and moved into the Southwest, they brought the spicy domesticate with them. Chilies, a large part of central American cuisines for thousands of years, became most common north of Mexico in places where the Spanish colonial courts were most powerful. Unlike the other central American domesticated crops of maize, beans, and squash, chili peppers did not become part of southwestern US/northwestern Mexican cuisine until after Spanish contact. Researchers Minnis and Whalen suggest that the spicy chili pepper may not have fit into local culinary preferences until a large influx of colonists from Mexico and (most importantly) a Spanish colonial government affected local appetites. Even then, chilies were not universally adopted by all southwestern people. Identifying Chili Archaeologically Fruits, seeds and pollen of capsicum have been found in deposits at archaeological sites in the Tehuacan Valley of Mexico beginning about 6000 years ago; at  Huaca Prieta  in the Andean foothills of Peru by ca. 4000 years ago, at  Ceren, El Salvador by 1400 years ago; and in La Tigra, Venezuela by 1000 years ago. Recently, the study of  starch grains, which do preserve well and are identifiable to species, has allowed scientists to peg the domestication of chili peppers to at least 6,100 years ago, in southwestern Ecuador at the sites of Loma Alta and Loma Real. As reported in  Science  in 2007, the earliest discovery of chili pepper starches is from the surfaces of  milling stones  and in cooking vessels as well as in sediment samples, and in conjunction with microfossil evidence of arrowroot, maize, leren, manioc, squash, beans and palms.

Research Paper on Child Behavior Free Essays

Child Behavior As It Ages Michael Larson English Composition II Ensley Laruth 10/30/2012 Child Behavior As It Ages Many people have studied the effect of academic achievement and later career success. The focus of this paper will be on the work of Greg Duncan of Northwestern University and L Rowell Huesmann of the University of Michigan. These findings can help parents, teachers and behavioral scientists help disruptive students. We will write a custom essay sample on Research Paper on Child Behavior or any similar topic only for you Order Now The study shows that the way children act at a young age will reflect later in life and interfere with their ability to learn. I will also be using information found in five other sources throughout this paper. These sources include information on attachment issues in psychopathology and intervention, history of childhood behavior problems in biological relatives of boys with attention-deficit hyperactive disorder and conduct disorder and BPA tied to behavior problems within girls just to name a few (Atkinson, 2004). Childhood behavior has been slowly deteriorating over the past 28 years since I was a toddler. Growing up in the 80s it was socially acceptable to spank your child and children were taught to respect elders. Now children are oblivious to the respect that parents deserve and everything centers on their own needs. Throughout this paper many things have been explored such as: attachment issues in psychology, history of childhood behavior problems in biological relatives of boys with ADHD and conduct disorder, dealing with disrespect in your teenager, the seven keys to child obedience and how children’s bad behavior gives insight to academic achievements. New Research Suggest â€Å"New research suggests that children entering school with behavior problems, as a rule, can keep pace with classroom learning, but persistent behavior problems can be a strong indicator of how well these students adapt to the work world† (Duncan amp; Huesmann, 2007  ¶2). With this being said there are two separate studies resulting in two separate results when researching kindergartners and younger children compared to adolescents and 8th graders. â€Å"One study examined data from six large-scale studies of almost 36,000 preschoolers in which the same subjects were observed repeatedly over time. The research included two national studies of U. S. children, two multi-site studies of U. S. children, one study of children from Great Britain and one study of children from Canada† (Duncan amp; Huesmann, 2007  ¶2). There was various research techniques used in finding the results from all of the different studies. â€Å"Surprisingly, difficulty getting along with classmates, aggressive or disruptive behaviors, and sad or withdrawn behaviors in kindergarten did not detract from academic achievement in childhood and early adolescence† (Duncan amp; Huesmann, 2007  ¶3). There were several indicators studied, including picking fights, interrupting the teacher and defying instructions. Kindergartners that were involved in these acts did surprisingly well in 5th grade math and English, while keeping pace with well behaved children. Another CAPCA study, which examined older children, found such a connection. According to CAPCA investigator Rowell Huesmann, persistent behavior problems in eight-year-olds are a powerful predictor of educational attainment and of how well people will do in middle age† (Duncan amp; Huesmann, 2007  ¶3). Childhood behavior has been slowly deteriorating over the past 28 years since I was a toddler. Growing up in the 80s it was socially acceptable to spank your child and children were taught to respect elders. Now children are oblivious to the respect that parents deserve and everything centers on their own needs. Children of the current generation are losing the respect and behavior that was drilled into people of past generations. The purpose of this paper is to explain the importance of today’s society to increase awareness on the development of our children’s behavior and also to explain why harsh punishment can get children on track. The intended audience of this paper is current parents and expecting parents. The secondary audience will be future parents of our generation. I will be the voice of parents of our generation and future parents. Dealing With Disrespect In Your Teenager Disrespect can start small and turn into something much more serious if not tended to. It can become the way the child relates to family and friends; it can even be passed from generation to generation. Most parents do not stop this behavior for fear that it will effect the parent child relationship when they may actually be effecting the way the child relates to people in the future. â€Å"As any parent of a 13-year old  knows, disrespect can be displayed by the roll of their eyes, an arrogant attitude, a sideways look, a turned back, cutting or barbed comments, sarcasm, pouting, or raging. And nowadays, it can include popping in the iPod ear buds, texting on the cell phone or playing the video game instead listening to a parent† (Gregston, 2010,  ¶ 2). There is no hiding the sting of disrespect when your child shows signs of it and there is no need to point it out to the child because they know exactly what they were doing. The Seven Keys To Child Obedience Learning obedience is an important part of early child development. Obedience is the main tool parents use to train their children. Through obedience your child will use things he or she needs later in adulthood that force obedience upon a child will soon create resentment within their children, which will eventually lead to rebellion. According to Hareyan (2005), â€Å"Although you can punish a child for not obeying, this will not foster any long-term obedience. When the child reaches his teen years and becomes more independent, punishment will only serve to destroy the already faltering parent child relationship†(Hareyan, 2005,  ¶ 2). There are seven steps to getting your child to want to obey you. These steps according to the author are, â€Å" loving concern for the child, sincere respect for the child, patients, speak softly, make moderate demands, follow through and be free with yes but not with no† (Hareyan, 2005,  ¶ 3). History of Childhood Behavior Problems in Biological Relatives â€Å"Frick assessed the history of childhood behavior problems in the biological relatives of over 100 outpatient boys aged 7 to 12 years with attention-deficit hyperactivity disorder (ADHD) or conduct disorder (CD)† (Frick P, 1991 p1). Frick did this in order to see if these two disorders were something that is hereditary and passed down from relatives. The mothers, fathers, and other biological relatives of children with ADHD were significantly more likely to have a history of childhood ADHD but not problems of antisocial behavior or substance use in their childhood† (Frick P, 1991 pg1). ADHD is something that can be passed on through relatives but substance use or abus e was not a result of relatives having ADHD. This does not mean there will not be substance use but the study shows that it is not a result of family ADHD. â€Å"Attention deficit disorder with or without hyperactivity was similarly associated with a family history of ADHD†. On the other hand fathers of children with CD were more likely to have a history of CD and substance abuse, these results didn’t seem to change with the difference in race or social status. These results provide support for the independence of ADHD and CD being a clinical syndrome and not something inherited† (Frick P, 1991 p1). Attachment Issues In Psychopathology The report conducted by Atkinson and Goldberg report reviews and compares empirical findings on attachment and childhood behavior problems in normal, at-risk, and clinical studies. The report concludes that as we move along a continuous risk to clear diagnosis, the likelihood of attachment decreases and the likelihood of controlling, disorganized, and insecure attachment increase. Because these are normally rare patterns and, in the case of the disorganized and insecure-other categories, not clearly defined strategies, this is consistent with the notion that clinic samples include attachment patterns that fall outside of the established schemes. Further differentiation within these categories based on clinic samples may prove to be more useful than are the normatively derived classification schemes in linking attachment and psychopathology (Atkinson, 2004). Conclusion Throughout this paper many things have been explored such as: attachment issues in psychology, history of childhood behavior problems in biological relatives of boys with ADHD and conduct disorder, dealing with disrespect in your teenager, the seven keys to child obedience and how children’s bad behavior gives insight to academic achievements. With this information parents may have learned some new information about Attention-Deficit Hyperactive Disorder and Conduct Disorder, new ways to handle obedience with your children or the lack of obedience and the seven keys to child obedience. With this information childhood obedience can be improved throughout the world. Reference Atkinson L. amp; Goldberg S. (2004). Attachment Issues In Psychopathology And Intervention.
