Guest guest Posted August 30, 2007 Report Share Posted August 30, 2007 hi shirish wheat is relatively new in human evolution - there's no denying this, but perhaps we ned to clarify the issue of human evolution please remember the time-scale for the evolution of Homo sapiens is much greater than the time we have been eating grain (see discussion below) as far as the claim that wheat is genetically modified, we have to get clear on what we mean by this humans have been genetically modifying crops from the very beginning, with the hep of nature, through selection and crossing, which is why there are over 20 different species of wheat, including emmer, spelt, kamut and durum what you are likely referring to however is genetically engineered organisms or GEO (i.e. a technique using recombinant DNA technology), and this is a phenomena that is exclusive to the late 20th century, beginning with the 'flavr-savr' tomato in 1994 for whatever reason GMO has become synonymous with GEO, but technically speaking, GMO would include natural cross-breading that humans have been using ever since the domestication of crops as of this time, there is NO GENETICALLY ENGINEERED WHEAT (i.e. " GMO " ) in commercial production anywhere in the world, and from reading press reports Monsanto has apparently dropped its plans to market a round-up ready wheat in 2004 so, as you can see, the claim that allergies and sensitivities to wheat are because they are GEO/GMO are simply not true, and i for one, sincerely hope you will stop promulgating this gross inaccuracy which borders on intellectual dishonesty There are 8 major cereal grains which are consumed by modern man (wheat, rye, barley, oats, corn, rice, sorghum, and millet) [Harlan 1992]. Each of these grains were derived from wild precursors whose original ranges were quite localized [Harlan 1992]. Wheat and barley were domesticated only ~10,000 years ago in the Near East; rice was domesticated approximately 7,000 years ago in China, India, and southeast Asia; corn was domesticated 7,000 years ago in Central and South America; millets were domesticated in Africa 5,000-6,000 years ago; sorghum was domesticated in East Africa 5,000-6,000 years ago; rye was domesticated ~5,000 years ago in southwest Asia; and oats were domesticated ~3,000 years ago in Europe. Consequently, the present-day edible grass seeds simply would have been unavailable to most of mankind until after their domestication because of their limited geographic distribution. Also, the wild version of these grains were much smaller than the domesticated versions and extremely difficult to harvest [Zohary 1969]. How recent in the human evolutionary experience is grain consumption in terms of our total dietary experience? The first member of the human genus, Homo, was Homo habilis who has now been dated to ~2.33 million years ago (MYA) [Kimbel et al. 1996]. Homo erectus, who had post-cranial (the rest of the body below the skull) body proportions similar to modern humans, appeared in Africa by about 1.7 MYA and is thought to have left Africa and migrated to Asia by 1 MYA or perhaps even earlier [Larick and Ciochon 1996]. Archaic Homo sapiens (called by some, Homo heidelbergensis) has been dated to 600,000 years ago in Africa and to about 400,000 years ago in Europe or perhaps earlier [De Castro et al. 1997]. Anatomically modern Homo sapiens appear in the fossil record in Africa and the Mideast by about 90,000-110,000 years ago and behaviorally modern H. sapiens are known in the fossil record by ~50,000 years ago in Australia and by about ~40,000 yrs ago in Europe. The so-called " Agricultural Revolution " (primarily the domestication of animals, cereal grains, and legumes) occurred first in the Near East about 10,000 years ago and spread to northern Europe by about 5,000 years ago [Cavalli-Sforza et al. 1993]. The industrial revolution occurred roughly 200 years ago, and the technological revolution which brought us packaged, processed foods is primarily a development that has occurred in the past 100 years and has seen enormous growth in the last 50 years. To gauge how little geologic or evolutionary time humans have been exposed to foods wrought by the agricultural revolution, let's do a little paper experiment. Take a stack of computer paper (the kind in which each page is connected to one another) and count out 212 eleven- inch (28-cm) pages. Then unravel the stack of paper and lay it out end to end--it will form a continuous 194-foot (59-meter) strip. Now, let's assume that 1 inch (2.54 cm) equals 1,000 years in our 194-foot strip of computer paper; thus, the first part of the first page represents the emergence of our genus 2.33 MYA and the last part of the last page represents the present day. Now, take a slow walk down all 194 feet of the computer paper, and carefully look at each of the individual eleven-inch sections. When you get to the very last eleven-inch section (the 212th section), this represents approximately the beginning of agriculture in the Mideast 10,000 years ago; therefore, during the preceding 211 sheets humanity's foods were derived from wild plants and animals. This little experiment will allow you to fully grasp how recent in the human evolutionary experience are cereal grains (as well as dairy products, salt, and the fatty meats of domesticated animals). Humans may have indeed eaten these foods for " millennia, " but millennia (even 10 millennia) in the overall timeframe of human existence represents 0.4%. Because the estimated amount of genetic change (0.005%) which has occurred in the human genome over this time period is negligible, the genetic makeup of modern man has remained essentially unchanged from that of pre-agricultural man [Eaton et al. 1985]. Consequently, the human genome is most ideally adapted to those foods which were available to pre-agricultural man, namely lean muscle meats, limited fatty organ meats, and wild fruits and vegetables--but, significantly, not grains, legumes, dairy products, or the very high-fat carcasses of modern domesticated animals. http://beyondveg.com/cordain-l/grains-leg/grains-legumes-1a.shtml#late %20role Caldecott, Dip.
