And I would add that there is the possiblity that the culture that domesticated mexican bean may have been brought from asia 10,000 years ago, a similar lental was found in the Jomon pots of Japan, the evidence I saw dated to the early Jomon period about 13000 years ago. The same lentil was found close to a paleoamerind tool kit in alaska but did not persist in that region/ http://www.indiana.edu/~origins/teach/P380/P380Agric.html There is some argumentation as to when Jomonese had agriculture; however by the middle Jomon period they are practicing slash and burn preparation for agriculture. There is a huge debate whether the planted crops within natural settings as a number of Jomon pots were uncovered that looked to be long term storage of lentils. Many people offer up the Jomon as the only pottery producing culture that was not agricultural; however I beleive that they practiced a form of agriculture that was compatible with the 'most luxiorious hunter gatherer' culture in the world. They did not become dominantly agricultural simply because this was not as productive as light agriculture. Again I think they had been playing with these legumes for at least 10,000 years. PLANT GENETIC RESOURCES Genetic Diversity and Population Structure of Wild Lentil Tare. Man Kyu Huh* and Hong Wook Huh " In the hierarchical analysis, the large variance exhibited among populations with respect to regions and a large component of the value was explained by variance among regions with respect to the total , a result consistent with the strong geographic effect indicated by UPGMA and Mantel's test (the correlation between geographic and genetic distances). Although genetic diversity was not significantly correlated with regions (rs = 0.514, Spearman rank correlation), measures of genetic diversity for the Japanese populations were lower than those for Korean populations (Table 1). As revealed by earlier studies (Yamamoto and Plitmann, 1980; Potokina, 1997; Weber and Schifino-Wittman, 1999; Zhang and Mosjidis, 1998), the genus Vicia could have originated in the Mediterranean region and Western Asia. If this hypothesis is correct, it is possible that the Japanese V. tetrasperma populations trace to introductions from Western Asia via Korea or China. " " Identification of the lentil‘s wild genetic stock Ladizinsky G.1 1.Hebrew University, Faculty of Agriculture, P.O. Box 12, Rehovot 76100, Israel (E-mail: [EMAIL PROTECTED]) ?? The origin of lentil from the taxon Lens culinaris subsp. orientalis has been proved by morphological evidence and breeding experiments. This wild form exhibits variation in many characters and is distributed over a vast area from the Middle-East to central Asia. Characters that are polymorphic in the wild progenitor but monomorphic in the cultigen can be utilized for better identification of the genetic stock which gave rise to the domesticated lentil. Three characters of that kind have been identified in lentil: chromosomal architecture, crossability potential and restriction pattern of chloroplast DNA. Nearly all accessions of the cultivated lentil tested to these three characters have been found monomorphic, but considerable polymorphism exists in the wild accessions. Three subsp. orientalis accessions have been shown to share the above characters with the cultigen and hence can be regarded as members of the genetic stock from which lentil was domesticated. These three accessions originated from eastern Turkey and northern Syria. " Interpretation, Japanese and Korean so-called wild lentils are to genetically homogenous to be consider as longer term local derivatives, they were likely introduced by humans. The appear in association with Jomon pots about 13,000 years ago. And I understand from my wife that the wild Japanese lentil grows best on the island of Hokkaido, were apparently the first non-oceanian/southeast asia humans first arrive in Japan. So according to the experts Jomonese conducted agriculture late, but the the seeds found in their Jomon pots came from turkey and probably with them. Uhm I think someone is missing an important connection here. lol. I beleive this lentil was first found in association with toolkits in alaska. It is possible that related peoples brought the legumes to the new world but found they did not prosper in south american, as a result they cultivate species in south america. " Structure of Genetic Diversity among Common Bean Landraces of Middle American Origin Based on Correspondence Analysis of RAPD S. Beebea, P.W. Skrochb, J. Tohmea, M.C. Duquea, F. Pedrazaa and J. Nienhuisb a Centro Internacional de Agricultura Tropical (CIAT), A.A. 6713, Cali, Colombia b Univ. of Wisconsin-Madison, Dep. of Horticulture, 1575 Linden Drive, Madison, WI 53706-1590 USA More than 60% of common bean production worldwide is derived from cultivars of Middle American origin. Understanding the diversity of these will facilitate their use in genetic improvement. The objective of this study was to analyze a collection of 269 landraces of common bean (Phaseolus vulgaris L.) by correspondence analysis of random amplified polymorphic DNA (RAPD) data to determine the genetic structure of the Middle American gene pool of cultivated bean. One hundred eighty landraces originating in Mexico, the remainder in Central America and secondary centers of diversity within the Americas, and two checks were studied. DNA was extracted, RAPD reactions carried out, and polymorphic bands were scored as present or absent on the basis of 39 primers. Groups were formed which in part corresponded to races defined previously by morphological and agroecological criteria. However, tropical small-seeded Race M was composed of two groups: one largely Mexican that included most small-seeded black beans of upright plant habit; and one Central American with landraces of various seed colors. Most non-black small-seeded germplasm of Race M phenotype from secondary centers grouped with the Central American landraces, except for cream-seeded and purple-seeded accessions from Brazil. Races D and J could be distinguished and within races D and J further divisions could be recognized which were related to geographic origin. The more commercial Race D landraces formed a genetic group that was predominant in the western part of the Mexican highland plateau. Another Race D group was concentrated at the eastern extreme of the neovolcanic axis and was differentiated morphologically as well. Guatemalan germplasm contained accessions of climbing bean that did not group with any of the previously defined races and should be considered a separate race. Thus, Middle American germplasm of common bean is more complex than previously thought, and contains diversity that remains to be explored for its practical value. " " Lectin and lectin-related proteins in lima bean (Phaseolus lunatus L.) seeds: biochemical and evolutionary studies. Sparvoli F, Lanave C, Santucci A, Bollini R, Lioi L. Istituto Biosintesi Vegetali, Milano, Italy. Lectin-related polypeptides are a class of defence proteins found in seeds of Phaseolus species. In Lima bean (P. lunatus), these proteins and their genes have been well characterized in the Andean morphotype, which represents one of the two gene pools of this species. To study the molecular evolution of the lectin family in Lima bean we characterized the polypeptides belonging to this multigene family and cloned the genes belonging to the Mesoamerican gene pool. The latter gene pool contains components similar to those of the Andean pool, namely: an amylase inhibitor-like (AIL), an arcelin-like (ARL) lectin and the less abundant Lima bean lectin (LBL). These proteins originate from an ancestor gene of the lectin type which duplicated to yield the lectin gene and the progenitor of ARL and AIL. In this species. ARL represents an evolutionary intermediate form that precedes AIL. Phylogenetic analysis supports an Andean origin for Lima bean. The molecular evolutionary studies were extended to the genes of common bean and demonstrated that true lectin genes and the ancestor of lectin-related genes are the result of a duplication event that occurred before speciation. Lima and common bean followed different evolutionary pathways and in the latter species a second duplication event occurred that gave rise, in Mesoamerican wild genotypes, to arcelin genes. " IOW Phaseoli beans were domesticated 2x in mesoamerica and andean bean were domesticated separately. No cultivar connection between mesoamerican bean domestication and andean. Therefore not only was the bean domesticated once in the new world, it was domesticated at least 3 times. In fact this appears to be a common theme in asian as well as Native american agriculture, while Japanese tended to grow crops domesticated elsewhere it appears that the Jomonese tended to focus on legumes that were best suited to climates of different regions. While the lentil appears to have reached alaska, the legume consumption of native americans of north american appears to be focused on regionally adaptive varieties. Jomonese had in use many varieties of the Vigna sp. and most of these were wild stocks developed locally. By comparison, a number of native american medicines and recreational hallucinagens come from the beans of legumes specific to north america. Thus it appears there was a transition between the cultivars that putatively arose in syria and the use of legumes from the Jomon to south america. It is possible that the radical change in climate north of hokkaido forced people to adapt or the lentils of the old world simply could not withstand the insects/diseases of the new world. One of the things I noted in reading the literature is some of the east asian and native american cultivars have substantially higher levels of phytotoxins than do the old world cultivars, suggesting that these cultivars, while more adverse to human consumption than old world cultivars had substantially higher survivability in the new world. The above theory would make sense, it appears that the mexican bean was domesticated in many places in the new world suggesting that the planting of the beans was something that native americans anticipated their domesitication. Each of the native cultivars appears to be resistant to insects and disease that are abundant in the areas where they were domesticated. IOW the americas were a tough place if you are a legume, the pharmoactive properties of these legumes may be a result of the selection. In addition the diversity of beans in each cultigroup is deep suggesting that domestication occurred early in mesoamerican culture. Note All domesticars of the mexican bean originated from the new world. In addition while bovidae meat was the protein staple of the middle eastern/meditteranean diet, the mesoamerican diet is distinct and similar to Jomonese in the use of both fish and legume as the staple of the diet, and decrease of ground foraging herbavores. Only part of the northern Jomonese appeared to be heavily dependent on large game predation. The presence of acorns in the Jomonese diet indicates that the presence of trees in Japan was a factor selected into what cultivars might have been grown early on. Again this is comparable to the situation in mesoamerica mesoamericans have a deep rooted adaptation toward more vegetarian diets with many cultivars and a lower reliance on range animals. Range animals being primarily important close to the Rio Grande and in the highlands, wereas in the forest there tends to be a greater variety of animals (fewer mammalian biomass, more reptilian, avian) as well as more arboreal mammals that result in less food per kill. Thus the similarities of these two cultures could be the result of common cultural relationship with the Jomonese or it could be the result of adaptation to the heavily forested environment with complex terrain where large range animals were not present in a monotonous abundance. IOW I think you are right to infer the mesoamerican cultivars are probably older than we give credit, corn may be a later domesticant and other crops like beans, which are more useful as a staple in a mostly vegetarian diet relative to corn may have been domesticated first. >http://anthroclass.com/lectures/sbarch8/class8.html >The Tehuacan Valley of Mexico has been extensively studied over the past >30 years by archaeologists looking and subsistence changes.

The genetic evidence indicates beans were domesticate well before this. >So there goes his irrigation claim. Doug, with all due respect to the above, in looking at the archaeologist interpretation of Jomon agriculture I found many instances of Archaeologist blowing off Jomon agriculture despite evidence of slash and burn agriculture, the fact they had pottery and despite the fact that the sorted seeds of various types into this pottery. The some types of legumes found clearly indicates that at least one seed was brought from central asia and planted, if not routinely planted from 13,000 years ago. Thus absolute proof of agriculture may not do justice to indirect correlates of agriculture. And in Japan it begs the question, agriculture did not bloom because people lack the ability to convert their culture, or was the culture so successful as mostly H/G that non-destructive (or non-sustainable) agriculture was marginally more productive than what they were doing. The staple of mesoamerican diet probably shifted with corn and this was probably the result of a longer domestication history, suggesting that a 'full'-out grain agriculture may be something only plausible after trial and error process with some of the more aggressively producing crop species. If we remove corn from the mesoamerican picture do we say this is an non-agrarian society because grain production is the standard of measuring agrarian society or does agrarian societies begin once the first seeds are carried from point a to point b with the intent of planting them and harvesting the seeds.
