It is a pity that more and more researchers, who had shown their serious evidence, are being driven by the need for an ever-harder competition, especially in countries like the United States where they are not insured of their jobs, to produce at all costs, new and sensational, which has so far been the only thing of professional journalists; to be cautious, though, assumptions are usually made, but likely to discover new ways of research, they procure fashionable subjects to reinterpret in their own way material which has already been the subject of many work. That's a little what happens to Mrs. Dobkin de Rios, who authorises her comments on the current use of hallucinogenic plants to make new assumptions about the signification of the mochica ecography. It is therefore possible, from biological data on Lima bean, to imagine all possible uses of genetic hazards, either to divinatory puroses or also to attribute certain varieties to either side of competitive forces. Not to mention that Phaseolus lunatus contains in the wild state hydrocyanic acid that man has tried to eliminate in cultivated forms but can reappear especially in substantial varieties that are escaped from crops. It can also be imagined that these substantial forms that appeared on the edge of the field, i.e. on the edge of the desert, could be considered to be both as a reservoir of new varieties and as a link between cultivated and wild. It is not always necessary to take hallucinogens to dream !
