Document Summary
Center of origins concept is that vavilov proposed that crops originated where ther diversity of their relatives is greatest. This makes sense, a place where wild relatives are there, would have more abundant relatives. Lysenko proposed that plants exposed to the winter, would cause plants to remember winters and when it had flowered. This problem posed that genetic factors would not be as great compared to epigenetic factors, so therefore it seems to contradict mendelian genetics in favour of. Lysenkoism had been a prominent ideology in the ussr. The consequence was that many who advocated genetics was executed. Catastrophic crop failure and an entire generation of geneticists emigrated or died. This example shows quite clearly that the rejection of genetics has disastrous consequences on societies; one ought to follow the data. Vavilov first diagnosed that crops tend to be domesticated in areas of the greatest diversity.
