Dear Dr. Mayr:
Many thanks for your kind letter of Nov. 7th, which is so highly flattering to me, and to which I certainly want to reply.
The need for a reconciliation of the views of taxonomists and geneticists I feel very keenly, but it seems to me that all what is to be reconciled are just the viewpoints, since I do not perceive any contradictions between the facts secured in the respective fields. Of course, this is a big “just”. So far, geneticists appear to think that they need not pay any attention to what taxonomists are doing, and vice versa. To my mind this is the root of the trouble. Probably no less than 75% of geneticists still believe that there is nothing in particular to be gained from studies on the races of wild animals as compared with races in bottles. You and myself will probably have no disagreement as to the absurdity of this view.
Sincerely yours, Th. Dobzhansky.
