When two forms of Antirrhinum are crossed there is in the second generation such a profusion of different combinations of the factors in the two grandparents, that Lotsy has suggested that all variations may be due to crossing. Bateson does not agree with this.
Evolution has been merely 'the rejection of various factors from an original complex, and a reshuffling of those that were left. Professor Lotsy goes so far as to say that difference in species arose solely from crossing, that all domestic animals are of mixed stocks, and that it is easier to believe that a given race was derived from some ancestor of which all trace has been lost than that all races of fowls, for example, arose by variation from a single species, but the evidence that our varieties of pigeons have been derived from C. livia, and of fowls from G. bankiva, is too strong to be disregarded because it does not agree with theoretical conceptions.
