The _Times_ continues—“The position which Mr. Romanes takes up is the result of his perception shared by many evolutionists, that the theory of natural selection is not really a theory of the origin of species. . . .” What, then, becomes of Mr. Darwin’s most famous work, which was written expressly to establish natural selection as the main means of organic modification? “The new factor which Mr. Romanes suggests,” continues the _Times_, “is that at a certain stage of development of varieties in a state of nature a change takes place in their reproductive systems, rendering those which differ in some particulars mutually infertile, and thus the formation of new permanent species takes place without the swamping effect of free intercrossing. . . . How his theory can be properly termed one of selection he fails to make clear. If correct, it is a law or principle of operation rather than a process of selection. It has been objected to Mr. Romanes’ theory that it is the re-statement of a fact. This objection is less important than the lack of facts in support of the theory.” The _Times_, however, implies it as its opinion that the required facts will be forthcoming by and by, and that when they have been found Mr. Romanes’ suggestion will constitute “the most important addition to the theory of evolution since the publication of the ‘Origin of Species.’” Considering that the _Times_ has just implied the main thesis of the “Origin of Species” to be one which does not stand examination, this is rather a doubtful compliment.
