But is this scientific evidence? As to the 1st, the Bishop only claims for it that it “_seems_ to point.” As to the 2nd, it quietly assumes the whole point at issue, for no one denies that there are variations “within each class or group,” and the fact that such variations exist within a certain class or group is no proof that they can extend beyond it. And as for the 3rd who knows that those that are called “useless parts” are really useless, though their use may not be known? And if they are useless now, what evidence is there that they were once useful, or were ever used? There is not the slightest scientific evidence in any one of these three points for the theory which they are adduced to support. There is not a single fact to prove the theory, and all that can be said by the most ardent advocate is that the conjecture seems to be probable. But how different is the evidence on the other side of the controversy! There we find certain clearly-defined and indisputable facts which cannot be doubted, and which cannot be reconciled with this new theory. (1) _Biological Evolution_. There cannot be a doubt that there are certain great classes of plants and animals found in the world, which have certain distinct characteristics, and which, as a matter of fact, do not merge into each other. There seems to be considerable variation in the names given to them, and they appear to be distinguished by the name sometimes of “species,” sometimes of “genus,” sometimes of “class or group,” and sometimes of “kind.” In the sentence quoted from Darwin on p. 6, he speaks of species, genera, and families; and describes them as being all descended each within its own class or group. This confusion of terms is difficult to reconcile with the boasted claim to scientific accuracy. That I may not be entangled by any questionable name I will distinguish these groups as A, B, C, D, etc., and our question is whether they have been evolved from each other or through each other, from a common stock; or whether they are separate creations. For the answer to this question let three facts be carefully considered.
