2. The first question presenting itself is this: has each animal species sprung from a single first couple, or have many couples been created simultaneously in different places?
This last supposition is the most probable. One can even call it a result of observation. Accordingly, studies of the geological layers indicate the presence of the same species in great quantities — in terrains of identical formation — on points of the globe very distant from one another. Such generalized and somewhat contemporaneous multiplication would have been impossible with one single primitive type.
Moreover, the life of an individual, above all that of a growing child, is submitted to so many uncertainties, that an entire species would be endangered without a plurality of primitive types, which would not be in accordance with divine foresight. Besides, if one type has been able to form itself upon a certain point, there is no reason why it should not be formed in many places by the same cause.
All concur then in proving that there has been a simultaneous and multiple creation of the first couples of each animal and vegetable species.
