But to extend it so far as to suppose that species, aboriginally as distinct as carriers, tumblers, pouters, and fantails now are, should yield offspring perfectly fertile, inter se, seems to me rash in the extreme.
Baina hau honako hau esateraino hedatzea, hots, mezulariak, itzulipurdikariak, papohandiak eta fantail-ak egun diren bezalako espezie jatorriz hain ezberdinek, inter se erabat ernalkorrak diren ondorengoak sortu behar dituztela, gehiegizko ausarkeria litzateke.
