& Europe, as to produce same one. Although in plants, you cannot say that instinct perverted, yet organization especially connected with generation certainly is. =

The dislike of two species to each other is evidently an instinct — & this prevents breeding, now domestication depends on perversion of instinct (in plants domestication on perversion of structures especially reproductive organs) & therefore the one distinction of species would fail. But this applies only to coition & not production. But who can say, whether offspring does not depend on mind or instinct of parent.
