On the ordinary view of each species having been independently created, we gain no scientific explanation.

The very essence of instinct is that it's followed independently of reason.

Nevertheless so profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being; and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life!

It occurred to me, in 1837, that something might perhaps be made of this question (the origin of the species) by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.
