Only The Fittest Will Survive.

I Am Actually Weary Of Telling People That I Do Not Pretend To Adduce [direct] Evidence Of One Species Changing Into Another, But I Believe That This View Is In The Main Correct, Because So Many Phenomena Can Thus Be Grouped End Explained.

As The Sense Of Smell Is So Intimately Connected With That Of Taste, It Is Not Surprising That An Excessively Bad Odour Should Excite Wretching Or Vomitting In Some Persons.

Animals Manifestly Enjoy Excitement, And Suffer From Annul And May Exhibit Curiosity.

I Think It Inevitably Follows, That As New Species In The Course Of Time Are Formed Through Natural Selection, Others Will Become Rarer And Rarer, And Finally Extinct. The Forms Which Stand In Closest Competition With Those Undergoing Modification And Improvement Will Naturally Suffer Most.

Any One Whose Disposition Leads Him To Attach More Weight To Unexplained Difficulties Than To The Explanation Of Facts Will Certainly Reject My Theory.
