Nothing Can Be More Improving

And Hail Their Queen, Fair Regent Of The Night.

The Lower Animals, On The Other Hand, Must Have Their Bodily Structure Modified In Order To Survive Under Greatly Changed Conditions. They Must Be Rendered Stronger, Or Acquire More Effective Teeth Or Claws, In Order To Defend Themselves From New Enemies; Or They Must Be Reduced In Size So As To Escape Detection And Danger. When They Migrate Into A Colder Climate They Must Become Clothed With Thicker Fur, Or Have Their Constitutions Altered. If They Fail To Be Thus Modified, They Will Cease To Exist.

As Natural Selection Acts By Competition, It Adapts The Inhabitants Of Each Country Only In Relation To The Degree Of Perfection Of Their Associates; So That We Need Feel No Surprise At The Inhabitants Of Any One Country, Although On The Ordinary View Supposed To Have Been Specially Created And Adapted For That Country, Being Beaten And Supplanted By The Naturalised Productions From Another Land.

On The Theory Of Natural Selection We Can Clearly Understand The Full Meaning Of That Old Canon In Natural History, “natura Non Facit Saltum.” This Canon, If We Look Only To The Present Inhabitants Of The World, Is Not Strictly Correct, But If We Include All Those Of Past Times, It Must By My Theory Be Strictly True.
