But Just In Proportion As This Process Of Extermination Has Acted On An Enormous Scale, So Must The Number Of Intermediate Varieties, Which Have Formerly Existed, Be Truly Enormous. Why Then Is Not Every Geological Formation And Every Stratum Full Of Such Intermediate Links? Geology Assuredly Does Not Reveal Any Such Finely Graduated Organic Chain; And This, Perhaps, Is The Most Obvious And Serious Objection Which Can Be Urged Against The Theory. The Explanation Lies, As I Believe, In The Extreme Imperfection Of The Geological Record.
