Worms Have Played A More Important Part

The Noble Science Of Geology Loses Glory From The Extreme Imperfection Of The Record. The Crust Of The Earth With Its Embedded Remains Must Not Be Looked At As A Well-filled Museum, But As A Poor Collection Made At Hazard And At Rare Intervals.

The Main Conclusion Here Arrived At ... Is That Man Is Descended From Some Less Highly Organized Form.

I Am Aware That The Conclusions Arrived At In This Work Will Be Denounced By Some As Highly Irreligious; But He Who Denounces Them Is Bound To Show Why It Is More Irreligious To Explain The Origin Of Man As A Distinct Species By Descent From Some Lower From, Through The Laws Of Variation And Natural Selection, Than To Explain The Birth Of The Individual Through The Laws Of Ordinary Reproduction. The Birth Both Of The Species And Of The Individual Are Equally Parts Of That Grand Sequence Of Events, Which Our Minds Refuse To Accept As The Result Of Blind Chance.

A Cell Is A Complex Structure, With Its Investing Membrane, Nucleus, And Nucleolus.

For I Am Well Aware That Scarcely A Single Point Is Discussed In This Volume On Which Facts Cannot Be Adduced, Often Apparently Leading To Conclusions Directly Opposite To Those At Which I Have Arrived. A Fair Result Can Be Obtained Only By Fully Stating And Balancing The Facts And Arguments On Both Sides Of Each Question.
