will never produce in a being anything injurious to itself, for natural selection acts solely by and for the good of each. 1859 1860 1861

→ And we see that this is the degree of perfection attained under nature. 1866

No organ will be formed, as Paley has remarked, for the purpose of causing pain or for doing an injury to its possessor. 1859 1860 1861

→ The endemic productions of New Zealand, for instance, are perfect one compared with another; but they are now rapidly yielding before the advancing legions of plants and animals introduced from Europe. 1866

If a fair balance be struck between the good and evil caused by each part, each will be found on the whole advantageous. 1859 1860 1861

After the lapse of time, under changing conditions of life, if any part comes to be injurious, it will be modified; or if it be not so, the being will become extinct, as myriads have become extinct.
