Summary
It will have been seen that in the preceding pages the theory of evolution, as originally propounded by Lamarck, has been more than once supported, as against the later theory concerning it put forward by Mr. Darwin, and now generally accepted.
It is not possible for me, within the limits at my command, to do anything like justice to the arguments that may be brought forward in favour of either of these two theories. Mr. Darwin's books are at the command of every one; and so much has been discovered since Lamarck's day, that if he were living now, he would probably state his case very differently; I shall therefore content myself with a few brief remarks, which will hardly, however, aspire to the dignity of argument.
According to Mr. Darwin, differentiations of structure and instinct have mainly come about through the accumulation of small, fortuitous variations without intelligence or desire upon the part of the creature varying; modification, however, through desire and sense of need, is not denied entirely, inasmuch as considerable effect is ascribed by Mr. Darwin to use and disuse, which involves, as has been already said, the modification of a structure in accordance with the wishes of its possessor.
According to Lamarck, genera and species have been evolved, in the main, by exactly the same process as that by which human inventions and civilisations are now progressing; and this involves that intelligence, ingenuity, heroism, and all the elements of romance, should have had the main share in the development of every herb and living creature around us.
