Peter Louis Moreau de Maupertuis Quotes
The elementary particles which form the embryo are each drawn from the corresponding structure in the parent, and conserve a sort of remembrance of their previous form, so that in the offspring they will reflect and reproduce a resemblance to the parents ... We can thus readily explain how new species are formed... by supposing that the elementary particles may not always retain the order which they present in the parents, but may fortuitously produce differences, which, multiplying and accumulating, have resulted in the infinite variety of species which we see at the present time.
As early as this was in scientific history, he essentially described the process whereby new species are formed by the mutation from the old series.

See Charles Darwin for the later elaboration of notions of man's evolution. As this quotation shows, scientists other than Darwin had suspected the process of evolution even before. See also {590323}.
Darwin did not develop an interest in the origin of life in a vacuum. His grandfather and many other scientists and naturalists had realized that species evolved and improved over tome and generations. What Charles Darwin added was the principles of the mechanism of how it all worked.
This quotation from this letter was one of the key items of evidence showing that Wallace had independently developed the concept of Evolution before Darwin published his famous treatise. Darwin began formulating his theory of natural selection in the late 1830s but he went on working quietly on it for twenty years. He wanted to amass a wealth of evidence before publicly presenting his idea. During those years he corresponded briefly with Wallace (right), who was exploring the wildlife of South America and Asia. Wallace supplied Darwin with birds for his studies and decided to seek Darwin's help in publishing his own ideas on evolution. He sent Darwin his theory in 1858, which, to Darwin's shock, nearly replicated Darwin's own…. Joseph Dalton Hooker arranged for both Darwin's and Wallace's theories to be presented to a meeting of the Linnaean Society in 1858. However, Wallace seems to have been onto the idea of evolution over a decade before as this quotation shows.
The Bible contains two separate and somewhat contradictory versions of creation (Adam & Eve vs. the 6 day creation).
Evolution sometimes produce or retain components that have no purpose or are even inefficient. But he is urging the biologist to remember that none of the life form were designed much less designed efficiently. We humans have an appendix for example, which does nothing positive and sometimes gets infected and kills us. Yet it is still there. We have so much else on the positive side that a few weaknesses are not material to our survival.
This is a very important quotation in the history of science. Note that he has the concept of evolution and mutation before Darwin published his his Origin of Species. Darwin had probably come to these conclusions at the time that Lawrence gave this lecture. And of course Darwin had a much broader concept and much data to back it up. But this was one of the great insights in science.
