Antonie van Leeuwenhoek Quotes
For my part, I hold it equally impossible for a small shellfish to be produced without generation as for a whale to have its origin from the mud.
Leeuwenhoek, Antony van. The Select Works of Antony van Leeuwenhoek. Translated by Samuel Hoole, vol. 2, Philanthropic Society, 1807, p. 282.
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.
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 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.
At the time, it was very difficult for people who had been taught all their lives that God was directly responsible for the creation to accept the notion of evolution. At the time, there was not the overwhelming evidence proving Darwin’s theory that we have today. Nor did theologians realize that evolution and Darwinism were not inconsistent with the concept of a creator and supreme being. Nonetheless, there are still those who, like Agassiz, reject evolution and insist that the Biblical version of creation is literally true. See {586990}. Then there are people who have come up with the concept of Intelligent Design which originated with Agassiz though he never called it that. Most religious people today, in contrast, see no conflict in natural selection as described by Darwin and later proven, and the concept of God. They see the Biblical creation as metaphorical and natural selection as the product of an omniscient supreme being.
Darwin’s work had polarized England into two camps. Spencer was one of the major public supporters of Darwin. Tennyson expressed a similar intuitive view a decade earlier {627586}. Spencer reasoned that if an egg cell and a sperm cell could produce a human in 9 months, why was it not plausible that the cell could become a human in hunreds of millions of years.
This quotation illustrates the bizarre logic used by some war enthusiasts once Darwin’s evolutionary principles received wide distribution. Kellogg explains their notion. The absurdity is that there is nothing that characterizes the soldiers who lived differentially from the soldiers who died. The survivors of a bomb if any are random or determined by position and not intellect, courage, strength or any other trait that might be used selectively. See Kellogg’s explanation {631167}.
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.
Antonie Philips van Leeuwenhoek FRS was a Dutch businessman and scientist in the Golden Age of Dutch science and technology. A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists. Van Leeuwenhoek is best known for his pioneering work in microscopy and for his contributions toward the establishment of microbiology as a scientific discipline.
