Francis Crick Quotes


Biologists must constantly keep in mind that what they see was not designed, but rather evolved.


Context

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.

The Pope went on to state that Evolution was consistent with Roman Catholic doctrine, changing a position that had been taken by the Catholic Church and many fundamental protestant denominations. A few actually still reject evolution even after all the evidence and proof of the basic Darwinian theses. There is nothing in evolution that per se denies the existence of God or even that God created the universe and the mechanism of evolution. That is why the Catholic Church and so many Protestant Churches, Judaism, Buddhists, and so many other religions have no theological problem with evolution. Those religious groups who have difficulty with evolution are those fundamentalists (Protestants, Jewish and Muslims) who believe in the literal truth of Holy Scripture. They also assume that God designed each particular plant or animal species. Other religions hold that it was God who created the mechanism of evolution and that is how all the species developed and are developing today. Some religious evolutionists believe that evolution is God’s mechanism for perfecting man.


Here the Governor makes a very common error of people who do not have scientific training. They believe that a Scientific Theory is an assertion that has not yet been proven. That is not the way scientists use the term. The Theory of Relativity, Theory of Quantum Mechanics and Theory of Evolution all scientifically refer to a major set of scientific statements and relationships that have been proven over and over again, together with many corollaries and deductions. It is an established, experimentally proven body of knowledge that is still producing additional hypotheses that then need to be proven or refuted. The scientific THEORY is as high as it gets on the scientific scale of proof. The word “theory” used in science is not one fact, but a large set of related facts and their proofs. What the Governor refers to, scientists call hypotheses or speculations. There have been many more proofs of evolution -–many thousands of them—than proofs of Relativity which is actually harder to prove and only has a few thousand proofs. More important, not one person has ever been able to prove scientifically that any of the assertions of evolution are false. Some religions have no difficulty with evolution (Roman Catholics for example) and a few do (fundamentalist Protestants for example). Governor Huckabee was also a fundamentalist Protestant minister. Even the Federal courts have held that the objections and so called “refutations” and alternatives to evolution are religious and not scientific, and hence may not be taught as science in public schools. Non evolution (like creationism) is a religious and cultural notion and should be studied as that.


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.


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.

Francis Harry Compton Crick OM FRS was a British molecular biologist, biophysicist, and neuroscientist. He, James Watson, and Rosalind Franklin played a crucial role in deciphering the helical structure of the DNA molecule. Crick and Watson's paper in Nature in 1953 laid the groundwork for understanding DNA structure and functions. Together with Maurice Wilkins, they were jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
