Peter R. Grant Quotes


Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are subject to natural and sexual selection.

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.


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.

Peter Raymond Grant, FRS FRSC and Barbara Rosemary Grant FRS FRSC (born October 8, 1936) are a British married couple who are evolutionary biologists at Princeton University. Each currently holds the position of emeritus professor. They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of years. Charles Darwin originally thought that natural selection was a long, drawn out process. The Grants have shown that these changes in populations can happen very quickly.
