Natural Selection

“Much evidence can be adduced in favor of the theory of evolution—from biology, biogeography and paleontology, but I still think that to the unprejudiced, the fossil record of plants is in favor of special creation.”  Dr. E.J.H. Corner, Cambridge University School of Botany

“I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme—a possible framework for testable scientific theories.”  Karl Popper, philosopher of science

“Evolutionary concepts were handed down through the Greek philosophers, such as Plato and his pupil, Aristotle, all the way to Darwin’s grandfather, Erasmus Darwin (1731-1802).  Darwinism was a term first applied to the evolutionary ideas of Erasmus Darwin, a well-known physician in England.  His grandson, Charles, was quite familiar with the concepts of evolution that Erasmus Darwin [who wrote philosophy and poetry] and numerous others were discussing in the early 1800s.”  Luther D. Sunderland, Darwin’s Enigma, p. 13, 14 Continue reading

Darwin’s Finches: Unstable Ground for Evolutionary Theory

“This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being… This Being governs all things, not as the soul of the world, but as Lord over all.”  Isaac Newton

“The ground finches of the Galapagos Islands… more than anything else persuaded Darwin of the fact of evolution.”  Julian Huxley

“With Darwin’s finches selection oscillates with climatic fluctuations, and does not exhibit long-term evolutionary change.”  Jonathan Wells

“To my [Darwin’s] surprise, I learn that the evolutionary changes in the beaks of the Galapagos finches proved reversible.  When the islands experienced seasons of heavier rainfall, propagating more and smaller seed varieties for the several finch species to feed upon, the evolutionary trend in those wet years was reversed to favor individuals with more pointed beaks.  Natural selection here was an oscillating phenomenon.  While species had evidently diverged, contingent on dry-wet weather cycles, they could apparently also merge, and indeed were doing just that.  Speciation does not occur when exclusive mating behavior—the true identifier of a separate species—proves flexible.”  Nickell John Romjue, I, Charles Darwin, p. 12
