What Evidence of Evolution Do Darwins Finches Provide?
In May 2003 I had my first opportunity to visit the Galapagos Islands with a group led by several scientists from the Institute of Creation Research. Our goal was simply to see for ourselves many of the unusual animals and plants which so heavily influenced Darwin in the development of his theory of natural selection. Look in almost any high school biology textbook and you will find some mention, if not a whole section, on what are now known as Darwin’s finches. Darwin’s finches are comprised of thirteen different species of small finches that arose from a single species that colonized the islands. The finches have adapted to differing food sources ranging from different size seeds, to insects, to cactus flowers, to even blood. The major feature of these finches that has changed is the size and shape of their beaks, but the differences are very subtle. When we got our first glimpse of the finches we found out just how subtle the differences in beak size and shape really are. Without be
