and diverse topics. In more recent times the research of Peter and Rosemary Grant has shown many intriguing facts as they study the finches on the Galapagos Islands. As one
author notes, "The Grants research has improved scientists understanding of evolutionary patterns and mechanisms" (Gross, 2007). The following paper examines some of their research concerning mutation, gene frequencies, genetic drift,
and intelligent design. Peter and Rosemary Grant: Galapagos Finches The work of the Grants has studied many things ranging from coloring
to beak length in the finches. In one work, their book "Evolutionary Dynamics of a Natural Population: The Large Cactus Finch of the Galapagos," the authors illustrate how, in a
study of two kinds of males whose song was quite different, "The two groups of males differed not only in song but to a small degree in gene frequencies" (Grant;
Grant [1], 1989; 248). In essence, while the birds were, in many ways, quite similar, their findings also indicated that the frequency of one male type was more prone to
producing yellow morph hatchlings, which indicates that there are genetic differences, pointing to natural selection and the changes that occur with natural selection.
In relationship to the role of mutation in gene frequencies the authors also note that, "alleles enter a population in two ways: 1) by mutation, and 2) by introgression
of genes" which is essentially the introduction of some genetic make-up brought in by another animal or change of some kind (Grant; Grant [1], 1989; 3). Clearly, if mutation occurs
this will ultimately play a role in the genetic frequencies of a particular animal, as is evidenced in their study of finches.
