Biology - Essay Example The idea of an island in the science of biology and evolution advances the idea of species evolutionary patterns. While the arguments have been made and supported for the use of fossils, and for the use of various short lived species of creatures there is still the variations of species in some areas versus others. Dawkins readily admits that he has no idea where the initial split occurred for species, however, he further clarifies by stating that given the common genetic heritage and the proliferation of biological islands separations and splits in various species is only a matter of time. Speciation is the term used by biologists to define the splitting of a species into daughter species. Creationists have adopted the idea of speciation to explain the variances that are obvious with the use of a small boat and the idea that two of every kind of animal was aboard. According to Carl Wieland of Creation.Com, â€Å"Virtually all creation theorists assume that Noah did not have with hi m pairs of dingoes, wolves and coyotes, for example, but a pair of creatures which were ancestral to all these species, and probably to a number of other present-day species representative of the ‘dog kind’.† (Wieland) Unfortunately, creationists still rely on a much shorter time period which cannot explain the lengths of time needed for each major shift and even for the minor shifts in various dog breeds and canine sub species.
