Can Evolution Explain the Diversity of Life?
Remembering the Definitions Is it possible that all of life’s diversity could be part of an unexpected, unguided process of natural selection? As we examine the claims of philosophical naturalism related to the power that evolution reportedly has to accomplish something like this, we need to begin by understanding exactly what the theory of evolution proposes. The General Theory of Evolution posits that change occurs not only ‘within’ a species, but also ‘across’ species. In this way, change is actually unlimited in the sense that, given the right circumstances and given the right environmental pressures, any form of biological life could eventually be pushed from one species to another. A lizard could be pushed into the form of a bird; a whale could be pushed into the form of a wolf.
