Evolution & Speciation

The paradigm shift that has occurred in recent evolutionary biology is due, in large part, to a series of studies that demonstrate new species can emerge in the same populations based not only on genetics and geographic separation but also environmental factors or ecology. Many individuals, who have no problem with the concept of evolution, do take exception to a concept involving the creation of new species. Thus, speciation based on environmental factors creates an ethical dilemma for many who believe species only come into being due to God. Despite such dilemmas, ecological speciation appears here to stay based on recent studies proving environmental factors, as well as genetics and ge

eses to test the natural systems in which species dwell as a potential contributor or driving force behind speciation. For example, the number of natural predators in an ecosystem, the amount of pollution, the manner of feeding, and a host of other environmental factors are being considered as possible explanations for speciation - which at times proves quite sudden and rapid. Traditionally, it was readily and widely accepted that geographical obstacles or separation between populations of the same species would interfere with the gene flow between them. Even when each population would live in an identical ecosystem, but separated from each other, they would form random mutations that would eventually make them unable or unwilling to reproduce when they were rejoined. Because of similar research studies that demonstrate the significance of ecological factors in speciation, evolutionary biologists are now studying speciation from both a genetic and an environmental perspective. Many scientists are now convinced (due to evidence from multiple studies that geographic separation or isolation by itself is not a satisfactory answer to speciation that is rapid and requires only a few mutations to make species unwilling or unable t
