Complete 5 pages APA formatted article: The Evolution of Flight in Birds. The proponents of the ground-to-up theory of evolution of flight in birds hold that the wings were first applied to catch insects and not primarily for flying, thus it is in the process of trying to use wings to reach the insects upwards, that the flight tendencies developed, and finally the birds were able to fly (Speakman, 2001). While each of the above theory seems to hold some ground, it makes the understanding of evolution of flight in birds so elusive, such that there is no telling what to believe anymore. Nevertheless, these are just mere believes that have not been backed by any scientific data or evidence, thus remains just theoretical explanations of the evolution of flight in birds, requiring that more scientific and well-grounded explanations should be developed.The major issue that brings the complexity of the explanation of the evolution of flight in birds, is the issue of why, considering the fact that evolution is a field that does not deal with the question why, only concerning itself with what is and how it might have come about, but not for what reasons (Schluter, 2001). Therefore, the first step to reaching a conclusion on how the evolution of flight in birds came about must start with their ancestral origin or lineages as explained by the theory of evolution (Burgers & Chiappe, 1999). The theory of evolution holds that the ancestors of the flying animals must have been the glider. the arboreal glider that is characteristic of the modern ones that are non-aquatic, to mean that flight must have then evolved from an arboreal ancestor (Noberg, 2002).Nevertheless, without wings, there can be no flight. Thus, the first question that needs to be answered, while addressing the issue of the evolution of flight in birds, is the concept of wings and wings development. .
