The infrequency of flight from an evolutionary perspective

IntroductionFlight is considered to many as a specialized and r be solve of locomotion. Flight is defined by the Oxford English lexicon as ?the action or manner of felling or miserable by dint of the air with or as with wings.? (Dudley 2000) In methodicalness to keep this paper simple, flight impart be alone confined to the existences that can truly fly while other than ?primitive? forms of flight such as gliding or parachuting will be disregarded. Only three routine groups of organisms compose the population capable of flight; bats, most birds, and insects . Insects atomic progeny 18 the yet invertebrate capable of aline flight. The numbers of organisms that are capable of flight have been greatly limited by the tools of evolution. The definition of evolution is the process by which species of organisms arise from primitively life forms and undergo change oer time through natural selection (Sommer 2002). Evolution is seen as having two briny mechanisms th at allow for changes to occur. The early mechanism world the concept of ancestral changing or adaptation and the sanction is natural selection. The number of flying species is limited by the first mechanism delinquent to the low probability that an organism will evolve and play the physiological requirements for flight (Dudley 2000).

The second mechanism limits flight because, receivable to the limitation of food sources, organisms must produce incredibly specialized and adapt to a specific niche. hereditary ChangingOrganisms with the ability to fly are greatly reduced receivable to infrequency in the evolution of flight. It is though that ther! e has only been four dissimilar time periods in which flying organism were introduced (Dudley 2000). The first being insects and the last being bats. These traits for flying were introduced by a species or a group of species. These organisms were exposed to an immaterial factor that...
