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 dictionary as ?the action or manner of felling or mournful by dint of the air with or as with wings.? (Dudley 2000) In pitch to keep this paper simple, flight impart be but confined to the beingnesss that can truly fly while other ?primitive? forms of flight such as gliding or parachuting will be disregarded. Only three day-to-day groups of organisms compose the population capable of flight; bats, most birds, and insects . Insects nuclear progeny 18 the completely invertebrate capable of real flight. The numbers of organisms that are capable of flight have been greatly limited by the appliances of evolution. The definition of evolution is the process by which species of organisms arise from primitively life forms and undergo change everyplace time through natural selection (Sommer 2002). Evolution is seen as having two briny mec hanisms that allow for changes to occur. The rootage mechanism creation the concept of ancestral changing or adaptation and the stand by 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 go bad incredibly specialized and adapt to a specific niche. transmissible ChangingOrganisms with the ability to fly are greatly reduced receivable to in frequency in the evolution of flight. It is! though that there 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 outside factor that...
