The human being from remote times has admired the capacity of flight that have so
me animals, is for this reason that with the help of the technology has managed to fly. However, he continues studying as the flying animals manage to dominate the physical and metabolic challenges of the flight.
Physiological adaptations exist, in the animals, that allow to overcome certain specific deficiencies. Example of this is that in the animals that fly they face deficiencies in the flight in relation to its size; if they are very small or very big. The smallest animals must flutter more rapidly their wings to manage to overcome the resistance of the air. Whereas that the animals of greater size need more energy to realize their flight, as also they have difficulty in the distribution of the oxygen and sugars.
The phenomenon of hovering is another factor to considering, since it is energy-demanding, because it must be sustained for long time, reason why to needs of great quantity of energy.
The hummingbirds have great capacity of hovering, reason for that to consume around five times their body weight in energy. They arrive at big heights because the hummingbirds have morphologic and physiological adaptations. Of these adaptations the main are its wings, this confer aerodynamic advantages that to allow to save energy, to reduce drag and to increase lift, besides allowing the insulation.
On the other hand, the bats are considered to be rather second-rate flyers because they do not have great capacity of hovering as birds or insects. Nevertheless, they have special ability in the acrobatic. These acrobatic movements allow to take insects in the air for which it adapts the form of its wings.
In spite of the great adaptations that present the birds and the bats, has been observed that in the insects the flight has developed deeper genetic adaptations.

Two forms of flight exist, that are different in the relation between the nervous system and the wings. The more "primitive" form of flight is the synchronous flight used by birds, bats and insects of major size. In insects of minor size, as bumblebees, it does not work because it is not possible to realize contractions of the muscle so rapidly. Therefore some insects developed a different mechanism; the asynchronous flight. In case of this mechanism the nervous system communicates with "flight engine" that to controls the muscles of the flight.
Exist varied physiological adaptations at muscular level for this type of flight, like for example a protein called flightin that gives the stiffness it myofibrils of the muscle to make rapid wing, without losing elasticity.
Has been demonstrated that some insects have special mechanisms related to the size and wing beat frequency. In the case of the honeybee, this adaptation allows the transport of loads.
Although the investigations above the flight have been able to answer many questions, while the dream of flight exists in the human, will arise new questions that to solve.
