The part, known as a flaperon, was discovered on 29 July and the Malaysian authorities have said that paint colour and maintenance record matches prove it came from the missing Boeing 777 aircraft.
Prosthesis failure is caused mainly by colour change, poor maintenance, silicone tear and delamination.
In birds for example, the maintenance of colour polymorphisms may be due to differential hunting success of colour morphs due to variation in light conditions [9].
Not only are they on trend when it comes to colour, they're low maintenance, too.
You want high colour pigment and low maintenance, in which case Mac's popstar colour palette seems an easy choice.
Causes for prosthesis replacement included colour changes (71%), poor maintenance (41%), and silicone tear (37%).
Different female preferences for territorial traits, or differential investment by males in territoriality as opposed to other sexual signals might be expected to maintain genetic diversity in aggression, as has been demonstrated for maintenance of colour polymorphism in guppies [10].
The mechanisms responsible for the evolution and maintenance of colour polymorphisms in wild populations of animals have been the subject of intense research, especially in fish [2], reptiles [3] and birds [4].
Recent studies suggest a strong role for environmental heterogeneity in favouring the maintenance of colour polymorphisms [ 57- 59].
Apostatic selection, the primary hypothesis for maintenance of colour polymorphism in cryptic animals, proposes that visual predators focus on common forms of prey, resulting in higher survival of rare forms.
