This paper show direct relation between the shape adopted the species and his environmental where it development his life cycle. When the environmental require specially condition, the organism must to answer to it with a morphology adaptive and this adaptation can to be functional, morphological and reproductive too. The answers more fast and efficient like to be the morphology and this last one carry an answer physiology too, because the organ do the function. So the whole (morphology + function) playing a fundamental role for some species must to be development in environmental with multiples variation and lack of equilibrium. Here show some cases about it.
