 This resulted in southwestern species to evolve and specialize separately, giving rise higher to the higher level of endemism that can be seen today.Some of the mountain peaks of the central highlands reach above 2500 m, although the average height is 1800 m. Knuckles rises to 1800 m, with an average elevation of 1500 m. Because of the elevation, ambient temperature is cooler than in the lowlands.The mean temperature in this area ranges between 15 °C-20 °C.
