Answer:
It ocurred a selection by allopatric speciation
Explanation:
The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.
It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.
So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.
