Plus there is no analysis as to whether the crocs posessed the adaptation from previous experience and it was maintained as a recessive passive trait. Remember that the environment changes are functuations and not permenet. An adaptation to a historical tendency of the environment to vary is a slow adaptation that occurs in spurts of reduction of the non-adapted genotype.
