The Environment does not Control Morel Variations. The Environment does not Control Morel Variations. There are qualitative differences in the variations of morels. The environment cannot create qualitative effects.
Examples are in pigmentation, shape and tissue thickness.
These properties result from complex physiology which leaves no room for environmental influences. All of the characteristics of any biological organism are controlled through extremely demanding physiology. The mechanisms of control are so complex and thorough that no room is left for environmental influences. Two billion years of biological evolution was directed toward overcoming the effects of the environment. The result is thorough control through physiology of all characteristics of biological organisms.
