Every species can adapt to the environmental conditions in its own habitat. Every species has a certain variability coefficient peculiar to it. If we assume the highest value of this variability coefficient as 1, it may be as low as 0,01 for some species and as high as 0,9 for others.

No species has a change or variety that can pass the limit of this variability because every species encounters different stimuli in their environment almost every day and they respond to those stimuli based on their level of development and adapt to them. However, what we call variable and flexible equipment does not have a limitless property of variability; it is valid only for that species. As it is stated above, no species has the same property of flexibility and variability as another species.

We will explain adaptation to the environment a bit. Every being has three values that it shows toward every environmental factor in the habitat that it lives as maximum, minimum and optimum. Factors ...more
