Every organism in nature evolved in sync with its ecosystem. Organisms developed special attributes and adaptations to suit their natural environment which enabled them to survive better. Hence the elements in the ecosystem and relative behavioural characteristics that beings develop over time play a vital role in its nature. Most successful natural ecosystems self-sustain by providing a balanced and mixed stimulus to the beings, which are a part of the ecosystem.
In this chapter, we consider the example of Bull. Bull was originally a wild animal.The characteristics and behaviour they developed were a result of the cycle they had in their natural environment. This natural ecosystem provided them the necessary balance and stimulus triggering and sustaining their bio-system. Due to their benefits to society, they were domesticated by Humans. Domestication provides a mutually advantageous situation for both the bulls and humans. However, losing the natural ecosystem in which bulls evolved to survive, disrupted their balanced stimulus cycle.
The situations and stimulus previously offered by the natural ecosystem are keys for the bull's healthy development and life cycle - since they originally evolved to survive there. Lack of such balanced stimulation during their growth cycle can cause detrimental effects.
It is a scientific fact that there is significant change in the psychological and physiological attributes of domesticated animals which lack the balanced natural stimulus - which they were used to in their natural habitats.
