Thus, the existence of a hypothesis is an important condition for scientific research. Hypothesis is a link between present and future of knowledge, it is a paving stone of bridge of science.

In order to test a claim scientifically, it must be possible that the claim could also be proven false. One of the hallmarks of a pseudoscience is that it makes claims that cannot be refuted or proven false.
We hypothesize that the beavers in this study will choose trees that are small in circumference and closest to the water. Since the energy yield of tree species may vary significantly, we also hypothesize that beavers will show a preference for some species of trees over others regardless of circumference size or distance from the central area. ( Statement of hypotheses) The optimal foraging theory and central place theory lead us to predict that beavers, like most herbivores, will maximize their net rate of energy intake per unit time. In order to maximize energy, beavers will choose trees that are closest to their central place (the water) and require the least retrieval cost. Since beavers are trying to maximize energy, we hypothesized that they will tend to select some species of trees over others on the basis of nutritional value.
