In the life sciences it is typical to see limitations placed on the application of laws. For example, Mendel’s laws of inheritance work only with single gene pairs and not even with all such pairs. This issue has called some to question if there are really laws in biology. My response would be that there are laws in the life sciences, but the rules for their application are somewhat distinct from those applied in the physical sciences.

Another approach would be to abandon the word hypothesis in favor of terms such as speculative law or speculative theory.
