It is possible. It could relate to the properties of neutrinos, which affects
the relative masses of protons and neutrons, which affect the distribution of
elements produced by supernovas, which affect the abundance of the ingredients
of DNA and protein.
Most likely there are many sets of laws of physics that would result in life.
