This is known as the anthropic principle. In some sense these laws are 
not special. But in another sense, they are special in the way that they 
allowed intelligent life to form to discover those laws. In another 
universe, perhaps, the laws are different enough that there would be no 
intelligent life to discover them.

There's a couple of thoughts here. One is that there are constants in 
nature that are not determined by a law but have to be empirically 
measured. Planck's constant is an example. There have been hypotheses 
that ask what the implications would be if one or more of these 
empirical constants changed over time.

Another thought is pretty well known, called spontaneous symmetry 
breaking. This is the apparent loss of a symmetry at a lower energy 
scale that prevailed at a higher energy. One solid example of this is 
weak and electromagnetic interactions. Everything we see about them at 
ordinary energy scales says these are two completely distinct 
fundamental forces. But it's been shown that these are extremely likely 
to be just facets of one electroweak interaction, where at higher 
energies, the two are indistinguishable. So in this sense, the laws of 
physics changed in a subtle way at the energy of spontaneous symmetry 
breaking.
