Can humidity in subfloor cause overwood? Or is it installation issues?

Q: Can humidity in subfloor cause overwood? Or is it installation issues? I have several examples in my newly installed floor, plus several cracked boards.

The contractor is blaming subfloor/basement humidity (floor is on first level above the basement), but I think it is a bad installation.

RH and moisture readings before installation

Q: I installed hardwood flooring on the main level and the top level of a new home as well as a hardwood staircase. The install was in Nov 2013. The floor on the main level is showing areas of gaping and splitting and so is the staircase. There is a lot of shrinkage in the trim and mouldings as well as some shrinkage in the kitchen cabinets and the solid wood cupboard doors in the same areas of the house.
