If the Sun were replaced by one solar mass black hole, we would freeze/starve to death but the Earth's orbit would be just as stable as it is now.
In fact Earth might survive (as an ice planet) much longer than it would around the Sun since the Sun is expected to become a red giant and possibly swallow the Earth when it dies.

And as a motivator for both our intellectual curiosity and our scientific curiosity, the lack of a detailed moon in our night sky would have retarded the development of human civilization.
