Sure—a full-scale nuclear war that collapsed civilization and technology but didn’t actually kill every living human would count.
In terms of less grandiose things, if the actual lived experience of being a human changed dramatically with the the invention of important and novel emotions or social structures, I would consider that a fundamental change. Some argue that this actually happened during the medieval period and that romantic love didn’t exist before then, but I’m highly skeptical of this claim for multiple reasons.

Those two items seem to me to completely fill their classes of comparables, so there is no ‘cetera’.
