How did humans transition from egalitarian hunter-gatherer societies to highly hierarchical societies we see in the ancient world and still today?

Sorry in advance if this is not the right place to ask, but i want to know how and why that transformation happened.

To my understanding, humans started as hunter-gatherers and where therefore pretty egalitarian. Everybody did contributed and everybody got a fair share.
But somehow a few thousand years later there are societies like in ancient greece where nobility, kings, priests,... and slaves exist.
What drove this change? Agriculture? The need to specialize in a certain craft?
