    Sea levels rise and fall in response to complex planetary drivers, including shifts in polar ice caps, land masses, and other factors. Understanding these processes is crucial for studying prehistory in deep time, including human migration from Sundaland to Sahul and the movement of people around the globe. In this episode, Justin Dix breaks down what drives sea level change, how scientists reconstruct past sea levels, and how these fluctuations have shaped human history.
