Whenever you watch documentaries a lot of them show our oldest ancestors like Australopithecus sleeping on the ground and I've read a couple articles that talk about how but I recently read that basically all apes build nests in trees. I also know that hunter gatherers built huts out of things like sticks and animal skins. Which is the correct portrayal? Was this something that has always been with humans and other ancestral apes or is it something that only developed relatively recently alongside modern humans? Wikipedia states "Early hominins did not construct structures but rather chose caves and other shelters in which to live. The emergence of built structures occurred gradually over time with the earliest structures functioning as wind breaks rather than covered huts." But fails to provide a timeline or much other information.
