I'm not sure what you mean by "invention of the domicile." A domicile is a home. People have always had homes. Do you mean a permanent structure, as opposed to a tree nest such as a chimpanzee would construct, a time when our ancestor primates came down from the trees and started to live in caves, or build huts or multi-generational longhouses?Thank you for posting this. And I really do mean this and I promise you that I am not taking the piss out of you.
This series of questions that you raised has had me looking various things up online this weekend as I know next to nothing in regards to how we lived as humans prior to the invention of the domicile. It's been very interesting research and I have quite enjoyed researching this topic.
