Do we shit the same way as the ancient human? I will give a “Nope” to that. Kathleen Meyer justified my answer with her book “How to Shit in the Woods: An Environmentally Sound Approach to a Lost Art (3rd Edition)“. The book shared interesting information on the history of pooping, hygienic method to decompose poo in the jungle, shit without a hole in jungle, how to filter water for cleaning purpose, and how to clean your buttock with the resources in the jungle. The book strongly demonstrated that our shitting behaviour has changed with the environment, infrastructure and resources we have.
