I'm sharing a BBC Nature documentary that I watched last night, titled The Animal House, and at the risk of autoplay hell I will only post a link here:
As a person who watches some kind of documentary every night on YouTube as a sleep-inducing panacea, this film kept me awake for the duration. Most astonishing was the scientist who pumped concrete through an abandoned ant colony and then excavated once dry. Even more odd was that humans are the only primates that actually build shelters for themselves, while the simplest creatures can build elaborate homes.
Enjoy if you care to watch!
