Uncommon Descent Serving The Intelligent Design Community

Humans 200,000 years ago made beds of ash and grass


The ash layer underneath probably deterred insects:

A cave in South Africa may hold early evidence of human innovation in sleep technology. A new paper published today shows how people 200,000 years ago put together grass and ash to make carpet-like structures to keep insects off them while they slept. The use of ash suggests they could control fire.

Lyn Wadley, an archaeologist at the University of the Witwatersrand in Johannesburg, South Africa, had worked at a different cave previously. There, she discovered 77,000-year-old bedding made from grass-like plants called sedges. “The sedges had medicinal plants on them, presumably laid there to serve as an insect deterrent,” Wadley wrote in an email. “I was fascinated by the idea that early Homo sapiens would have had such knowledge.”Katharine Gammon, “200,000 Years Ago, Humans Created Beds of Grass and Ash to Sleep” at Inside Science

Some of the ash at Border Cave was from camphor wood, a medicinal herb.

They must have known how to control fire if they had easy access to ash. Like the Neanderthals, they get smarter with each cycle of papers.

I always associated camphor with mothballs, but it turns out to be pretty much a universal medicine. Fights all kinds of microbes as well as insects and pain. An excellent article, with a mix of science and poetry... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6270224/ Needless to say, most of the info on the web gives the opposite advice, treating camphor as EMERGENCY DEADLY POISON CALL 911. We've turned everything upside-down. Science is murder. polistra
