The researchers don’t know which ancient human species made the structure and the tools, but it’s unlikely to have been Homo sapiens. The earliest fossils of Homo sapiens found so far date from around 300,000 years ago and were found in Israel, Dull told CNN. He believes the people who made the structure were cognitively sophisticated and it would be very exciting to figure out who constructed this.

Truly astonishing that hominids had the instinct to build couch cushion forts long before couches, cushions, or forts were even invented.

Instinct?

And if they built couch cushion forts, then they invented the couch, the cushions and the forts.

Truly nature is healing. Ecosystems are now abundant with couches and cushions where none existed before. It’s a return to environmental normalcy.
