“A tidy house, a tidy mind.” Some of the more slovenly among us might bristle at this scolding old proverb, but to human evolution researchers it makes perfect sense. One of the hallmarks of modern behavior is the sophisticated way Homo sapiens organizes the spaces it lives in, with everything in its place. But new work at a nearly 800,000-year-old hominin site in Israel suggests that the roots of tidiness may lie deep in our evolutionary past.
Prehistoric humans did not start building permanent dwellings until about 15,000 years ago, but earlier …

In a stone-age version of “Iron Chef,” early humans were dividing their living spaces into kitchens and work areas much earlier than previously thought, a new study found.
So rather than cooking and eating in the same area where they snoozed, early humans demarcated such living quarters.
Archaeologists discovered evidence of this coordinated living at a hominid site at Gesher Benot Ya‘aqov, Israel from about 800,000 years ago. Scientists aren’t sure exactly who lived there, but it predates the appearance of modern humans, so it was likely a human ancestor such as Homo erectus.
