In South Africa, researchers have discovered a 100,000-year-old workshop that may have been used by early Homo sapiens to make, mix, and store ochre—the earliest form of paint.

The use of ochre, which is essentially just colorful dirt, has been well-documented after about 60,000 years ago. But these new findings show that early humans were using ochre much earlier than that, as well as producing and storing it.
