When did humans start social knowledge accumulation?

Study suggests our ancestors were building on past knowledge by 600,000 years ago.

A key aspect of humans' evolutionary success is the fact that we don't have to learn how to do things from scratch. Our societies have developed various ways—from formal education to YouTube videos—to convey what others have learned. This makes learning how to do things far easier than learning by doing, and it gives us more space to experiment; we can learn to build new things or handle tasks more efficiently, then pass information on how to do so on to others.

Some of our closer relatives, like chimps and bonobos, learn from their fellow species-members. They don't seem to engage in this iterative process of improvement—they don't, in technical terms, have a cumulative culture where new technologies are built on past knowledge. So, when did humans develop this ability?

Based on a new analysis of stone toolmaking, two researchers are arguing that the ability is relatively recent, dating to just 600,000 years ago. That's roughly the same time our ancestors and the Neanderthals went their separate ways.
