During the Paleolithic era, there was more than one species related to the modern human, including Neanderthals. They lived a nomadic lifestyle as hunter-gatherers, not settling in any permanent communities and with no concept of private property. They used pretty simple stone tools.
During the Neolithic era, there was only one species of human—the modern human. They started domesticating plants and animals, developing agriculture, and settling into permanent communities. This was the beginning of permanent architecture. Humans also developed or improved skills like spinning, weaving, and pottery. Wall paintings, which started in this era, are less durable than cave paintings, and very few survive. It’s perhaps because of this that this era is more known for crafts and architecture than painting.
