In paleoanthropology, the idea of behavioral modernity is associated with the belief that there are significant differences between the oldest Homo sapiens and populations younger than 50 kya. It is often defined as the point at which Homo sapiens began to demonstrate a reliance on symbolic thought and to express cultural creativity. The idea has recently come under siege and J. Shea writes: "The strongest reason for discarding 'behavioral modernity' and 'modern human behavior' is that they lack analytical precision." In the paper, he proposes that the concept be entirely replaced by the more quantitative measurement of behavioral variability. Behavioral modernity is also sometimes called the "Upper Paleolithic Revolution". In reference to this, revisionists Sally McBrearty and Alison Brooks referred to it as "the revolution that wasn't," pushing back the origins of modern behavior to the Middle Stone Age.
The difference between behaviorally modern and anatomically modern humans, or even species like Homo erectus and the Neanderthals, is a subtle one, since even 300kya modern humans in Africa were conducting trade and using pigments. The earliest known example of doodling comes from an engraving scratched onto a shell over 500kya by an unknown Homo erectus individual, and some people think that erectus invented the earliest boats and rafts.
