. Excavations since the year 2000 of a series of caves at Pinnacle Point have revealed occupation by Middle Stone Age
Middle Stone Age
The Middle Stone Age was a period of African Prehistory between Early Stone Age and Late Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50-25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550-500,000...

 people between 170,000 and 40,000 years ago. The focus of excavations has been at Cave 13B (PP13B), where the earliest evidence for the systematic exploitation of marine resources (shellfish) and symbolic behavior have been documented, and at Pinnacle Point Cave 5-6 (PP5-6), where the oldest evidence for the heat treatment of rock to make stone tools has been documented. The only human remains have been recovered from younger deposits at PP13B which are ≈100,000 years old.

History of the research

The discoveries at Pinnacle Point have been made by an international team, headed by palaeoanthropologist Curtis Marean from the Institute of Human Origins of the Arizona State University

Pinnacle Point 13B and its implications for modern behaviour

At PP13B the evidence for symbolic behavior comes in the form of scrapped and ground ochre
Ochre
Ochre is the term for both a golden-yellow or light yellow brown color and for a form of earth pigment which produces the color. The pigment can also be used to create a reddish tint known as "red ochre". The more rarely used terms "purple ochre" and "brown ochre" also exist for variant hues...

A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light.Many materials selectively absorb...

Blombos Cave
Blombos Cave is a cave in a calcarenite limestone cliff on the Southern Cape coast in South Africa. It is an archaeological site made famous by the discovery of 75,000-year-old pieces of ochre engraved with abstract designs and beads made from Nassarius shells, and c. 80,000-year-old bone tools...

 slightly further to the west at roughly 70,000 years ago. These discoveries contradicts the classical hypothesis that the modern behaviour emerged only 40,000 years ago and was reached through a "large cultural leap". The harsh climate and reduced food resources may have been why people moved to the shore at Pinnacle Point, where they could eat marine creatures like shellfish, whale, and seal.
