Professor Henshilwood's paper is the first detailed summary of research into the Still Bay techno-traditions, dating back 75,000 years, and the Howiesons Poort techno-tradition, which dates back 65,000 years.
The paper, entitled Late Pleistocene Techno-traditions in Southern Africa: A Review of the Still Bay and Howiesons Poort, c. 75 ka, published online today in the Journal of World Prehistory.
These were periods of many innovations including, for example, the first abstract art (engraved ochre and engraved ostrich eggshell); the first jewellery (shell beads); the first bone tools; and the earliest use of the pressure flaking technique, that was used in combination with heating to make stone spear points and the first probable use of stone tipped arrows.
The research also addresses some of the nagging questions as to what drove our ancestors to develop these innovative technologies.
According to Professor Henshilwood answers to these questions are, in part, found in demography and climate change, particularly changing sea levels, which were major drivers of innovation and variability in material culture.
This paper is just the latest to come from Professor Henshilwood and others' research on African archaeology that has debunked the idea that modern human behaviour originated in Europe after about 40,000 years ago
There is increasing evidence for an African origin for behavioural and technological modernity more than 70,000 years ago and that the earliest origin of all Homo sapiens lies in Africa with a special focus in southern Africa.
Last month MailOnline reported a new study by U.S. researchers which suggested the development of 'high tech' long range weapons 71,000 years ago in the region gave humans the killing edge to help make us the dominant species.
The findings at Pinnacle Point, near Mossel Bay, included Stone Age technology that only took hold in other areas of Africa and in Eurasia about 50,000 years later.
Those researchers noted that the depth of archaeological research in Africa was minuscule compared to that which has taken place so far in Europe, and because of that it was likely that far more would be learned soon.
In the new paper, Professor Henshilwood writes: 'In just the past decade our knowledge of Homo sapiens behaviour in the Middle Stone Age, and in particular of the Still Bay and Howiesons Poort, has expanded considerably. 'With the benefit of hindsight we may ironically conclude that the origins of "Neanthropic Man", the epitome of behavioural modernity in Europe, lay after all in Africa.'
