Africa's Homo Sapiens Were the First Techies
enlarge
ScienceDaily (Dec. 5, 2012) The search for the origin of modern human
behaviour and technological advancement among our ancestors in southern Africa
some 70,000 years ago has taken a step closer to firmly establishing Africa,
and especially South Africa, as the primary centre for the early development of
human behaviour.
A new research paper by Wits University archaeologist, Prof. Christopher
Henshilwood, is the first detailed summary of the time periods he and a group
of international researchers have been studying in South Africa: namely the
Still Bay techno-traditions (c. 75,000 -- 70,000 years) and the Howiesons Poort
techno-tradition (c. 65,000 -- 60,000 years).
The paper, entitled "Late Pleistocene Techno-traditions in Southern Africa: A
Review of the Still Bay and Howiesons Poort, c. 75 ka," has been published
online in the Journal of World Prehistory on Nov. 6, 2012.
Henshilwood says these periods were significant in the development of Homo
sapiens behaviour in southern Africa. They 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; 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 launched by bow.
"All of these innovations, plus many others we are just discovering, clearly
show that Homo sapiens in southern Africa at that time were cognitively modern
and behaving in many ways like ourselves. It is a good reason to be proud of
our earliest, common ancestors who lived and evolved in South Africa and who
later spread out into the rest of the world after about 60,000 years," says
Henshilwood.
The research also addresses some of the nagging questions as to what drove our
ancestors to develop these innovative technologies. According to 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 Henshilwood and his teams' research
on African archaeology that revolutionised 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.
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."
