This volume is a result of a conference that was held at Bristol University
in April 2000 to explore the current state of research into human evolution
from an African and Asian perspective. The volume, paralleling the focus
of the conference nails its colours to its mast early on. It reflects
the research interests of the principle academics in CHERUB (Centre
for Human Evolutionary Research at the University of Bristol), namely
Lawrence Barham (Africa) and Kate Robson-Brown (Asia). The conference
launched CHERUB, and this book is a fitting tribute to the success of
both. The narrow geographical focus of its contributors was shadowed
by a strong representation of 'Out of Africanists', the contributions
to the volume therefore assume a recent origin for Modern Humans. In
retrospect a few European papers would not have gone amiss, nor detracted
from the interest of the volume. I am sure that Mark Robert's lecture
on European Palaeolithic delivered one evening in Bristol Zoo would
have added a further element of comparative interest (although what
more long term residents must have made of his hunting hypotheses is
anybody's guess). Another agenda lurks close to the surface. The editors
are at pains to point out that the last major international conference
on the Middle Pleistocene was the 1973 Burg-Wartenstein (Austria) meeting
that launched the volume After the Australopithecines. The picture of
the Middle Pleistocene world painted then is very different from that
in these pages. The volume does not contain contributions by all the
speakers, which is a shame as a number of intriguing papers are alluded
to. Never mind, what is there is good. What is there is plank laid across
the Middle Pleistocene of Africa and Asia.
The lay out of the volume has a pleasing logic and makes the
journey from west to east easier for a dispersing armchair hominin to
conceptualise - apart from a curious U turn at the end back to the Indian
subcontinent.. Four chapters introduce the reader to the big picture.
Professor Deacon takes the first steps and describes the impact of the
1973 conference and its 'sensible temporal benchmarks', lending the
suggestion that much of 1973, reflecting the interests and knowledge
base of the time, was about climate, culture, and chronology. The contributions
in the present volume reflects a continued processualist underpinning
to Middle Pleistocene studies, and these three themes are still very
much in evidence. But the sophistication of supporting theory brought
to bare is very different now. This is shown in Potts, Lahr and Foley,
and Schwarcz's papers. Whether you agree with every aspect of them or
not, these authors present models to explore the relationship between
extinct humans and their physical environments both in Africa and during
dispersal into Eurasia. These are stimulating papers. Schwarcz also
alludes to the Antlantis of dating - the skinflint method, where by
knapped stone could be directly dated. I'm tempted to say dream on -
but what a dream.
The next three papers deal with the archaeological records from
Middle Pleistocene Africa; Deacon and Wurz on South Africa, Barham on
Central Africa and McBrearty on East Africa. These authors show just
how much has changed since the early 1970s. McBrearty and Barham both
describe a number of features in the sites they discuss that would have
raised more than an eye brow in 1973. In the Twin Rivers sites there
are backed pieces, including segments dated to Lupemban contexts between
275 and 170 ka; at Kapthurin points are possibly beginning to appear
in the record at about 500 ka, with blades, many bipolar, being produced
between 500 and 300 ka. Such residues of so called modern behaviour
in MSA and even ESA contexts would have been considered unlikely by
many of the Burg-Wartenstein delegates. Many of these authors ask us
to question the compartmentalised views that slot behaviour, our ability
to associate it to the residues of action, and traditional frameworks
together. They make a persuasive case.
I was disappointed there was no separate chapter on the North
African evidence, although it is woven into one of the succeeding three
contributions. These papers by Hublin, Rightmire, and Brown, concentrate
mostly on the skeletal evidence; Hublin focuses on the North African
record, while Rightmire explores the relationships between the African
and Asian Middle Pleistocene hominins. Brown's contribution is a well
measured piece casting considerable doubt on the presence of hominins
before a million years ago in China. Brown rightly airs the doubts concerning
three of the major early hominin sites, Yuanmou, Longgupo - which initiated
a brief Out of Asia debate - and Gongwangling. (I was particularly interested
in his dismissal of Longgupo Cave. I remember viewing with great scepticism
the stone tool illustrations accompanying the original Nature article
- which even by the execrable standard of artefact drawings in that
normally august journal - looked very dodgy indeed.)
The next set of papers walk us through the complex archaeological
record of China and South East Asia Youping explores the incidents of
early settlement in the Yangtze River Basin, Keates condenses an amazing
amount of information on the archaeology of key Chinese Middle Pleistocene
sites (and inadvertently demonstrates some of the differences in the
historical outlooks of geographically distinct archaeological traditions,
her figure 12.8a, a large 'point' from Dingcun, would in many African
excavations have been classified as a minimally worked handaxe on a
big (>20 cms) side struck flake), and Robson-Brown sets the palaeo-climatic
record of mainland South East Asia against the sparse to non-existent
Pleistocene record in this area. She highlights what an untapped potential
this region is and briefly describes some truly innovative modelling
work to predict areas wherein there may be higher possibilities of discovering
fossils. An interesting adjunct to these Asian papers was a lecture,
not included in this volume, by Potts. He described recent discoveries
in the Bose Valley (now published in Science) of bifaces dated to about
800 ka. This is remarkably in accord with a < 1.0 mya age for hominin
entry into China and South East Asia, particularly given some of the
doubts expressed about early dates from Java.
The final set of papers follow a southern and then a westerly
route as we hike across to Australasia and then backtrack to the Indian
subcontinent. Storm contextualises the Australian evidence for Homo
in terms of the potential for movement of animals and hominins across
the island chains of Sunda and Sahul. I must confess this is an area
I know next to nothing about, and as a 'quick and dirty' introduction
to it, I got a lot out of this contribution. He also alludes to the
fascinating reports of stone tools on the island of Flores at > 700
ka. This island has never been part of a land bridge and the implications
of this, if robust, are quite staggering. Journey's end is Petraglia
and the redoubtable Paddaya both of whom cross the tape with the Middle
Pleistocene of India. Petraglia notes the oldest secure dates are >350
ka, and is certain that when sites with dateable sediments and secure
artefact associations are identified this threshold will greatly increase.
Whether his prediction of greater than 1.0 mya is proved true remains
to be seen. He touches on a fascinating aspect of the Middle Pleistocene
of the Old World. Why oh why are Acheulean bifaces so similar, both
in appearance and in methods of production across such huge planks of
time and space? Petraglia is almost certainly right that learning, and
the adaptive advantage of certain basic skills were under strong selective
pressure. Finally there is Paddaya's contribution on the archaeological
record from the Hunsgi and Baichbal Valleys. Here is one of the jewels
in the Middle Pleistocene crown, a long term extensive regional survey
that has, as Paddaya unabashedly points out, shown the value of surface
and near surface sites in the face of ever growing emphasis on single
locations with deep stratigraphy. Damn right too. Although as time averaged
as any deep gravel deposit with bifaces, Paddaya's paper in this volume
reminds us that Middle Pleistocene landscapes were phenomenally rich,
a factor that single site archaeologies often force us to forget. In
areas like India, and parts of South Africa too, topographic stability,
at least on a medium scale, can allow us insights into landscape use
over time. This is as valid a goal of research as is the more microscopic
scale of site focused investigations. His conclusions, which read like
a District Attorney's list of indictments against the accused are consequently
all the more germane.
This is a great book. It is important in that it crystallises
a huge quantity of diverse temporal and spatial data from a wide variety
of disciplines. It is a worthy successor to After the Australopithecines,
and a must for every Middle Pleistocene book shelf. If that is not praise
enough, it is another notable success for the Western Academic and Specialist
Press.
