Summary of the impact
The domestication of animals — some ten thousand years — ago has allowed
important insights into
the origins and spread of farming across the globe and the impact that had
on human biology and
culture. Research carried out by an international research group, led by
Aberdeen and Durham
Universities, has brought understanding of this fundamental change in
human history to a broader
public, resulting in impacts on culture and quality of life. The research
findings have featured widely
in TV and radio programmes, both in Britain and abroad. The main
researcher was also invited to
participate in a six-month (privately-funded) experimental sailing
expedition that traced the
migration route of ancient Austronesian settlers into the pacific, which
led to the collection of
unique samples for research. The voyage resulted in a film and a book.
Underpinning research
The change from hunting and gathering to farming is perhaps one of the
most important milestones
in human evolutionary and cultural history. The domestication of plants
and animals led to a
fundamental shift in human diet and health, an explosion of human
population and culture, not to
mention unprecedented changes to the animals and plants involved and on
the environment. This
transition has led to an irrevocable shift in how humans impacted the
planet over the last 10,000
years, a process that continues to this day. The study of animal
domestication is therefore crucial
for gaining a fuller understanding of how it began, what were the
processes involved, how it spread
around the world and what was its impact? Such research provides key
evidence for making more
informed predictions about the future.
Keith Dobney, Sixth Century Professor of Human Palaeoecology at the
University of Aberdeen
since 2009, has dedicated a substantial part of his work to the study of
bioarchaeology, with a
particular emphasis on the domestication of two iconic animals: pigs and
(more recently) dogs.
This research — begun at the University of Durham in 2000 — has steadily
built both an international
and interdisciplinary research group that is one of the most productive
and respected in the
discipline. Underpinned by a number of research awards from the Natural
Environment Research
Council (NERC), Arts and Humanities Research Council (AHRC) and the
Leverhulme Trust,
Dobney has built a novel research model that integrates advances in
genetics (specifically the field
of ancient DNA) with morphology (advanced shape analysis through geometric
morphometrics).
Applying this approach to both fossil remains and recent populations has
allowed Dobney's group
to examine in new ways the factors that drove and shaped animal
domestication. The findings
challenge many previous assumptions about the biological and cultural
basis for early animal
domestication as well as prehistoric models of human migration and
colonisation history across the
globe.
A 2009 examination of pig taxonomy and domestication in Island South East
Asia (ISEA) [1] found
molar shape analysis to be a useful tool for providing a better
understanding of the evolutionary
history of wild pigs in what is an extremely important region for the
study of early farming and
human dispersal. A subsequent examination of early Neolithic pig
domestication in China (2009-2011)
confirmed the Yellow River region to be one of the earliest centres of
independent pig
domestication in the world. [2]
Also in 2009-2011, Dobney and colleagues from UCL examined existing
published records of
400,000 animal bones from archaeological sites in South West Asia and
South East Europe, using
databasing and a variety of statistical techniques to evaluate earlier
models of animal
domestication history in the Near East and the spread of agriculture to
Europe. The research
demonstrated new evidence for regional variation in animal exploitation,
and opened up important
implications for understanding the domestication process itself. [3]
Two further research projects (2010-2013) provided detailed insight into
the domestication process
and dispersal of domestic and commensal animals into and across Europe,
alongside early
agriculturalists. The first [4] focused on pigs, resulting in new evidence
for wild boar lineages
involved in domestication, later wholesale genetic turnover of Near
Eastern pig lineages and
introduction of European domestic pigs into Asia Minor. The second [5]
studied the Orkney Vole
and revealed new evidence for both the timing of its introduction by
Neolithic farmers to the Orkney
Islands and its specific geographic origin in continental Europe.
In 2012, Dobney and colleagues revisited the evidence for dog
domestication across the Old World
(securing a major NERC grant in the process). Examining modern genetic
data from dogs and
wolves, alongside a worldwide assessment of the earliest dog remains, the
group then matched
the alleged geographic locations of so-called existing "ancient" breeds to
the current
zooarchaeological evidence for dog domestication. The results were
counterintuitive, showing that
none of the ancient breeds derive from the regions where the oldest
archaeological remains have
been found, and that three of them even originate from outside the natural
range of Canis lupus
(the dog's wild ancestor). These findings showed that most of the recent
claims for dog
domestication based on genetic data from modern breeds to be false. [6]

Details of the impact
The research described has had considerable impact through a wide range
of TV and radio
programmes, raising public awareness and understanding of the history of
domestic animals — and
what it reveals about human colonisation history — in Britain and abroad.
Through these and other
engagements, the research has contributed to culture and quality of life,
as well as enabling
economic impacts through film and book sales.
Dobney discussed his findings twice on BBC Radio 4's flagship science
programme, Material
World in June 2010, to explain how his findings on pigs have shed
new light on how humans
colonised islands in the Pacific; and in June 2013, to discuss the
challenges and wider importance
of new DNA sequences from a horse dating back more than 700,000 years. [1]
As part of Radio 4's
programme offer, Material World has a reach of nearly 11 million
listeners, according to June 2013
Rajar figures. After each of these appearances, Dobney received 20-30
direct audience responses.
Dobney and colleagues in Durham also acted as consultants for the
six-part BBC2 Horizon series,
The Secret Life of the Dog, broadcast in January 2010 and repeated
in October 2012. Drawing on
their research, the group advised the programme makers on early evidence
of the domestication of
dogs. [2] The series was reviewed in The Guardian newspaper [3]
and on online fora such as
channelhopping.onthebox.com, both of which called it "fascinating". On
YouTube, part 1 alone had
attracted over 35,000 views by the end of July 2013. The series was also
shown in Australia (latest
repeat September 2011) and on the BBC HD Channel (October 2012).
Another BBC2 documentary, A History of Ancient Britain (series 1,
part 2), drew on Dobney's
research into commensal rodents (February 2012). The programme examined
the story of how the
first farmers arrived in Britain from Europe in 4000BC. [4]
A National Geographic programme, How Man Tamed the Wild, also
relied on Dobney's research,
using information he supplied to programme makers and featuring an
interview with him [5]. The
programme was broadcast on the National Geographic and History Channel in
November 2010
and then released as a DVD and sold to French TV. Dobney received numerous
emails from
viewers in response, which were mostly very positive about his approach to
viewing animal
domestication. The Discovery Channel featured the group's research in a
documentary entitled
Prehistoric Dog Domestication Derailed by the Ice Age (July 2011).
[6] Viewer feedback from the
programmes above revealed both a widespread fascination with the subject
matter, and a
particular interest among people with a professional connection, such as
dog breeders and
farmers.
The research has also featured In newspapers, such as Aberdeen's The
Press and Journal (May
2010), which focused on the research into pigs in South East Asia; and on
a range of news
programmes and outlets, including BBC North East Scotland (May 2012) and
NBC News (July
2011). [7]
One particularly interesting impact involved the "Lapita Voyage" [8], a
six-month voyage
undertaken in Nov 08-April 09 following the migration routes of ancient
Austronesian settlers.
Dobney was invited to join five of the participating scientists because of
his research expertise in
this area. During the voyage, unique hair and feather samples were
collected of domestic animals
for genetic analyses. The voyage was accompanied by a film crew, who
produced a feature-length
documentary for German public broadcaster ZDF. Wagnis in der Südsee:
Das Rätsel der
Polynesier was first broadcast in 2010, repeated in July 2013 and is
still available for online
viewing [9]. A 2011 popular book by German expedition leader Klaus
Hympendahl (featuring a
section written by Dobney) sold several thousand copies in Europe by June
2013, with sales
revenues estimated to be between €50-100,000. The paperback edition was
published in May
2013. [10]
Dobney has also engaged with the public through lectures on his work,
e.g. a TechFest lecture in
Aberdeen in September 2011. This was attended by a paying audience of
around 200 people,
many of whom told Dobney afterwards that he had encouraged them to look at
domestic animals in
a new way. Similar numbers attended Dobney's talk at the British Science
Festival in Aberdeen in
September 2012, and another at the University of Basle in May 2013, which
attracted both
members of the public and Swiss government officials.
Beyond this engagement at popular level, Dobney has contributed to a
changing understanding of
prehistory among those dealing with it professionally. His findings have
helped create a new
appreciation of the impact of humans on the early Holocene, or
`Anthropocene' as it is now more
commonly called. This paradigm shift has begun to be reflected in public
discourse and in new
museum exhibitions around the world.
