Technology is allowing anyone to contribute to scientific research, with implications for conservation, disease prevention and much more.
More and more evidence suggest that we could potentially face runaway climate change at a much faster rate than anticipated. The videos Arctic Methane: Why the Sea Ice Matters and Arctic Death Spiral and the Methane Time Bomb presents a sobering analysis of the latest data on disappearing Arctic sea ice. James Hansen warns in a new paper that we are on the verge of crossing a tipping point into catastrophic climate change. Accelerating warming may release methane from permafrost and the ocean floor, creating a positive feedback cycle of increasing warming and increasing release of methane, resulting in potential catastrophic runaway global warming.
While the evidence suggesting potential runaway climate change is cause for concern, I believe the outcome will be determined by a race between climate change and change brought about by science and technology. It is clear that political change and social change will not provide solutions to climate change. Only rapid innovation in science and technology will be able to provide solutions that can deal with the rapidly increasing problems we face. We need runaway science – we need scientific innovation that can outpace the threats posed by runaway climate change.
Over the last 100 000 years science has grown at an accelerating rate. The next ten to twenty years may see innovation in science and technology orders of magnitude greater than what we have witnessed in the last 100 years. Much of this acceleration may come from citizen science, from self-educated independent scientists. The greater the number of people who get involved in science, the greater the chance of a Black Swan solution not anticipated at present. We cannot depend on politicians to increase science budgets to solve the problems we face. Rather, young people need to take the initiative and follow their passion for science.
The Origin of Science
CyberTracker has grown from a simple hypothesis: The art of tracking may have been the origin of science. Science may have evolved more than a hundred thousand years ago with the evolution of modern hunter-gatherers. Scientific reasoning may therefore be an innate ability of the human mind. This may have far-reaching implications for indigenous knowledge, citizen science and self-education.
The Persistence Hunt
In 1990 I ran the persistence hunt with !Nate at Lone Tree in the Kalahari. The persistence hunt involves running down an antelope in the mid-day heat on an extremely hot day – chasing the antelope until it drops from heat exhaustion. This may well be one of the oldest forms of hunting, going back two million years ago, long before humans invented bows and arrows. Persistence hunting may have played a critical role in the evolution of the art of tracking and the origin of science.
In 2001 I worked with David Attenborough on the BBC film showing Karoha doing the Persistence Hunt. You can watch Karoha running down a kudu in the video at
Reviving the Dying Art of Tracking
After running the persistence hunt in 1990 !Nate asked me to help them. They could no longer live as hunter-gathers and needed jobs. Wildlife in the Kalahari has been decimated by fences that cut off migration routes. It was no longer viable to live as hunter-gatherers. And the art of tracking was dying out. After hundreds of thousands of years, traditional tracking skills may soon be lost. Yet tracking can be developed into a new science with far-reaching implications for nature conservation.
We had lengthy discussions around the fire, and it was decided that I should try to find a way to create jobs for trackers. Only by developing tracking into a modern profession, will tracking itself survive into the future. !Nam!kabe agreed that this will be good for the future. But he also had the wisdom to know that it will take a long time. This was for the younger generation, he said, it will not be for him. When he died in 1995 his exceptional tracking expertise was irretrievably lost. He was one of the last of the old generation hunters and one of the best trackers. !Nam!kabe inspired the creation of the Master Tracker certificate – the highest standard of tracking that others could aspire to.
The Tracker Evaluation methodology that I developed provide certification of practical tracking skills, thereby enabling trackers to get jobs in ecotourism, as rangers in anti-poaching units, in wildlife monitoring and scientific research. Tracker evaluations have since 1994 resulted in a steady growth of trackers with increasing levels of tracking skills, thereby reviving tracking as a modern profession.
The Tracker Institute was established as a centre of learning for the highest standards of excellence in the art of tracking and to develop the next generation of Master Trackers. The Tracker Institute is situated in the Thornybush Nature Reserve, providing the opportunity to track lion, leopard, rhino and a wide diversity of species. In addition to providing intensive individual mentoring of practical tracking skills, it will also serve as a research institute.
If the art of tracking was the origin of science, then modern-day trackers should be able to do science. However, some of the best traditional trackers in Africa cannot read or write. To overcome this problem, the CyberTracker software was developed with an icon-based user interface that enabled expert non-literate trackers to record complex geo-referenced observations on animal behaviour.
In 1996 I teamed up with Justin Steventon, a brilliant young computer science student at the University of Cape Town. The CyberTracker user interface was developed with the help of Karel Benadie, a tracker working in the Karoo National Park in South Africa. Together with fellow ranger and tracker James Minye, they tracked the highly endangered Black Rhino, recording their movements and behaviour in minute detail. Together we published a paper on rhino feeding behaviour in the journal Pachyderm. This is perhaps the first paper based on data gathered independently by two non-literate trackers, confirming a hypothesis about rhino feeding behaviour put forward by the trackers. It was a demonstration that non-literate trackers can do science.
In 2008 the Western Kgalagadi Conservation Corridor Project was initiated, funded by Conservation International for a three-year period. Community members from several villages were employed to use the CyberTracker to conduct track counts. This was the first time that !Nate and Karoha were employed in a major research project, enabling them to use their traditional tracking skills, using the CyberTracker, in a modern context.

Involving scientists and local communities in key areas of biodiversity, CyberTracker combines indigenous knowledge with state-of-the-art computer and satellite technology.
Towards a New Science
From its origins with the Kalahari Bushmen, CyberTracker projects have been initiated to monitor gorillas in the Congo, butterflies in Switzerland, the Sumatran rhino in Borneo, jaguars in Costa Rica, birds in the Amazon, wild horses in Mongolia, dolphins in California, marine turtles in the Pacific and whales in Antarctica.
CyberTracker is being used by indigenous communities, in national parks, scientific research, citizen science, environmental education, forestry, farming, social surveys, health surveys, crime prevention and disaster relief.
The CyberTracker story is captured in the powerful image of Karoha holding the CyberTracker, with his hunting bag slung over his shoulder. The image symbolises the cultural transition from hunter-gatherer to the modern computer age. Persistence hunting may be the most ancient form of hunting, possibly going back two million years, long before the invention of the bow-and-arrow or the domestication of dogs. After two million years, Karoha may well be the last hunter who has been doing the persistence hunt. Yet of all the hunters at Kagcae, Karoha is the most proficient in using the CyberTracker. In Karoha, one individual not only represents one of the most ancient human traditions, but also the future of tracking with computers.
Karoha’s story represents the most profound cultural leap – a story that gives hope for the future: The ancient art of tracking can be revitalized and developed into a new science to monitor the impact of climate change on biodiversity.
At a more fundamental level, it shows us that anyone, regardless of their level of education, whether or not they can read or write, regardless of their cultural background, can make a contribution to science.
In The Origin of Science I address one of the great mysteries of human evolution: How did the human mind evolve the ability to develop science?
The art of tracking may well be the origin of science. Science may have evolved more than a hundred thousand years ago with the evolution of modern hunter-gatherers. Scientific reasoning may therefore be an innate ability of the human mind. This may have far-reaching implications for self-education and citizen science.
The implication of this theory is that anyone, regardless of their level of education, whether or not they can read or write, regardless of their cultural background, can make a contribution to science. Kalahari Bushmen trackers have been employed in modern scientific research using GPS-enabled handheld computers and have co-authored scientific papers. Citizen scientists have made fundamental contributions to science. From a simple observation of a bird captured on a smart phone through to a potential Einstein, some may be better than others, but everyone can participate in science.
Today humanity is becoming increasingly dependent on science and technology for survival, from our dependence on information technology through to solving problems related to energy production, food production, health, climate change and biodiversity conservation. Involving citizens in science may be crucial for the survival of humanity over the next hundred years.
Scientific reasoning was part of hunter-gatherer culture, along with music, storytelling and other aspects of their culture. Science and art should be an integral part of human culture, as it has been for more than a hundred thousand years.
