Aurochs



It’s Aurochs Appreciation Week.  Aurochs were the wild ancestors of today’s herd of 1.3 billion domesticated cattle.  They were huge, strong, and fierce — the opposite of the passive cud-chewing manure makers of today.  In regions having ideal conditions, bulls could grow up to 6 feet (180 cm) tall at the shoulder, and weigh up to 3,300 pounds (1,500 kg).  Their horns were much longer than cattle, and pointed forward, aggressively.

Some believe that the species emerged in India between 1.5 and 2 million years ago.  They survived in a world along with similarly large, strong, and fierce predators.  Eventually their range spanned from England to China.  Aurochs’ preferred habitat was dense ancient forests with lakes, rivers, bogs, and fens.  They didn’t hang out in frigid tundra regions with woolly mammoths.

Some say Neanderthals emerged 600,000 years ago, and others say 350,000.  They had migrated into Europe by 250,000 years ago, and went extinct around 30,000 years ago.  During their long visit in Europe, Neanderthals hunted aurochs with wooden thrusting spears, but did not drive them to extinction.  Mark White’s team wrote a fascinating paper on five ancient sites where Neanderthals had hunted steppe bison, aurochs, rhinoceros, horses, and reindeer.  They discussed the La Borde site in France, where aurochs were driven into a collapsed cavern, a pit trap.

In 1971, La Borde was discovered by chance, and largely destroyed, by a construction project.  During rushed rescue excavations, the remains of 40 aurochs were found at the site, and far more were likely destroyed by the machines.  Most of the animals were juveniles, and most adults were cows.  Avoiding adult bulls was an intelligent way for hunters to avoid a premature death.  Neanderthals combined their knowledge of aurochs behavior with their knowledge of the land’s topography, to select the prime location for a bloodbath, and then guide the animals into it.  Their knowledge was more powerful than their weapons.  This trap was used many times.

Maybe 45,000 years ago, Homo sapiens arrived in Europe.  Some are beginning to wonder if our visit on Earth will last as long as the Neanderthals.  In France, aurochs were painted in the Lascaux cave 17,000 to 13,000 years ago, and carved on the walls of Caves de la Mairie 15,000 years ago.  Aurochs disappeared on the Danish islands by 5500 B.C., from Britain by 1500 B.C., from the Netherlands by 400 B.C.  They still survived in Germany when Julius Caesar visited around 50 B.C., to harass the Suevi and other wild tribes. 

The Hercynian forest once spanned east from the Rhine, across modern Germany, to the Carpathians, and all the way to Dacia (present-day Romania).  A quick traveler could cross the forest north to south in nine days, but it was very long, from east to west.  Caesar noted, “There is no man in the Germany we know who can say that he has reached the edge of that forest, though he may have gone forward sixty days’ journey, or who has learnt in what place it begins.”  Pliny also mentioned it:  “The vast trees of the Hercynian forest, untouched for ages, and as old as the world, by their almost immortal destiny exceed common wonders.”

Caesar also commented on aurochs, animals “a little smaller than elephants, having the appearance, color, and shape of bulls.  They are very strong and swift, and attack every man and beast they catch sight of.  The natives sedulously trap them in pits and kill them.  Young men engage in the sport, hardening their muscles by the exercise; and those who kill the largest head of game exhibit the horns as a trophy, and thereby earn high honor.  These animals, even when caught young, cannot be domesticated and tamed.”

Charles the Great, or Charlemagne (747 – 814), once had a painful encounter while on a hunting trip.  When an aurochs appeared in the forest, his hunting buddies fled in terror.  Charlemagne was less intelligent.  He rode up to one, drew his sword, and pissed off the monster, who gored his leg.  From that day forward, the humbled king walked with a limp.

The famous explorer Marco Polo (1254 – 1324) also described them.  “There are wild cattle in that country as big as elephants, splendid creatures, covered everywhere but on the back with shaggy hair a good four palms long.  They are partly black, partly white, and really wonderfully fine creatures.”

In Russia and Hungary, aurochs were last seen in the twelfth and thirteenth centuries.  In Germany, they had blinked out by the fifteenth century.  Aurochs made their last stand in Poland.  As agriculture expanded, Europe’s ancient forests and wetlands vanished.  Grain farmers detested aurochs molesting their crops, and herders resented them dining on prime forage.  Aurochs stood in the path of progress.

Anton Schneeberger (1530 – 1581) was a Swiss botanist and doctor based in Poland.  He once wrote a letter to Conrad Gesner, who included it in a book published in 1602.  He wrote that aurochs had no fear of humans, and did not flee from their approach.  When they were teased or hunted, they got very hot-tempered and dangerous, sometimes hurling idiots high into the air.

Cis van Vuure wrote the book on aurochs.  He thought that domestication began about 9,000 years ago, in the Middle East and Pakistan.  As the powerful intelligent gray wolf was reduced to the neurotic poodle, so the mighty aurochs was reduced to countless variations of dimwitted cattle, fine-tuned for specific climates and uses (meat, hides, milk, draught).

It’s hard to imagine such notoriously fierce animals being forced into slavery.  Dogs and horses were likely enslaved at multiple locations independently.  Alasdair Wilkins wrote about recent DNA research on cattle.  The ancestors of every cow in the world trace back to a tiny herd in the Middle East, a herd as small as 80 animals.  The process of domestication may have taken a thousand years, and it was likely done by sedentary people.  It would have been impossible for nomadic herders to confine huge powerful animals with a tremendous love of wildness and freedom.

Meanwhile, back in Poland, the forests kept shrinking, as did the number of aurochs.  Farmers and hunters kept killing them.  Many likely fell to the devastating diseases of domesticated herds, like anthrax.  People became concerned at their decline, and guards were hired to discourage poaching, but the rapidly growing civilization had no room for them.  The last aurochs died in 1627, in the Jaktoróv forest, in Warsaw province of Poland.

Thus, the steaming beef in a hamburger comes from the bovine equivalent of a poodle, an unhappy meal indeed.  The aurochs were displaced from their vast territory, and eventually eliminated by heavily armed tropical primates.  The unusual primates have displaced the wolves, grizzlies, rhinos, bison, cod, whales, the Hercynian forest, and on and on.  Look at us.  How have we been changed by this rampage?  I raise my glass to wildness and freedom, and pray that the terrible hurricane soon loses its fury, and makes way for the dawn of a Great Healing.

Pandora’s Seed


Spencer Wells is a geneticist who gathers DNA samples from around the world and uses them to analyze evolutionary history.  Mutations occur from time to time, and they provide landmarks in our genetic history.  Following a mutation, the new characteristic is passed along to future generations.  A region where the new characteristic is found in unusual density is marked as its place of origin.  Wells can also distinguish old mutations from recent ones, based on how common they are.  So, each mutation is marked with a time stamp and a place stamp.  Using these markers, and your DNA, Wells can go to a world map and plot the meandering journey of your ancestors’ migration out of Africa. 
Genetic historians perceive the journey of humankind in a unique manner.  Based on gene markers, they have theorized that humans nearly went extinct around 70,000 to 75,000 years ago, dwindling down to 2,000 to 10,000 individuals.  This corresponds with the huge eruption of Mount Toba in Sumatra, which spewed massive amounts of dust into the atmosphere.  Global temperatures dropped from 9° to 27° F, and the weather stayed cool for 1,000 years.
The ancestors of Neanderthals moved to Europe about 500,000 years ago, and they overspecialized for life in temperate forests.  Our ancestors migrated out of Africa 60,000 years ago, and arrived in Europe 35,000 years ago.  A few thousand years later, the Neanderthals were gone.  Europe was in an ice age 35,000 years ago, and the forests had changed to grasslands and tundra.  Neanderthals were not well suited for hunting on open ground.  The humans had better weapons, better hunting skills, and travelled in larger groups. 
Our tool-making skills increased significantly around 60,000 years ago, and we may have been pushed out of Africa by population pressure.  The arrival of the cave painting era, 40,000 to 50,000 years ago, provides clear evidence that we had acquired abstract thought.  This era of big changes has been called the Great Leap Forward.  Recent evidence suggests that this era of advance may have started as early as 70,000 years ago. 
Moving out of Africa presented us with a radically different survival game, and this encouraged us to be innovative and adaptable.  So did the wild mood swings of the climate.  Wells, who sees the world through gene-colored glasses, suspects that abstract thinking was the offspring of one or more genetic mutations.  Once we had acquired this dangerous juju, we were able to jump onto the high-speed train of cultural evolution.  Sadly, we have yet to be blessed with mutations that provide the powers of foresight or wisdom. 
So, for 60,000 years we’ve been stuck in a vicious cycle of out-of-control innovation, and this madness kicked on turbo thrusters about 10,000 years ago, with the Neolithic Revolution — the dawn of farming and civilization.  We entered into a long era of unusually warm and stable weather, which opened the floodgates to many new possibilities, and many new mistakes.
At this point, the feces hit the fan, in impressive quantities.  Everything that had worked pretty well for tens of thousands of years got blown out of the water.  The quality of our diet plummeted.  Our teeth began rotting from a grain-based diet.  Our enslaved animals generously shared their disease pathogens with us, shooting us off into an era of catastrophic pandemic disease.  Growing population led to growing empires and growing warfare.  We got shorter, sicker, and died younger.  We lost our ancient freedom and became “a group of worker bees with looming deadlines to meet.” 
Well’s book, Pandora’s Seed — The Unforeseen Cost of Civilization, does not present us with a miraculous epic of progress.  Agriculture totally changed our relationship with nature, and not for the better.  We quit finding food, and started creating it.  “Instead of being along for the ride, we climbed into the driver’s seat.”  Our numbers exploded, but our quality of life declined. 
Today, at the zenith of our tool-making juggernaut, we’re killing ourselves with a high-calorie crap diet, and an addiction to motorized transport.  A wide variety of degenerative diseases, rare in earlier centuries, have become quite popular.  We tend to be obese, and our rates of mental illness are rising sharply.  The World Health Organization predicts that by 2020, mental illness will be the second most common cause of death and disability, following heart disease. 
The book gets wobbly near the end, as it contemplates solutions.  Wells clearly understands that our current way of life is a dysfunctional disaster, and he hopes that we can find a sustainable long-term solution, but his recommendations get dodgy.  This is a normal problem with any book that attempts to sneak as much cool technology as possible into a “sustainable” tomorrow.  Many have tried, none have succeeded. 
“I’m not advocating a return to a hunter-gatherer lifestyle, of course….”  Why not?  At some point in our collapse, if we’re lucky, hunting may once again become a real possibility.  He doesn’t reveal how we’ll be able to indefinitely continue agriculture as water supplies are rapidly being depleted, as erosion continues the process of converting cropland into wasteland, and as the end of the cheap energy bubble is leading us toward the end agriculture as we know it.
Writing in the months prior to the Fukushima disaster, Wells thought it was time for a second look at nuclear energy, “as nuclear waste disposal methods become increasingly sophisticated and power plants become safer and more efficient.”  Better electric cars are coming out all the time.  If we don’t develop new forms of energy, our only alternative would be radical change. 
We are never more innovative than when we are up against the wall.  Maybe we’ll come up with some cool ideas.  The bottom line is that we need a new worldview, followed by a new lifestyle.  We need to live far slower, and waste far less.  Great!
Finally, Wells reveals his biggest fear, a nightmare future where fundamentalists try to take over the world.  Both Christian and Muslim fundamentalists detest modern life, and want to return to the good old days, by any means necessary.  Here on the west coast, Christian fundamentalism is far from putting a stranglehold on society.  But Wells was born in Georgia, raised in Texas, and schooled at Harvard, so his paranoia is understandable.
