Hunting Strategies in Central Europe



Hunter-gatherer cultures differed widely in their dependence on technology.  The persistence hunters of the Kalahari used almost none, while those inhabiting cold regions required huge survival toolboxes — weatherproof shelters, warm hearths, fur clothing, canoes, specialized weaponry, food storage.  In the far north, hunting clans also required dozens of large sled dogs, and feeding them required killing many additional wild animals, all year long.  The utterly simple Kalahari way of life was practiced by our hominid ancestors for two or three million years.  These tropical primates had coevolved with their tropical ecosystem, and elegantly danced to the beat of the land, a vital key for their long-term success.

I was curious to learn more about the hunting cultures of my prehistoric ancestors in snowy Europe, so I plowed through a pile of scholarly books, papers, and websites.  The Stránská skála site near Brno, Czech Republic looked promising.  It held the remains of bison, horses, mammoths, elk, rhinos, bears, and giant deer.  I came across Hunting Strategies in Central Europe During the Last Glacial Maximum, by Dixie West.  Most of the book focused on stone tools and bone fragments found at Stránská skála and another site.  I didn’t find what I was looking for, but the info I found was important for better understanding this chapter of the human saga.

The Last Glacial Maximum (LGM) was the frigid peak of the last ice age, which occurred between 20,000 to 15,000 years ago.  Glaciers retained so much water that sea levels were 410 feet (125 m) lower than today.  A lass could walk from Ireland to Scandinavia or France without getting her feet wet (MAP).  During the LGM, climate became cooler and more arid, which had a serious impact on vegetation, and the animals that depended on it.  Many species that had survived a number of earlier ice ages began to go extinct.  Climate was an important actor in this drama.  Notably, highly skilled human hunters, with state of the art technology, were now well-established residents of Europa.

Once upon a time, mammoth country ranged from Western Europe to Alaska, New England, and Mexico.  Mammoths needed to stay close to water.  Because they were huge, and moved slowly, they couldn’t utilize sparse scattered patches of vegetation, or food too distant from water sources.  Difficult terrain was also off limits for the huge critters.  Each day, an adult needed to eat 440 to 660 pounds (200 – 300 kg) of moist feed, preferably grass.  A horse could get by on 22 pounds (10 kg) per day.

Frozen mammoths have been found, and their guts contained larch, birch, willow, sedge, mosses, and grasses.  They were able to digest both low fiber fresh grasses and high fiber wood, and quickly convert them into mammoth poop.  As the climate became cooler and more arid, their food supply diminished.  European mammoths were stressed by 24,000 years ago.  As the harsh climate intensified, the slow-moving animals had to migrate to warmer regions, which were already occupied by other large herbivores.

In a dryer climate, vegetation became more fibrous, or went dormant.  Seasonal bottlenecks in the food supply for grazing animals increased.  Bison, aurochs (cattle), sheep, and goats digest their preferred food slowly, and a diet higher in fiber would have been a threat to survival, in the driest periods.  They joined the mammoths in drifting toward greener pastures.

Similarly, reindeer had a limited ability to digest cellulose, but they were able to survive because they could quickly travel long distances each day, selectively dining at smaller patches of the most nutritious food.  Another plus was their ability to digest forages that other species could not, like lichens.

Horses were also lucky, because they could thrive on a high fiber, low protein diet.  They had to spend more time grazing on lower quality food, consume larger amounts of it, and expand the size of the territory they grazed.

The LGM made life more challenging for hunters.  Game animals declined in numbers and variety, so more time was spent searching for them.  The lads preferred to take larger animals that provided generous amounts of meat, body fat, marrow, and bone grease.  Fat was very important.  When a carcass provided little fat, more meat had to be consumed to acquire necessary nutrients.  West noted, “If fat is totally absent in the diet, very lean meat should be avoided as it takes a higher metabolism to digest purely lean meat, and predators, including humans, can readily lose weight on a lean meat diet.”

At the kill site, animals were often dismembered, making it easier to haul them back to camp.  They hauled away the prime stuff, and left behind low quality stuff for scavengers to enjoy and recycle.  Marrow was prized, and reindeer bones contained a lot of it.  Horses were twice the size of reindeer, but the deer had 13 times more marrow.  Horses provided lots of protein, but had minimal body fat or marrow.  It wasn’t worth the effort to haul away horse bones and break them apart at camp.

There were two types of horse groups, harems and bachelor herds.  The dominant stallion protected his harem of mares, and the young colts.  Colts were prime targets for predators, but stallions were big, strong, and aggressive — kicking, biting, and stomping all threats.  When hunters attacked a harem, the stallion had to be killed first.  Hunters were less likely to die when attacking bachelors, but less likely to get meat, because bachelors rapidly dispersed in every direction.

For ambush hunting, waterholes were a prime location.  Hunters waited, concealed in blinds.  As the LGM squeezed plant communities, horse herds were forced to scatter more for grazing, making them harder for hunters to find.  During fall and spring migrations, herds could swell to thousands of animals.  They were fattest in the late autumn.  Hunters could kill many by driving them into box canyons, ravines, stone corrals, and other traps.

Reindeer also gathered in large herds for seasonal migrations.  Autumn was the prime season for hunting.  Reindeer were much easier to kill, but these smaller animals provided less protein.  Hunters consumed their meat, blood, fat, marrow, and the milk of (killed) lactating cows.  West adds, “Modern caribou hunters provide evidence that ancient humans could have relied on partially digested gut contents and feces of reindeer to fulfill nutritional requirements.”  Yum!

Antlers were used to make tools.  They could be eaten while in summer velvet.  Fat was burned for light.  After the hunt, hides were prepared for tanning, and meat was butchered for drying or smoking.  Bones were broken to get marrow, and then crushed and boiled to extract the bone grease.  Containers were made from hides, bladders, and guts.  Cordage was made from tendons and sinews.  Hides were used to make blankets, boots, and clothing.

Caribou are close relatives of reindeer.  Each year, 24 hides were needed to maintain a caribou hunter’s wardrobe.  At least 20 hides were needed to make a tent.  Boiled hides were famine food.  From time to time, when adequate vegetation became scarce, the routes of seasonal migrations might change suddenly without warning.  It only took a few weeks for a hunting group to die from starvation.

For me, the moral of this story is that life is vastly easier when tropical primates remain in their tropical motherland, and live as their ancestors had for several million years, relying on a few very simple tools.  Migrating into non-tropical ecosystems, like Europe, demanded serious technological innovation, a dark juju that proceeds slowly at first, gradually accelerates, and then explodes.  Innovation is highly contagious, demonically addictive, and phenomenally destructive in its advanced stages.  Old-fashioned cultures that wisely nurtured voluntary restraint and simple lifestyles were helpless deer in the headlights of runaway innovation, forcing them to leap aboard the Oblivion Express or die.

In her book, The Old Way, Elizabeth Marshall Thomas reported that the traditional Kalahari way of life is over.  Clever lads discovered that enslaved dogs made tracking and hunting much easier.  Later they got enslaved horses, eliminating the need for long distance running.  Then they got guns, which were far deadlier than bows and arrows.  Progress never sleeps.  Guess what happened to the game.  Only a few elders still remember the art of tracking, a million years of time-proven knowledge.

Year after year, we’ve been zooming past countless red warning signs.  Wrong way!  Do not enter!  The path of human-centered thinking is approaching its clearly marked dead end.  Beliefs, spells, and madness got us into this mess — not genes.  Devastating epidemics of status fever are spread via stupid ideas.  Sane ideas are an effective cure.  Imagine that.

Pleistocene Hunting in Europe



Humankind is confronted with an enormous and perplexing riddle.  We’ve developed a way of life that is ecologically super-idiotic (but look at our awesome phones!), and pounding the vitality of the natural world (and soon we’ll have self-driving cars!).  The great riddle is how did we get into this mess?  Can we get out of it?  Who are we?  Where did we come from?

Many books reveal important clues.  Bonobo described our closest living relatives, a species that has remained sustainable for millions of years.  The Art of Tracking revealed our ancient roots as bipedal hunters and scavengers, which kept our ancestors alive for several million years.  Hunters of the Recent Past examined the communal hunting practiced by Homo sapiens who struggled to adapt to living in temperate and subarctic climates, during the last 15,000 years or so. 

Now, I want to peek at life from 40,000 to 20,000 years ago.  This peek looks at the Homo sapiens who had recently moved into Europe — the ancestors of many white skinned folks who are reading my words in English.  In those days, Europe enjoyed an astonishing abundance of wildlife.  Peek at the fantastic cave paintings of Chauvet or Lascaux.

For my tropical primate ancestors to survive in a challenging non-tropical climate, they had to live like moon explorers, with weatherproof shelters, warm clothing, blazing hearths, and a well-stocked food locker for the deep freeze months.  The giant hyenas, cave bears, cave lions, and saber-tooth cats refused to join PETA, and took great delight in brutally killing the delicious primates in fur coats.  Eventually, groups that were clever and lucky figured out ways to exist for a while, riding a scary climate change roller coaster.

Roche de Solutré

At the Roche de Solutré site, near Mâcon, France, archaeologists have found the remains of up to 100,000 horses.  Prior to 1866, when experts realized the bones were prehistoric, local farmers had been hauling them away for many years, using them for fertilizer.  In some places, the surface of the ground was paved with ancient horse bones.  The valley was a common route for the migrations of animal herds.  In the summer months, herds grazed at higher elevations to avoid heat and insects.  Winter months were spent grazing on the warmer floodplain of the Saône River.

The bone beds were located fairly close to the bottom of a steep limestone cliff.  For years, folks theorized that the horses had been killed by driving them over the edge.  At this site, a more likely scenario was that hunters drove the animals into natural rock corrals, or box canyons, where they were trapped.  Once cut off from escape, they were killed, butchered, dried, and smoked.  Wild horses were extremely dangerous prey.  Big strong stallions would aggressively attack hunters, and stomp them to bloody bits.

The oldest bones are 55,000 years old, horses killed by Neanderthals.  They were covered by six feet (1.8 m) of sterile soil.  The next layer is deep, containing the remains of animals killed by Homo sapiens between 37,000 and 10,000 years ago.  Prior to 22,000 years ago, the majority of bones were horses.  After that, reindeer bones were dominant.  This was an era of climate shifts.

Předmostí

Předmostí is near the city of Přerov, in the Czech Republic.  It is located at the southern end of the Moravian Gate, a narrow corridor that passes between the Carpathian Mountains to the east, and the Sudeten range in the west, linking southern Poland and Moravia.  It has long been a strategic trade and communications route.  Naturally, it was also a route for the seasonal migrations of game animals in the Pleistocene, including mammoths.

Předmostí has the largest mammoth bone accumulations in central Europe.  The skeletons of more than a thousand have been uncovered so far.  Mammoth bones were used in the construction of their huts.  Excavations have found hearths, a cemetery, stone and bone tools, and carvings made from mammoth ivory.  One carving has been named the Venus of Předmostí. 

Folks inhabited Předmostí between 27,000 and 25,000 years ago, and again later, about 20,000 years ago.  During this time period, at many locations in central Europe, numerous Venus figurines have been found.  HERE are some examples.  The figurines inspired archaeologist Marija Gimbutas to imagine a paradise of goddess worshipping people that preceded the dark arrival of patriarchy and bloody warfare… a pleasant dream.

Dolní Věstonice

Dolní Věstonice and Pavlov are small neighboring villages north of Mikulov, in the Czech Republic.  In the twentieth century, when a villager decided to dig a cellar, he discovered the remains of a large dwelling built with mammoth bones and tusks.  Multiple excavation sites in these villages have revealed fascinating details about Pleistocene hunters, who lived there from 29,000 to 24,500 years ago.  They lived on terraces overlooking the river, where they had an excellent view of the vast treeless steppe below.  These huts were common in central Europe.  HERE is a map of them, and HERE are many images of mammoth bone huts.

At one camp, four huts were located close together, and the small settlement was surrounded by a low wall made of mammoth bones and rocks, covered with brush and turf.  The huts were something like teepees, covered with animal skins.  They had a circular foundation made of rocks and heavy bones.  Between the huts was a large outdoor fire pit.  Up the hill was a small hut containing a kiln for baking clay.  This is the earliest evidence of making ceramics (they did not make pottery).  They created a variety of figurines, including the heads of bears, foxes, and lions, and female figurines with bulging breasts and buttocks.  These may be the earliest art.

At a nearby location, the largest lodge was 50 feet long (15 m) by 20 feet wide (7 m), and had five hearths.  At one hearth, two long mammoth bones were stuck in the ground, to support a roasting spit.  Southeast of the lodge were piles of bones, including about 100 mammoths, mostly young.  There were also bones of horses, reindeer, hares, wolves, and foxes.  At one dig, they found the remains of a child wearing a necklace with 27 fox teeth.  The skull was covered with red ochre, and the body was covered with the shoulder blades of mammoths. 

Artists have studied the skulls found in the area, and made paintings of what the people would have looked like in life.  When exhibited in Prague, the portrait of a prehistoric wild woman embarrassed the public — because she looked too modern, not like a dirty primitive beast — she looked like the proper and dignified ladies in the gallery (gulp!).  Many awesome paintings can be found HERE.

Great Leap Forward

The sites mentioned above existed prior to the Last Glacial Maximum (20,000 to 15,000 years ago), an era of intense cold that froze out many species of flora and fauna.  Some human supremacists see these mammoth hunters as a glorious breakthrough in the human saga, when we finally ceased being ordinary animals — dumb brutes unable to sing, speak, reason, make ornaments, paint caves, invent deities, or become entranced by smart phones.  They call this transition the Great Leap Forward — a miraculous advance as important as the Industrial Revolution.  (Of course, this could only take place in Europe, home of the most brilliant humans of all.)

The Pleistocene epoch spanned from 2.6 million years ago, to 11,700 years ago, and it included many intense ice ages.  At the end of the Pleistocene, there was a surge of extinctions; a large number of megafauna species vanished in North America, mostly between 12,000 to 10,000 years ago.  Some experts blame humans for overhunting, others blame climate change, and many blame a combination.

In Europe, fewer extinctions occurred, and they took place over a longer period of time.  Many of the species that went extinct were giant-sized, compared to their modern relatives.  Cave bears and European hippos vanished around 24,000 years ago — both species had been around for over a million years.  Homotherium, a genus of saber-tooth cats, existed for five million years before vanishing 28,000 years ago.  European cave lions vanished 10,000 years ago, after 1.9 million years.  Cave hyenas were gone by 11,000 years ago, after 3.5 million years.  Irish elk were gone by 8,000 years ago, after 400,000 years in Europe.  Woolly mammoths were gone by 14,000 years ago, after 400,000 years.  Woolly rhinoceros vanished 10,000 years ago, after 3.6 million years in Eurasia.

Was the Great Leap Forward a great booboo?  Did overhunting encourage the emergence of agriculture and civilization?  Should we have stayed in tropical Africa, and skipped our nightmarish experiment in technological innovation?  Why don’t bonobos need psych meds?  Good luck with the riddle!  Have a nice day!
