Technological
Innovation
When a hungry chimp snatches a small monkey, termite, or bird
egg, all she needs to eat it are fingers and teeth. When a hungry baboon discovers a carcass
abandoned by lions, he can chew the meat and fat off the bones and hide. It’s very different when a persistence hunter
chases a large kudu until it is exhausted, and then suffocates it. What now?
Imagine turning a road kill deer into a feast without a knife. Have a bloody good time!
Chimps use slender sticks to fish for termites. They use clubs and rocks to aggressively
attack critters that annoy them.
Macaques use stones to smash open shellfish. Vultures use rocks to open ostrich eggs. Ravens use gravity to crack open the nuts they
drop. This is not complex technology.
Our ancestors began a transition from found tools to
manufactured ones. The oldest ones discovered
so far, mostly simple choppers, were found in Africa, and date to about 2.5
million years ago. A major advance emerged
around 1.5 million years ago — biface knapping.
Some types of rocks, like obsidian or flint, can be carefully knapped to
knock off flakes having razor sharp edges.
These were useful as scrapers, knives, and choppers. Later, ancestors learned how to knap long
sharp blades, and attach them to handles.
Still later, they became skilled at chipping flakes into delicately shaped
spear points and arrowheads.
We glowing screen people arrogantly smirk at the primitive
technology of our early Stone Age ancestors.
In reality, stone tools were revolutionary inventions that shifted the
hominin saga onto a new, unusual, and risky path. For the first time, folks could effectively
skin and butcher large animals — an ability that greatly expanded their food
resources, and provided high quality nutrients for their jumbo-sized energy-guzzling
brains. Imagine a world in which teeth
were the only cutting edges for any purpose.
Civilization would be impossible, and hominins may have never evolved.
Kathy Schick and friends once successfully butchered a dead
elephant with stone tools. A mature adult’s
rugged hide is about one inch thick (2.4 cm).
Scavengers like hyenas don’t even bother trying to chew into the carcass
of an elephant that recently died. They
let it bake in the sun for a few days, allowing decay to soften it up.
Our ancestors used sharp cutters to remove hides, cut meat
off bones, and dismember the carcass into portions easier to haul back to
camp. They used stone hammers to smash
open bones, to extract the marrow, which was rich with fat. Fat is an essential nutrient, and the meat of
wild game has only one-seventh of the fat found in supermarket beef, according
to Schick. Ancestors may have scavenged
elephant carcasses, but adult pachyderms may not have been prime targets for
hunters. Once you strip the meat off of
the exposed side, flipping over a dead elephant is a huge challenge. Smaller game takes less effort.
We have no idea when spear technology was first
developed. It could have been two or
three million years ago. Wooden
artifacts are highly prone to decompose over time. Spears were also revolutionary. They made it easier to kill large game, and allowed
the ancestors to be less dependent on scavenging. Spears were also useful for discouraging
attacks from man-eating predators.
Thrusting spears, or lances, were driven directly into the
prey by hungry hunters, at close range.
Javelins were thrown spears that could kill from a distance, which was
much safer. Carleton Coon mentioned a
tribe that could hurl long spears with deadly accuracy from up to 180 feet away
(55 m).
The oldest spears found so far were discovered in a coal mine
at Schöningen, Germany. Frederick
Coolidge wrote that seven spruce spears, a throwing stick, and other tools were
found near ten butchered horse carcasses.
The spears were 400,000 years old, up to 6.5 feet long (2 m), scraped
smooth, and pointed at both ends. They were
made by the ancestors of Neanderthals (Homo
heidelbergensis). The fact
that Neanderthals could survive for hundreds of thousands of years using such
simple weapons is evidence that they lived in a time when large game was
abundant, and it was proof that they were not dummies.
The killing power of spears was boosted by the invention of
the atlatl, a spear-throwing device that enabled the weapon to be hurled
farther and faster. Alfred Crosby noted
that in Peru, an Incan warrior with an atlatl could send a short spear
completely through a conquistador wearing metal armor.
Eventually, nobody is sure when, the bow and arrow was
invented. Like the spear, this deadly
technology spread around the world, and over time enabled the slaughter of
countless millions of animals. Of
course, with state of the art weaponry, well fed clans grew in number, conflicts
increased, and hunters increasingly had to also turn their weapons on strangers
who encroached into their territory.
A bloodless alternative to conflict was migration into lands
uninhabited by hominin competitors. Many
frontier regions introduced the ancestors to new species of prey, and clever
folks invented specialized technology for killing them. Joe Kane spent time with the Huaorani people
of the Amazon rainforest. Their armory
included spears and blowguns. Poison
darts would kill monkeys in the branches above, requiring the hunter to climb
up and retrieve them. Over time, lads
who did a lot of tree climbing developed odd-shaped feet. Their big toes bent outward, providing a
tighter grip.
Carleton Coon mentioned other tribes using different poisons
that relaxed the muscles of monkeys, so they would fall from the trees. No climbing needed. Pygmy poisons were a potion made from ten
different plants, beetle larvae, and snake venom. They paralyzed muscles and stopped the
heart. In Japan, the Ainu built booby
traps, in which deer tripped on a cord, and a bow shot a poison tipped arrow
into the animal.
When marine mammals were speared, their corpses often sank
into deep waters, never to be retrieved and consumed. The solution was to carve barbed detachable
harpoon heads which would not pull out of the animal’s flesh. The embedded head was attached to a cord
linked to the hunter above. When the
dead animal sank, it could then be retrieved and invited to lunch.
Innovation also led to the use of rock-throwing slings,
bolas, hunting nets, traps, and on and on.
You could fill a book on this subject, and Alfred Crosby did, covering
the entire spectrum from rocks to nuclear weapons. Humans are remarkably creative when it comes
to devising an endless stream of new and improved systems for killing things. It’s been a nonstop arms race.
The wheels of innovation spin faster when populations grow,
and become able to support more and more nerdy specialists. Also, trade with other regions brings distant
groups into contact, where they are exposed to the gizmos and ideas from other cultures,
and this can greatly stimulate the imaginations of anxious nerds. The velocity of change in my lifetime has
been dizzying, impossible to keep up with.
Craig Dilworth described what he called the Vicious Circle
Principle (VCP), a cycle in which (1) scarcity spurred technological innovation,
(2) innovation increased access to more resources, (3) more resources increased
consumption, (4) increased consumption fueled population growth, (5) population
growth led to resource depletion, and (6) resource depletion led to scarcity
once again.
The VCP cycle keeps repeating, each time ratcheting up the
impact, until it eventually slams into firm resource limits, or chokes to death
on its own pollution. Some
hunter-gatherer cultures managed to survive into recent times in a low impact
manner — until the radicalized VCP mob barged into their world via loggers,
miners, missionaries, and so on.
Dilworth noted that, from its beginning, technological
development has degraded ecological sustainability. Should we be proud of our legendary wizardry? Species that don’t manufacture tools, like
chimps, never experience this predicament.
Our current technological utopia, swarming with billions of hominins,
continues to work tirelessly to destroy the ecological basis upon which it
depends, a one-way dead-end path. How
smart is that?
Evolution is brilliant!
When predators are free to perform their natural ecosystem services, their
prey do not experience population outbursts.
Chimps make no effort to exterminate the big cats that prey on them,
consequently there are not seven billion chimps pounding the stuffing out of
the planet. The sacred dance of predator
and prey works beautifully until it gets blindsided by technological
innovation. Technology improved our
abilities at offence (killing game) as well as defense (exterminating competing
predators). Balance got blown out of the
water.
Dilworth mentioned that by 200 B.C. the leopards and lions of
Greece, and along the coast of the Near East, were gone. Several centuries later, tigers no longer
survived in northern Persia and Mesopotamia.
Predator extermination is a standard process in cultures that enslave
domesticated animals. Today, few wild
high-level predators survive in most of the civilized world.
Environmentalists tend to focus their campaigns primarily on problems
related to modern technology, because they think it’s especially terrible. Dilworth’s VCP sees all technology as
dangerous and unnecessary. Across Eurasia and the Americas, megafauna
extinctions surged between 10,000 and 30,000 years ago — in the Stone Age,
prior to agriculture and civilization, when fewer than ten million humans likely
wandered the Earth. It was an enormous
ecological holocaust that our culture has largely swept under the rug. Today, few consumers wake up screaming from
nightmares about the bloody extermination of mastodons, saber-tooth cats, or
woolly rhinos by high-tech hunters. We
are also careful not to think about the mass extinctions happening right now,
as we pedal to work.
The bottom line for Dilworth is that if technological
development was truly wisdom-driven, intelligent, and beneficial, it would not
have transformed the planet’s healthy genuinely sustainable wild ecosystems
into toxic devastated wastelands, depleted countless precious resources, and
sabotaged the climate. Why do we
continue proudly teaching children about our magnificent big brains and the
wonders of progress? The good news is that
the VCP cycle is unsustainable, and will eventually blink out. What will be left when it does?
