Praying Mantis
I caught this female mantis looking at me with suspicion or maybe fear. Why? Because the second photo shows her full of eggs. She did not have to worry about me, as I welcome her babies and their preying on other insects that are pests. (Shouldn't they be called "preying" mantis, rather than "praying?") Click to enlarge.

Tool Mistreatment
Tools have been of
tremendous benefit to humans. From the early use of stone tools
(dating back millions of years... even before humans arrived on the
scene) to the latest artificial intelligence (AI) machines, tools
have enabled us to extend our senses and multiply our physical
capabilities far beyond what nature gave us. Those first stone tools
brought our ancestors powerful new ways to smash nuts to get at their
interior, to cut up meat, to clean animal hides for clothing, and
even to fashion other tools.
When those ancestors
subsequently learned how to make metal tools, their capabilities
dramatically expanded. The later invention of telescopes and
microscopes extended our visual capacity out to the stars and into
the interior of biological cells. The list is limitless. It extends
all the way to today's computers that bring us almost unimaginably
powerful capabilities—possibly the most impressive of which is AI.
Human culture would
likely have remained on a par with chimpanzees, had we not been able
to create this increasingly complex and powerful lineage of tools. A
fascinating question that is often posed is how our big brain and our
fantastic tools are causally connected. Can we attribute the
evolution of our wonderful tools to our capacious cranium, or did our
increasingly sophisticated tools demand a bigger brain to use them?
It's sort of a chicken-and-egg conundrum. Whatever the answer, modern
humans certainly depend on and benefit from our many kinds of tools.
Tools are a form of
technology. The definition of a tool is traditionally considered to
be a hand-held device, used for a specific type of occupation. In
contrast, our modern tools are usually thought of as a form of
technology—a word that generally describes machinery or equipment
developed from or for scientific purposes. With these definitions, we
can see that those primitive hand-held tools gradually morphed into
various forms of technology. (Interestingly, the root of the word
technology is the Greek word tekhnologle, which means “the
systematic creation from art and/or craft.” This craft process
seems to me to be exactly how the early stone tools came about.)
Unfortunately, tools and
technology have also had a dark side—from the first stone hammer to
the latest AI machine. Tools seem to have invited mistreatment from
their very beginnings. The same rock that was used to crack a nut
also soon got used to crack a human skull. Sharp flaked stone tools
that allowed our ancestors to cut up a gazelle also got used as a
weapon to cut up other humans. Those primitive metal knives cut meat
better than stone, but soon saw use in warfare. And so it went,
throughout our evolution.
A current mistreatment of
a high-tech tool that billions of people have enjoyed
using—Facebook—is causing all kinds of trouble for many people.
Facebook is valued for its ability to keep people in instant and
handy touch with each other, but there's a dark side to its use that
is emerging. Commercial interests use big data algorithms to
determine intimate behaviors of Facebook users and then entice them
to buy billions of dollars worth of stuff they otherwise would not
have bought—without those targeted ads.
Multinational actors use
the same intimate data to manipulate people's behaviors through the
use of fake news and other biased misinformation. Facebook, Google,
Amazon, and other online businesses all exploit the power of
AI—ostensibly to offer us convenience, but also to amass huge
amounts of money by swaying our choices. And of course, many
technologists today worry about the future dangers of AI robots—which
some fear will either eliminate many current forms of employment or
even enslave their creators, us humans.
I am not equipped to
explain why it is that Homo sapiens is such a brilliant
creator of so many wonderful tools that make our lives so pleasant,
but then also get used as one form of weapon or another—weapons
which make so many lives miserable, or even terminate them.
Philosophers and pious people have pondered and debated that issue
for millennia. They have offered many diverse explanations—and most
of those explanations clash with each other.
Whatever the cause of
human behavior that leads us to mistreat our tools, there certainly
are countless examples of how we've perpetually done it. One factor
is that we seem to be suckers for the latest technology. Show me a
new, convenient and efficacious tool, and I'll want one. Tell me
about an attractive technology that's about to be offered, I'll want
one. Our initial intentions are rarely wicked; we simply focus on the
advantages, and thus we enthusiastically pursue the new tool.
But sooner—rather than
later—it seems that someone will find a way to mistreat the new
tool; even if they don't deliberately do so. Is it greed? Laziness?
Merciless competition? Seeking power over others? Or is it largely
due to the fact that we just move too fast, and can't seem to pause
and exercise a little precaution? I suppose it's all of these and
more.
Yes,
tool mistreatment is an ancient bad habit of humans. It's caused
untold suffering. And it doesn't appear that we are in the process of
reining ourselves in. The scary part is the fact that our tools have
become so powerful that their misuse can do damage beyond our
control.

Computer Bug
While typing one night, this guy crawled across my computer. I have no idea what it is. It was less than one-quarter inch (about half a centimeter) long. The top photo shows his eye better and the bottom photo shows his body better. Click to enlarge.

Coping With Copperheads—Part 2
So, might we find a way
to allow and encourage snakes to assume the duties we once assigned
to cats? If we had no cat, I believe resident snakes would be
thankful, because cats perceive snakes to be an enemy. I've watched
our cats harass a snake and even kill baby snakes. This animosity
makes some sense, given that cats and snakes prey upon many of the
same critters. They are in competition and the natural instinct is to
eliminate your rival.
Most of our snakes are
harmless to humans. We have black racers, milk snakes, ring snakes,
garter snakes, etc. But there is one species that puts fear into the
hearts of humans in these parts: the copperhead. It's
poisonous. It's venom is potent. Most of our neighbors who've lived
here all their lives regard copperheads as “nasty,” and will
quickly kill one with no remorse at all. I have seen a few of them
around here over the years, and have quickly retreated, when I spot
one. They can be aggressive and appear very threatening. They know
that they possess a potent weapon.
So, if we choose to forgo
getting another cat, while hoping that snakes will do the job we need
done, what do we do about those copperheads? Is it ethical to
encourage the presence of black snakes, while attempting to eradicate
a copperhead? Can we learn to cope with copperheads?
In an attempt to answer
some of these questions, I once again turned to the vast resources of
the internet. The copperhead's scientific name is Agkistrodon
contortrix. It is a pit viper (like its more formidable cousin
the rattlesnake), which means that it has two heat-sensing pits
located between its eyes and its nostrils. I love its alternative
names: chunkhead, dry-land moccasin, highland moccasin, pilot snake,
red snake, and death adder. (Yikes to that last one!) They inhabit
rock outcroppings, wood piles, and compost piles. That last place is
where I consistently see one. When I go to turn the compost piles and
throw back the tarp covering them, I very often bring to the light of
day a copperhead sitting imperiously atop the pile, disturbed that I
have blown its cover, and daring me to advance. I then proceed to
delicately shoo it away, to let me continue my work.
Copperheads are one of
the few snake species that give birth (in late summer) to live
babies, rather than deposit eggs that later hatch. The mother
incubates the eggs inside her body and then releases up to 14
squiggly babies—each one some 8-10 inches (20-25 cm) long. They are
mostly nocturnal—preferring to lay around during the day and hunt
at night. That helps to make encounters rare, as we humans tend to be
active in the day and lay around at night.
Unlike rattlesnakes,
copperhead bites are typically not fatal. In fact, the bigger
problem, if you get bit, is that their venom can cause local tissue
destruction, where secondary infection can set in. The greatest
number of snake bites in the US is from copperheads. That said, one
of these snakes would prefer to escape, when it encounters a human.
It is only when they feel cornered that they will strike out. So
there's no need for me to regard a copperhead as a perennial
enemy—only if I blunder upon one, unmindfully. And mindfulness is
an attribute that I have learned goes a long way toward making one's
life in the woods safer and more enjoyable.
So,
if copperhead snakes behave themselves—or, rather, if we stay
mindful and don't stumble heedlessly into their habitat—and we can
encourage other harmless snakes to proliferate, will our serpent
friends fulfill the function of our past cats? The serpents come at no
financial cost, are natural inhabitants around here, and already may
be in balance with other critters. Time will tell. We will hold off
on acquiring another cat and see how this experiment plays out. Maybe
I could even learn to welcome a snake cuddling up on my lap.

Coping With Copperheads—Part 1
In a previous blog
(“Failing Feline,” posted on 8 August) I reported that our aging
cat died recently. As he was slowly wasting away, we discussed how
and when to find another feline to replace him. For all of our more
than three decades of life here in the woods we've had a cat, for a
couple of reasons: First, I like a cat that curls up on my lap,
forming itself into a warm, fuzzy ball, especially on cold winter
nights. Second, a cat can be a useful control on rabbits and rodents.
Our garden has been partially protected by resident cats over the
years.
But to be honest, cats
also have a couple of disadvantages for us. The biggest problem is
their propensity to kill songbirds. We've done our best to discourage
their predatory action against our feathered friends (primarily by
keeping our cat indoors during the day), but we still lose half a
dozen birds each year. Another problem is expense. Veterinary bills
can get very pricey these days—especially if you spay or neuter the
cat, or if you have the bad luck of acquiring one whose genes promote
various diseases.
Then there's the issue of
acclimating and training a new cat to be a good citizen in the
household. That's another factor that we have little control over,
when we acquire a cat. Will it be a good mouser? Will it ignore mice
and go after birds? Will it care at all to curl up in my lap? Cats
for us are not mere cute pets. They have a job to do—just as any
member of the family does. To what extent would a new cat fulfill its
duties?
As I pondered the
question, I began to wonder if we really needed a cat. What if
a new cat scorned all these duties? There goes a primary reason for
having one. We might incur several cat-related expenses for nothing.
So, is there an
alternative? It occurred to me, as I thought about it, that snakes
provide many of the same services that a cat does. Snakes prey on
rodents and large insects like caterpillars, as well as birds. Oh oh
to that last one! Overall, it seems that snakes can offer many of the
same benefits that cats do; and they come with no vet bills or
commercial food to buy. Furthermore, they are a natural resident of
the area. In that sense cats (as well as we humans) are an invasive
species!
Hmmm... could snakes do
the job (for free) that cats have done for us in the past? During our
first few years here, I possessed the typical human animosity towards
snakes. We humans have a deep evolutionary repulsion of snakes. The
book of Genesis biases many us, by blaming the snake for our eviction
from the Garden of Eden. That predilection is most likely inherited
from even more distant ancestors of ours.
Furthermore, it's hard
not to flinch when we humans spot a snake. They seem to be the
essence of a threat. They slither. It almost makes one's skin crawl
to observe that sneaky slink. And only the most foolish or brave
person would dare to touch a snake! In short, an undulating serpent
appears revolting.
Or so I thought, for many
years. Gradually, however, I've come to accept—and even
appreciate—snakes. I've never had one attempt to lure me into evil,
by talking me into biting into an apple. I've never had one bite
me—let alone even really threaten me. Over the years I've learned
to understand where a snake might be residing, and thus not to
blunder into its territory. (In a similar vein I've learned the
habits of stinging wasps and bees, and how to avoid invading their
space.) In many ways, life out here has been a series of lessons of
how to share space with creatures that I once deemed pests and could
only imagine them as foes. I may not have yet come to see them as
cuddly buddies, but I can appreciate how they fulfill a role in this
small ecosystem.
More on snakes next
time...
