I was in Michigan for a Bio study trip
in 1999. I can't really recall what the study was, something with the
gestation of certain breeds of sheep on a farm? Anyway, the owner of
the farm that we were studying at came to meet with us – he was a
very kind man. He decided to bring us on a tour around the farm, to
get our bearings... and I remember there was one thing he said that I
kept with me beyond even the study we were conducting.
We were out in the fields where the
cows roamed, and he told us that, long ago, farmers found a certain
pattern among these animals. They found that each one of them had a
partner... but it wasn't a sexual partner, it was separate from them.
An entirely different cow. The two partners would eat together, sleep
together, mimic each others quirks, et cetera... the farmers found
that the cows made friends. Not multiple friends though, just one. A
partner that they would spend the rest of their time on this Earth
with.
And that was interesting to me, because
it's not really a normal thing among animals to make friends. And
when they do, you'd expect some, I don't know – some smart animal
to do it, like a monkey or a dolphin. Not a cow. You see, friendship
is a fairly abstract thought – a desire to copulate is natural
among all living things, because it continues the species. It
strengthens the big picture. But friendship – there's no big
picture to that. It's really a singular event, tied to the lifetimes
of only two members of a species. There's no biological, evolutionary
reason to keep friends – we just do.
However, those same farmers also
discovered another thing. They found that when they slaughtered one
of the cows, its partner would completely break down. It would stop
eating, spin in circles for hours, try to sleep for exorbitant
amounts of time – some cows even attempted to eat their own fecal
matter, or drive their heads into a wall over and over and over
again...
At first, the farmers thought that the
cows had been suffering from some sort of parasitic infection, but
found no traces of any such thing. Soon, however, they found it was
something else – the cows were trying to kill themselves. And now,
this was really interesting. Because unlike friendship, which
is completely benign to evolutionary process, suicide actually
impedes it. Suicide is a completely emotional construct – and it
was crazy, because at the time everyone thought that only humans
could consider such an abstract idea. And yet cows – cows, of all
things – could feel this way. And that's when psychologists started
thinking, well, maybe its not that suicide is an abstract concept,
per say, but rather the connection between the feeling of either
having someone to relate to, or being completely alone.
Every since that discovery, nearly all
farms have universally adopted killing both partners at the same
time, so neither cow has these symptoms. Whether this was out of
sympathy or that a mad cow makes bad beef, no one really knows.
