December 10th: Trilobites
You get a lot of ‘stuff’ at Christmas, don’t you? It’s different kinds of stuff, yes; But a lot
of ‘stuff’, overall. Some of the stuff is very obviously Christmas stuff, some
of the stuff is everyday stuff that is just receiving more attention than usual
because it’s Christmas.
For example, cheap decorations (tinsel, baubles etc.) and
red bobble hats = Christmas stuff. Vegetables, nuts and winter clothing =
regular stuff that is rendered festive by the Christmas period. And this first
part of this piece has the word ‘stuff’ in it far too much, doesn’t it?
That’s sort of the point though. What defines ‘stuff’? It
could be argued that it’s the sort of thing that is encountered often and/or in
large enough quantities that it breaches the point where the human mind finds
it necessary to specify it in any detail. And we encounter this sort of thing
often at Christmas.
The brain is quite good at filtering and generalising when
presented with too much stimuli. “What did you get for Christmas?” “You know,
stuff” (Pairs of socks/pants, deodorant, slippers if you’re of a certain age
group). Those chocolates you get in the
big tins, the ones that have nougat or that hard crystallised stuff which nobody
can identify, they’re generally lumped together as ‘leftover stuff’. And so on.
Scientifically, stuff has a different meaning. Dark
Matter, for example, is ‘stuff’ because it is impossible to specify. There’s
lots of it (supposedly), but scientists are very keen to actually see the
bloody stuff (although by definition, that should
be impossible). However, scientifically speaking, it’s rare for a species
to be classified as ‘stuff’.
If any has managed this bizarre achievement, it’s the Trilobite. One of the most
abundant fossil types you’ll find, it’s more of a species type than an
individual species. Trilobites arrived on the scene, life-on-Earth-wise over half a billion years ago,
and hung around for at least a quarter billion years. In comparison, humans are
just at the point where we’ve crawled out of the sea.
Trilobites. They
spread everywhere.
They swam, they hunted, they filtered, they
grazed, they may well have dressed up like bats and fought crime (although
this is doubtful as this was long before the existence of bats, or crime as we
know it, probably).
Then they died out, as things often do. With their
exoskeletons and widespread antics, they left durable remains
everywhere, becoming the fossil equivalent of a pair of socks at Christmas; not
something you’re unhappy about getting, but it will probably be thrown aside
while you seek out the ‘cool’ stuff.
But there will come a time when you need the socks, and
while that games console is riddled with bugs and just causes frustration and
headaches, the socks are always reliable and useful. Trilobites are a bit like
that. Despite the fact that most lay people would think of them as fossil
‘stuff’ (if they think of them at all), trilobites have taught us an amazing number of things.
Or ‘stuff’, if you prefer.
Trilobites and socks at Christmas; generally ignored, but
we’d be complaining if they weren’t around. We’re so ungrateful as a species.
