THE TIME CAPSULE
Since one million years had just passed by,
They, of the future, prepared to open, nigh,
The absolutely sealed container’s prize,
Of a capsule made so carefully that it did survive
Without damage, being totally impregnable
To any outside influence imaginable.
They expected to see, perhaps, some old relic,
But certainly nothing alive that could tell of it,
For it would be hard to imagine, even then,
That some organism could keep on going its ken
Over its course of a million years later,
Sealed inside this tight container,
Unable even to exchange energy’s spark,
This metabolism being the hallmark
Of life and all that quacked or quarked…
And, so, they did not at all expect something
In there that would be flapping its wings,
Gasping for air, or anything at all of life’s song,
Wondering what had taken so long.
Well, they were right and they were wrong,
For in the time capsule that was planted so long,
Several things had with it come along…
One was a plaque, of numbers low and high,
And containing some primes and pi,
Another, some essays of the future—
Some, like Austin’s, quite mature,
Along with maps and other items of the world
From those times when the oceans swirled;
But, the last, one perhaps not intended,
Was a microbe—an extremophile—
Laying there quite contented all the while!
Well, they soon laughed, loud and long,
For they were in between right and wrong
About what could survive from so long ago,
For, it was really walking mighty slow!

BACTERIA:
THE BACK DOOR TO OUR STOMACH’S CAFETERIA
AND THE INVINCIBLE RULERS OF THE EARTH
For two billion years in the Archaean world, bacteria
Were the only forms of life. Algae, or Cyanobacteria,
Learned to absorb water molecules, dining on hydrogen,
But releasing oxygen as waste; photosynthesis began.
The world began to slowly fill with “poisonous” oxygen,
But not right away, as it first combined with iron then,
Producing iron oxide that sank, that on the bottom lay,
In primitive seas, the world literally rusting away.
After 2 billion years, the atmosphere had some oxygen;
A new kind of cell arose. Some oxygen-using organisms
With organelles produced an energy much more efficient.
This was the endosymbiotic event of a mitochondrion
Which made complex life possible, by a liberation
Of energy from food, feeding on nutrients we take in.
We need them but they don’t need us, for without them
We couldn’t even live for two minutes.
They don’t even speak the same genetic language
As the cells in which they live.
These eukaryotes are old and unknown visitors
Within our homes who’ve stayed on for a billion years.
In another billion years they learned to form together
Into complex multicellular beings, yet, still this world
Of the small was to ever live on and rule the world.
At dinner, Louis Pasteur used a magnifying glass for
Searching for microbes in his food, until invited no more.
There are 100 quadrillion bacteria within us & upon us,
Ever grazing on our flesh and digesting our food bus.
The Earth is not our planet, but theirs; they let us live.
They even purify our water and keep the soil productive.
A single bacterial cell can generate 280,000 more a day.
They can also share information, taking a piece away
Of genetic code from any other any time. They swim
In a single gene pool—an invincible superorganism.
They live in caustic lakes, in Antarctica, in boiling mud,
And even thrive seven miles down in the Pacific Ocean;
In sulfuric acid, too, and in a 166-year-old bottle of beer,
And can even gorge themselves on plutonium nuclear.
Bacteria were yet alive in a sealed camera lens stowed
On the moon for two years, but they seemed a bit slowed.
Some were even found two thousand feet below the Earth
Dining on what’s in rocks, like iron, sulfur, and dirt.
Some frozen ones were even revived from the 3 million
Year-old permafrost of Siberia, and even one older than
The continents, was resuscitated, a 250 million-year-old
Bacterium that had been trapped in a salt deposit hold,
Two thousand feet underground in New Mexico, maybe.
