The mouse stepped into the light—and found
A world of ash and opportunity.
The sky was gray, the temperature still wound
Down from the impact winter's dark decree,
But the sun returned, thin and pale at first,
Through the clearing dust—and where it fell
On bare and devastated ground, the worst
Of the dying was already past the spell
Of its killing—the dust was settling,
The acid rain was fading, and the first
Green shoots of fern were meddling
With the ash-soil—and the dispersed
And battered survivors looked around.
Four houses had survived the asteroid's judgment—
Four ancient lineages found
The post-extinction world, and from this lodgment
Built everything that followed.
Turtlos—
The patient one, Paraps' armored child—
Emerged from whatever river-dulled repose
Had kept her through the fire. She was mild
And unbothered, as she had always been,
For the turtle carries her own fortress
And requires little—a pond, a green
Leaf, a warming stone—the tortoise
Asks almost nothing of the world and gives
Almost nothing back except the proof
That the patient, the unambitious, the one who lives
On the minimum—outlasts the roof
Of every empire that the bold have built.
Cruros' children—the crocodilians,
The river-dwellers who had spilt
No energy on civilizations
But had simply waited in the shallows,
Cold-blooded, patient, eating when the river
Brought them food and fasting in the fallows
When it didn't—the crocodile's liver
Processed the nothing of the impact winter
With the same indifference it processed
The plenty of the Cretaceous—the splinter
Of Cruros' once-great house, the rest
Had perished long ago, but the crocodile
Remained, unchanged, unhurried, unafraid,
The oldest living strategy of guile:
Do nothing, slowly, and outlast the blade.
Neornis—the crown birds, Archaeos'
Line refined and winnowed through the fire—
The feathered dinosaurs whose chaos
Of the impact winter tested higher
Than any trial before: the seed-eaters survived,
The ground-nesters, the small and flexible
Who ate what the darkness contrived
To leave behind—the kernel, the indexical
And patient seed that lay in the soil
Through the winter, the hard-shelled capsule
Of the angiosperm's foresight and toil
That fed the bird when nothing else was rational.
And Mammos—the mouse, the heir of Cynos,
Of Theraps, of Pelyon, of Synaps—
The synapsid exile who had known those
Hundred and eighty million years of wraps
And smallness and the nighttime vigil—
Mammos looked at the empty Paleocene
And saw what the burrowing and the frugal
Nightlife had prepared him for: the clean
And open daylight of a world without
The dinosaur's great shadow overhead.
For the first time in the synapsid's devout
And patient history, no giant tread
Shook the ground above his burrow's ceiling—
No theropod jaw waited at the entrance—
The world was his, and the feeling
Of the open, uncontested expanse
Was the feeling of the exile returned:
The promised land, emptied by catastrophe,
Waiting for whoever had earned
The right to fill it—and the biography
Of the Cenozoic would be written
By the mouse who stepped into the light
And found it good—the world was smitten
Open, and the morning after the night
Was the longest morning in the synapsid's story.
Honor the survivors—turtle, crocodile,
Bird, and mammal—the four whose glory
Was not in conquest but in guile
And patience and the minimum of need:
They did not defeat the asteroid—
They merely lived through it, and the seed
Of every future world that was deployed
From the Paleocene forward
Grew from the ash they walked upon that morning.
