Save your­self, serve your­self
World serves its own needs, lis­ten to your heart bleed
Dummy with the rap­ture and the revered in the right
You vit­ri­olic, patri­ot­ic, slam fight, bright light
Feeling pret­ty psy­ched
It’s the end of the world as we know it

~R.E.M., It’s the End of the World as We Know It (And I Feel Fine)


I have a friend who is tru­ly con­vinced that cli­mate change means our chil­dren will not die of old age. She says human­i­ty is one pan­dem­ic away from total destruc­tion, adding if some white man with a small penis doesn’t release the nuclear bombs first. Her life mot­to? We are all doomed. So bleak. But maybe she’s right. Maybe it is the end of the world.

But as Michael Stipe reminds us, it’s only the end of the world as we know it. It’s nev­er the actu­al end of the world. When I real­ly start to despair for human­i­ty, I am soothed by the sto­ry of evo­lu­tion. You see, evo­lu­tion has taught us some­thing cru­cial: life adapts and endures. 

The sto­ry of evo­lu­tion is not mere­ly a sci­en­tif­ic time­line, but a spir­i­tu­al nar­ra­tive, a poem writ­ten across eons. Every end­ing is a new begin­ning, a climb from mol­e­cules to sen­tient minds, from ocean sludge to sail­ing ves­sels, from silence to sym­phonies, from swirling cos­mic dust to Harry Potter and facial recog­ni­tion soft­ware and pick­le­ball and air fryers. 

Our DNA is a star­dust muse­um of every­thing that came before. Species don’t adapt because it’s easy; they adapt because they must. In this, evo­lu­tion mir­rors our own lives. When we resist change, we become trapped. When we accept it, we evolve.

Four and a half bil­lion years ago, Earth was a hot, molten sphere, noth­ing but chaos and gas. Lightning struck the oceans, and from that pri­mor­dial soup of chem­i­cals, some­thing mirac­u­lous hap­pened. Simple mol­e­cules assem­bled into life, lay­ing the ground­work for the 14 mil­lion species that would at some point call this blue mar­ble home.

About 3.5 bil­lion years ago, sin­gle cells learned to pho­to­syn­the­size. As a byprod­uct of pho­to­syn­the­sis, oxy­gen was pro­duced, accu­mu­lat­ing in the oceans and the atmos­phere. The so-called Great Oxygenation Event killed off many ancient forms of life, but it also opened the door to new pos­si­bil­i­ties. From every end­ing, a new beginning. 

Then came the Cambrian explo­sion, a burst of evo­lu­tion­ary cre­ativ­i­ty unmatched in the his­to­ry of life. In the seas, crea­tures devel­oped eyes, shells, and limbs. For mil­lions of years, swim­ming and slith­er­ing crea­tures grew extinct, then returned, bet­ter equipped to sur­vive the chang­ing land­scapes and atmosphere.

Some fish devel­oped lungs and limbs, enabling them to crawl onto land. Ferns and insects fol­lowed. Then came the dinosaurs, who ruled for the next 180 mil­lion years. 66 mil­lion years ago, an aster­oid six miles in diam­e­ter hit the Yucatan Peninsula and, just like that, 75% of the species on Earth disappeared. 

But the end­ing of the (non-aviary) dinosaurs was our begin­ning. Mammals, once small and timid, rose to fill the emp­ty spaces left by the dinosaurs. From prim­i­tive mam­mals, pri­mates emerged, then stood upright. We lost our tail and gained a life­time of back pain. We devel­oped not just tools and fire, but words and sto­ries, empa­thy and worry.

Our DNA is a star­dust muse­um of every­thing that came before. Species don’t adapt because it’s easy; they adapt because they must. In this, evo­lu­tion mir­rors our own lives. When we resist change, we become trapped. When we accept it, we evolve.

So we get bet­ter at being human. Or we deplete Mother Earth’s resources to our own extinc­tion. A shame, but ulti­mate­ly a blip in the sto­ry of our plan­et. When we imag­ine the end of human­i­ty, fear often fills the pic­ture. We see loss, silence, an abrupt van­ish­ing of all our sto­ries, our art, our laugh­ter. It feels unbear­able to think that every­thing we are might slip into noth­ing. And yet, if we look through the lens of evo­lu­tion, there is anoth­er way to see the end – not as an anni­hi­la­tion, but as a con­tin­u­a­tion of life’s bound­less cre­ativ­i­ty. The uni­verse wastes noth­ing. Our bones, our cities, and our his­to­ries will feed the soil of tomorrow. 

From our end­ing will grow a new begin­ning. Evolution reminds us that we are not the pin­na­cle of exis­tence, but a chap­ter in a much longer book. 

If it’s the end of the world as we know it? I feel fine.
