Arguments against cloning

I see my Brother in my bro-
ther, myself in her.
They are more similar to us than siblings:
I am watching ourselves grow up fifteen years later.
Incredulous, the way he cries like my brother, the way she
Smiles dumbly and sweetly, like watching something wonderfully
Gruesome like the migration of red pincers fidgeting across the beach.

I see my Brother in my bro-
ther. Nature has always been good at imitation and she got lazy
And plagiarised our algorithms, and even our names:
Here, meet yourself. I feel cruel with the diluted strands of bloodline
Grasped in my hands. Do I cut them? Or replicate them? Or

Try to swallow these progenies like a savage embryo?
Nature sure has gotten lazy, even the permutation did not change.
Favouritism, like a towering god, made him weepy
And her a cunning and terrible sister.

The crabs shuffled along. My Brother and I watched our bro-
ther with difficulty, and our sis-
ter with a little malice. If this was a world with clones
We should lock the seeds up and swallow them while we can.
