I post the poem again to make the connection more clear! :)
The Conjugation of the Paramecium
This has nothing
to do with
propagating
The species
is continued
as so many are
(among the smaller creatures)
by fission
(and this species
is very small
next in order to
the amoeba, the beginning one)
The paramecium
achieves, then,
immortality
by dividing
But when
the paramecium
desires renewal
strength another joy
this is what
the paramecium does:
The paramecium
lies down beside
another paramecium
Slowly inexplicably
the exchange
takes place
in which
some bits
of the nucleus of each
are exchanged
for some bits
of the nucleus
of the other
This is called
the conjugation of the paramecium.
