memories

bacteria use CRISPR with CAS9
to fend off phages that they've seen before
encoded in their own genetic line
remembrances of the ongoing war
a selfish meme, intent to multiply
applies selective pressures on its host
which counters, if it isn't gonna die
a rational response, that needs no ghost
immunity requires a memory
to store a gallery of rogues and find
a complement to an old enemy
a smart riposte need not imply a mind
darwinians show 'how' but never 'why'
Life needs no grand Designer from on High
