A child inherits features from its Ma
and Pa—appearance, weakness, talents, voice,
a plethora of details—not by choice,
but by the writing of genetic law.
Gametocytes contain a written text
which, sequenced in a 3-D alphabet,
describes the parents’ features. It’s reset,
and mixed, and carried to the next,
passing down the line a usable description. 
Data heritance, the basis of relation,
stems directly from the act of gene transcription;
parentage is DNA communication,
sending cell-to-cell a physical inscription. 
Reproduction copies written information.

Darwinian selection operates
through time. A given organism vies
for finite mates and food until it dies,
its name erased unless it procreates.
But if it does, its genome iterates
again within its offspring as each tries
in turn to reproduce. Mutations rise
by chance; each winning one accumulates,
boosting fitness of the total population.
Cycles of repeated, random introduction
of selectable genetic information
by mutation (even boosted by induction)
can’t complete within a single generation.
Evolution presupposes reproduction.
