### I would say paralog, since the structures arose by duplication of genes
or gene families within a species, and then persisted through hundreds of
speciation events. Analog is actually also a good term, if perhaps less
sciency-sounding and may imply an incorrect evolutionary mechanism. Homolog
is also appropriate, although more general than paralog.
