Rhyniognatha hirstiA Poem byFossil evidence indicates that flight evolved as soon as life left the seas.
Four hundred and eight
million years or more ago, these mandibled
arthropods were alive. Left years to languish in the
fossil drawer, unearthed again, just crushed
remains survive. These natives of what would
be Aberdeen, by nearly thirty million
years, predate the oldest bugs that anyone
had seen -- New York’s silverfish must
now abdicate. Their body shape seems to
exemplify what we today can still
identify -- ancestors of our modern
dragonfly -- and that they had four wings
we can imply. What does it matter? What’s it signify? Once life emerged from seas,
it learned to fly.
