archedictyon (s) (noun), archedictyons (pl)
The name given to a hypothetical scheme of wing venation proposed for the very first winged insect: Archedictyon is based on a combination of speculation and fossil data. Since all winged insects are believed to have evolved from a common ancestor, the archedictyon represents the "template" that has been modified (and streamlined) by natural selection for 200 million years.

According to current dogma, the archedictyon contained 6-8 longitudinal veins.
