Origins of Avis Sapiens

Where did birbs come from? 

The birbs themselves don't know. Their archaeological findings haven't given them much insight to their evolutionary history. 


What the birbs don't know is that they are scions of homo sapiens, who died out long ago. Humanity (or a decently-close evolution of it) managed to avoid 'black marble' events (like the development of nuclear weapons) from dooming their own species, but eventually one of their sciences led to them dooming their own solar system. In a forlorn attempt to preserve their legacy, some humans (or neo-humans) flung relics of Earth throughout spacetime. One such relic landed on the planet that became Birb-Earth (where the birbs live). 

The life on Birb-Earth comes from the genetic material transplanted to Birb-Earth by that relic. This is also the origin of the nanomachines that permeate the planet's atmosphere (the same nanomachines that birbs unconsciously utilize when they work their 'magic'). It is also the origin of Violetviolet Fulgurite.fulgurite.
