Pandorans

Pandoran life is four-limbed and tri-optic. When the dominant species left the dying planet, primitive animals with beaks and dorsal fins continued to adapt to the changing environment. Some became bipedal savages with crossbows, knives and tomahawks, who kill the Betan, Fidelio. Thus, intelligence evolved twice and the original species still visits although not while Chinook is there.

The Chinook crew continues to search through space for a species that has contact with the Others. The Avatar could have been a series.
