In answer to a distress call, the Enterprise comes across a pair of three-centuries-old earth colonies. One is comprised of the Bringoldis, descendants of the original Irish colonists. The other is populated by the look-a-like Mariposans, a race of clones who desperately crave new genetic material. Originally titled Send in the Clones, "Up the Long Ladder" was written by Melinda M. Snodgrass, and first aired May 27, 1989. ~ Hal Erickson, Rovi
