History has recorded ethics becoming a casualty of scientific progress on a disturbing number of occasions. Breakthroughs become twisted for violent applications, leading to terribly efficient warfare. Cloning is just one such example. While its beneficial application to the field of medicine is unquestionable, no one will soon forget the scourge of the Clone Wars.

The clone troopers introduced in that long conflict were crafted by the scientific geniuses of Kamino, aliens renowned for their genetic knowledge. The Kaminoan hatcheries used genetic material harvested from the host template, a bounty hunter named Jango Fett. This material was grown into thousands of soldiers inside glass-walled incubation wombs.

The Kaminoans employed growth acceleration techniques to effectively double the rate of clone development. Without such measures, it would take a full life-time to grow a mature clone. Their adult clones were ready for combat in less than a decade. Throughout a clone's growth, constant physical and mental training honed the warrior's skills. Unlike the mindless battle droid armies of the commerce guilds, clones could think creatively and operate much more independently.
