| Tauntauns: The trait observed is their fur thickness. Fur thickness ranges from 0 (no fur) to 10 (thick fur). The graph below shows directional selection over time. The average fur cover became thicker possibly due to more frigid temperatures. It is better to be on one extreme than the other. |  |
| Jawas: The trait observed is their eye brightness. Eye brightness ranges from 0 (dull eyes) to 10 (brightly glowing eyes). The graph below shows stabilizing selection over time. Jawas of average eye brightness became more common and Jawas of either dull eyes or extremely bright eyes became less common. This could possibly be due to a scenario in which dull eyed Jawas could not attract mates whereas Jawas with brightly glowing eyes may have attracted mate, but also attracted predators. Jawas with eyes of moderate brightness were still capable of attracting mates, but less likely to attract predators than bright eyed Jawas. It is better to be average than to be either extreme. |  |
| Gungans: The trait observed is their eye sight. Eye sight ranges from 0 (strong night-vision, poor day-vision) to 10 (strong day-vision, poor night-vision). The graph below shows disruptive selection over time. Gungans of average eye sight became less common and gungans of either strong night-vision and strong day-vision became more common. This could possibly be due to a scenario in which gungans with average vision could not compete with night-vision gungans at night nor could they compete with day-vision gungans during the day. In either case, the ability to hunt prey or detect predators would be selected against. It is better to be extreme than to be average. |  |
