Random cool story

So for those of you that have fruit fly cultures or do experiments with fruit flies you know what I'm talking about. Some scientists were doing experiments with fruit fly generations and learned behaviors so they let numurous generations of fruit flies live in an upside down jar on a table. One day they decided to remove the jar to see what happens. The flies still flew in an exact pattern of the jar. Eventually these flies died and had offspring. Their offspring still flew in the pattern of the jar. Pretty sick huh?
