The Human Tailbone (Coccyx)

These fused vertebrae are the only vestiges that are left of the tail that other mammals still use for balance, communication, and in some primates, as a prehensile limb. As our ancestors were learning to walk upright, their tail became useless, and it slowly disappeared. It has been suggested that the coccyx helps to anchor minor muscles and may support pelvic organs. However, there have been many well documented medical cases where the tailbone has been surgically removed with little or no adverse effects. There have been documented cases of infants born with tails, an extended version of the tailbone that is composed of extra vertebrae. There are no adverse health effects of such a tail, unless perhaps the child was born in the Dark Ages. In that case, the child and the mother, now considered witches, would?ve been killed instantly.

The Top Tornado: March 18, 1925

The Tri-State Tornado was by far the worst in U.S. history. It wreaked havoc for more than three hours. Records were set for both speed and path length. Tornado damage stretched from Reynolds, Iron, Madison, Bollinger, Cape Girardeau and Perry counties in Missouri, through Jackson, Williamson, Franklin, Hamilton, and White counties in Illinois and Posey, Gibson and Pike counties in Indiana. The worst devastation was in Illinois, where the town of Gorham was destroyed. In Murphysboro, 25 deaths occurred in three schools, with students crushed under falling brick and stone walls.
