(The name is derived from the local Afar language. Ardi means ground or floor; ramid means root; and kadabba means basal family ancestor. In accordance with the sometimes bizarre nomenclature of science, the younger creature now gets renamed Ardipithecus ramidus ramidus...
...that feathers originally arose to keep dinosaurs warm.

Says Padian: "They must have had a high basal metabolic rate to grow that fast. And I wouldn't be surprised if they had some sort of skin covering for insulation when they were small." Says Norell: "Even baby tyrannosaurs probably looked like this...

This can be done in an office with local anesthesia. Recurrence of small tumors treated this way is about 5 percent.

And in between, they suggest avoiding the sun during its peak intensity in the middle of the day. If you have to go outside, protect yourself with sunscreen and clothing.
