Baseball players reveal how humans evolved to throw so well. A catapult-like mechanism allows energy to be stored in shoulder and torso, a video study of pitchers reveals.
Although some primates occasionally throw objects, and with a fair degree of accuracy, only humans can routinely hurl projectiles with both speed and accuracy. Adult male chimpanzees can throw objects at speeds of around 30 kilometres per hour, but even a 12-year-old human can pitch a baseball three times faster than that
The Paleo Diet is a new food trend. There is little doubt that many modern humans eat too much sugar and processed foods. However, recent studies show that identifying a particular “paleo” diet is impossible. Researchers are just beginning to understand what ancient humans ate, and these recent studies show that grasses and grains have been part of the human diet for millions of years.

Late last month, the Missouri House started considering [a bill] that deviates in staggering ways. Instead of being quiet about its intent, it redefines science, provides a clearer definition of intelligent design than any of the idea's advocates ever have, and it mandates equal treatment of the two. In the process, it mangles things so badly that teachers would be prohibited from discussing Mendel's Laws.
