OUT OF AFRICA: Researchers find Americans set their thermostat to match African environmental temperatures. “They compared the averages for homes in the U.S. with their cell data and found that people in the U.S. set the environmental conditions inside their homes in a way that very nearly matches environmental conditions in western Kenya and other parts of eastern Africa. They noted that conditions in Kenya also tend to be quite dry, similar to the U.S. They further noted that Kenya and nearby areas are believed to be the places where modern humans first appeared on the planet. They conclude by suggesting that modern humans are setting their thermostats to give them roughly the same climate they were exposed to during the period when they had no control over the weather. It is apparently the climate in which we are still most comfortable.”
