While commonly thought to be incredibly dumb, it appears sheep may have been seriously misunderstood creatures. New research indicates sheep are far more intelligent than previously thought. Scientists at the University of Cambridge have found that the creatures have the brainpower to equal rodents, monkeys and, in some tests, even humans. The results suggest that sheep have relatively advanced learning capabilities, are adaptable, can map out their surroundings mentally and may even be able to plan ahead.
Researchers at the Texas Department of Highways in Fort Worth determined the cow population of the U.S. burps some 50 million tons of valuable hydrocarbons into the atmosphere each year. The accumulated burps of ten average cows could keep a small house adequately heated and its stove operating for a year.
