No. 29: Sep-Oct 1993
Over 70 years ago, paleontologist Henri Martin found horse teeth estimated to be 30,000 years old that showed clear signs of "crib biting." Crib biting occurs when captive horses, perhaps out of boredom, bite ropes, enclosure structures, and even rocks -- wild horses don't do this. The implication is that man domesticated the horse long before archeologists believed possible. The theory languished until recently, when Paul Bahn brought it out of limbo. He has now found additional teeth showing more evidence of crib biting. Bahn maintains that man may have been riding the horse for 100,000 years!
