When taken together, they argued for the introduction of a unique genetic anomaly into the human genome during the Egyptian late Eighteenth Dynasty; the source was extraterrestrial. How does an international scientific effort resolved the situation by using a most unusual means for prosecuting a most unscrupulous task, time travel and murder?
