Robert Gross Book order

A Nobel Prize winning scientist discovers that the extinction of the dinosaurs was caused by a DNA sequence triggered by global warming sixty million years ago. He now finds that the identical gene in recently extinct and endangered species is becoming active in human beings. He theorizes that current changes in the earth's environment have again triggered the DNA sequence to activity, but is murdered before he can present his findings. While trying to salvage the scientist's research; his assistant and his best friend are hunted across the mountains of western Mongolia by men willing to trade humanity's future for power and money.
