The Eon Staircase

Dr. Robert Porter is a gifted biochemical scientist who obtained a research grant from the world's largest prescription drug producer, Globelink Pharmaceutical. His contract finances an investigation to develop a new class of drugs designed to capitalize on an expanding market for anti-depressants. Nearing the end of their sponsorship, the team makes an accidental discovery that compels them to divert from their experimentation and press into an unexplored realm of DNA biochemistry. For over 300,000 years in the fossil record, Homo sapiens have existed. Yet, the written history of our species is just a fraction of that period, say 5,000 years. For decades, scientists have searched in vain for the specific point that man evolved into his intellectual self. Some call this the search for the Missing Link. Come now, and step down the Eon Staircase. Descend far into the past for a fictional answer to this timeless mystery.
