The Outer Limits - Season 3 Episode 12 Double Helix

Since Dr. Martin Nodel is the most brilliant geneticist in the world, the students and staff at the university are willing to put up with a few eccentricities -- unlike his son Paul, who gets impatient with his father's behavior. However, Dr. Nodel's behavior goes beyond eccentric after he unveils his research into introns, mysterious genetic material which he believes hold the code for future evolution. After a successful animal test, Nodel secretly tries the formula on himself, with amazing and disturbing results. As his intelligence begins to grow, so do scales on his hands, strange markings on his body, and a mysterious hole in his back. And he seems to be getting instinctive messages telling him to bring 'subjects' to a remote wilderness location. When he arrives there, accompanied by six students including Paul and his girlfriend, he finds a group of heavily armed soldiers and the key to unlocking a mystery that goes far beyond human science.
