Prey
Science fiction never does the theory of evolution justice. Not that it hasn't tried, though. In "Prey" (1998), a Bio-Anthropologist named Sloan Parker (Debra Messing) discovers evidence of a new species of hominid that has evolved separately from Homo sapiens. They're called the "Dominants." They are, so the series says, to us what we were to neanderthals: a new and improved breed. They are organized like a secret society, and they brainwash their own children into lethal killers. Their goal is to displace us, like we displaced the neanderthals. And no, none of this makes any scientific sense at all.
Firstly, the idea that humans were directly responsible for the neanderthals' extinction is not given much credibility in modern anthropology. Scientists look to other factors like disease and the environment to explain the disappearance of Homo neanderthalensis. They weren't picked off one by one by modern humans with more advanced technology. Rather, nature selected against their survival, and modern humans moved in after they were gone.
The idea that another species of human has evolved to occupy our same ecological niche and is now competing with us is alluring. Making the enemy an alternately-evolved human immediately meant that the Dominants of "Prey" were complex and layered. Adam Storke played the token Dominant teammate of the good guys, a Dominant who broke his mental conditioning and worked with the heroes to stop the extermination of mankind.
The science is silly: Dominants are superbeings, with superior strength, intellect, mental abilities similar to ESP, and the females have four uteruses. Of course, the Dominants have access to advanced genetic engineering, so some of these traits maybe artificial, but it begs the question of how such a species as humans would have evolved in the first place if evolution is capable of producing superbeings. Evolution, of course, does not produce superbeings, much less ones that can blend in unsuspectingly among the populace despite all of them supposedly sharing a more recent common ancestor than with any other human groups (there are Caucasian Dominants and African-American Dominants, and no explanation is given as to how they evolved these appearances when they are all supposed to have been from one abandoned village in Mexico). It's probably a good thing that they didn't cast Latino actors exclusively as the inhuman Dominants, as that would have had some very unfortunate implications. Nonetheless, "Prey" presents ancient mysteries such as a mysterious stone pillar, destructive nanite technology, and genetic engineering by superhumans, all with some significance to the overall plot. Unfortunately, in 13 episodes, it never had a chance to wrap up half the plot threads it started, and the episodic nature of the storylines felt dated when it aired. The creep-factor is strong, and the acting is top-notch. Vincent Ventresca, of "The Invisible Man," plays Sloane's geeky lab partner, and Larry Drake appears as the shadowy Dr. Atwood, a government scientist who knows more about the Dominants than he's letting on.
"Prey" is worth a watch, at least for a chuckle at the bad science, but it was no "First Wave."
