Star Trek’s Most Important Episode Originally Had Dust Mites Flying Tiny Airplanes

One of the most unappreciated members of any given Star Trek show is the science consultant. This is the guy who is in charge of making all of the crazy sci-fi adventures of our favorite characters sound relatively realistic. At the end of the day, that’s what separates this franchise from Star Wars, which explains its wildest plot points by simply saying that the Force moved in mysterious ways.

On one occasion, a scientific consultant effectively saved the most important episode of Star Trek: The Next Generation. After the rocky second season ended with a crappy clip show, Season 3 began with “Evolution,” a banger episode that proved that TNG was about to become must-see TV. The episode prominently featured nanites, futuristic machines straight out of our wildest sci-fi fantasies. But without consultant David Krieger, this episode wouldn’t have had nanites. Instead, it would have had dust mites flying tiny planes around the Enterprise!

Good Boys And Bad Science

For context, the plot of “Evolution” involved the Enterprise crew helping a cranky genius study a stellar explosion that happens every 196 years like clockwork. Meanwhile, teenage wunderkind Wesley Crusher was conducting experiments involving nanites, and he accidentally let a couple of the critters loose. Soon, they replicate and evolve, threatening the big experiment and everyone aboard the ship. The scientist clashes with the nanites, but Picard reaches a diplomatic solution by securing these new life forms their very own homeworld.

“Evolution” is an excellent episode, and it was written by Michael Piller, the man who ultimately became TNG’s showrunner and turned it into one of the best shows in television history. Plus, the nanites are one of the coolest creatures ever introduced into Star Trek. However, Star Trek science consultant David Krieger revealed on his personal website that this episode was nearly very different. According to him, the original pitch didn’t include nanites. Instead, it featured dust mites that gained intelligence and flew around the Enterprise in miniature aircraft.

A Shocking Development

Fortunately for all of us, Krieger found this idea deeply stupid. In fact, he claims that he laughed out loud when he read the original premise for the episode. Once he stopped chuckling, though, he spoke to the producers and firmly objected to the idea of dust mites turning into tiny flying gremlins. Instead, he proposed using nanites instead, which was a great call: not only are nanites based on actual scientific theories, but they looked far less goofy onscreen than flying dust mites ever would.

If David Krieger hadn’t stepped in and shut down the dust mite plot, “Evolution” would have joined the ranks of “Spock’s Brain” as one of the worst episodes in all of Star Trek history. Thanks to this science consultant’s intervention, though, this episode helped transform The Next Generation into what many fans consider the gold standard of the franchise. It also helped Michael Piller become showrunner, and he was so successful in the role that he would later help create both Deep Space Nine and Voyager. In that way, this humble consultant did more than save a single episode; he may have saved Star Trek as we know it!
