In an interview with Monsters and Critics at the end of July, Eureka writer and producer Jaime Paglia notes that there was a personal inspiration for the biosphere plot line:
Biosphere 2 was originally built to research and develop closed ecosystem technology for long term space exploration. The enclosed sealed structure had far more varied flora and fauna than the surrounding Arizona desert:
I think you might remember the Biosphere 2 project that was out there in Arizona and he was - my dad's a scientist, a medical doctor. And he was one of the primary consultants on that. So we have an episode that's about what does a biosphere in Eureka look like and what happens if some you have a missing persons case inside of the closed biosphere.
Inside was a rainforest, an 850 square meter ocean with a coral reef, a 450 square meter mangrove wetlands, a 1900 square meter savannah grassland, a 1400 square meter fog desert, a 2500 square meter agricultural system, a human habitat with living quarters and office, and a below-ground level technical facility. Heating and cooling water circulated through independent piping systems, and electrical power was supplied from a natural gas energy center through airtight penetrations.The system apparently suffered from unexpected fluctuations in carbon dioxide and oxygen levels during its first (and only complete) mission. There apparently was much personal conflict within the project, exacerbated by low oxygen levels and a calorie restricted diet.
I thought that the biosphere element of "What About Bob?" was pretty nifty. Sure, it's implausible that such a structure could be created underground (and that they would allow someone from outside to enter, even with a very thorough scrubbing) but it's well within the norms of the fantasy science of the show. And they got the interpersonal conflict bit right. The problem I had with the episode was with explanation of what happened to poor Bob.
You see, Bob was working on a genetic engineering project that unfortunately went wrong and ended up turning him into a sort of snake man. At EUREKA unscripted the writers explain their inspiration:
And just how did we settle on our snake man? One of our main inspirations for a story involving human mutagenics was David Cronenberg’s brilliant movie, THE FLY. Of course, we also love comic books and comic book movies, so The Lizard, one of SPIDER-MAN’s grooviest villains, also inspired us.So Bob's a monster-of-the-week. Unlike The Lizard, he didn't ingest a serum developed from reptile DNA to stimulate limb regrowth, and unlike the scientist in The Fly, he didn't accidentally become melded with a fly in a tragic teleporter accident. Instead, he's turning into a snake as an unexpected side effect of "mutagenic wavelengths" of light that alter the biosystem's water supply.
That wouldn't have bugged me (much) if they hadn't turned to awful Star Trek science for the "technical" explanation. I'm thinking specifically of the Star Trek: The Next Generation episode "Genesis", where, by a very unlikely series of events, a disease emerges that activates "dormant genes" and "latent introns". The result is that the crew of the Enterprise "de-evolves" into other animals: Lieutenant Barclay becomes a spider, Worf turns into a reptile, and Captain Picard into a lemur. The whole thing makes no sense at all from a biological perspective. Humans don't have a bunch of "reptile" genes that became "dormant" during evolution. Instead, many evolutionary changes are likely due to differences in gene expression during embryonic development (see "What is Evo-Devo?" and "Regulating Evolution: How Gene Switches Make Life"). While babies are occasionally born with atavistic anatomical characteristics, such as tails, that doesn't mean they have turned into monkeys.
But let's say genes could be activated in a pattern more reminiscent of our ancestral forms. Doing so in an adult wouldn't change a human into another animal - although it might cause a tumor. And even if it were possible to "de-evolve", humans wouldn't turn into spiders or snakes, because those animals are not our ancestors. Basically, the idea of "de-evolution into other animals" is really bad biology - and that's unfortunately the explanation for Bob's reptilian condition. As mathematician and all-around-science-guy Nathan Stark explains, it's "evolution in reverse" caused by the activation of his "dormant reptile DNA" that caused his change into a snake-man. I would have liked it better if Bob had been hit with a super form of Ichthiosis vulgaris, as suggested by Allison Blake, or maybe a mutated bioengineered retrovirus. At least those would have been a bit plausible.**
Watch the Eureka episode "What About Bob?" at Hulu.com.
* Note to Eureka's producers: tonight's episode had way too much advertising of Degree super-duper antiperspirant for men. When the ads came up - again - during the second commercial break, we almost changed the channel. And next week I'll probably tape it so I can fast-forward through the ads. It's not like I can miss the product placement during the show, anyway.
** The physics on Eureka is probably just as terrible as the biology, but I just don't care about that as much.
