Luminous 3-D Jungle Is a Biologist’s Dream


When watching a Hollywood movie that has robed itself in the themes and paraphernalia of science, a scientist expects to feel anything from annoyance to infuriation at facts misconstrued or processes misrepresented. What a scientist does not expect is to enter into a state of ecstatic wonderment, to have the urge to leap up and shout: “Yes! That’s exactly what it’s like!”

So it is time for all the biologists who have not yet done so to shut their laptops and run from their laboratories directly to the movie theaters, put on 3-D glasses and watch the film “Avatar.” In fact, anyone who loves a biologist or may want to be one, or better yet, anyone who hates a biologist — and certainly everyone who has ever sneered at a tree-hugger — should do the same. Because the director James Cameron’s otherworldly tale of romance and battle, aliens and armadas, has somehow managed to do what no other film has done. It has recreated what is the heart of biology: the naked, heart-stopping wonder of really seeing the living world.

The real beauty of it, though, is that you do not have to be a scientist to enjoy the experience. “Avatar” is well within reach of becoming the highest-grossing film of all time. And while the movie’s dazzling animation and use of 3-D has received so much attention, it cannot be anything but the intense wonder so powerfully elicited, rather than merely the technical wizardry itself, that has people lining up to see it.

There have, of course, been many films that have depicted the excitement of scientists during discovery (think of Laura Dern in “Jurassic Park,” gleefully sticking her hand into a pile of dinosaur dung), and, from “Lord of the Rings” to “Star Trek,” there has been no shortage of on-screen fantastical floras and faunas.

But rather than having us giggling at a tribble or worrying over the safety of the children when a T. rex attacks, Mr. Cameron somehow has the audience seeing organisms in the tropical-forest-gone-mad of the planet Pandora just the way a biologist sees them. With each glance, we are reminded of organisms we already know, while marveling over the new and trying quickly to put this novelty into some kind of sensible place in the mind. It is a mental tickle, and wonderful confusion sparks the thought, “Oh, that looks like a horse, but wait, it has six legs and it’s blue, and whoa, that looks like a jellyfish but it’s floating in the air and glowing.”

The clues that we are “not in Kansas anymore,” as we are told early on, can be seen in every aspect of the life of Pandora. If there is one color that is most decidedly not a classic Earth tone, one that is least associated with living things, it might just be neon blue. And so many things on Pandora, like the Pterodactyl-like ikran and the deerlike yerik, are a staring, screaming blue. Another thing we do not expect from most living things is light. Yet on Pandora, life glows everywhere in the night, including the long, pulsating white Spanish-moss-like strands elegantly dangling off tree branches and the brightly glowing green and purple ferns.

And touching closest to home, Mr. Cameron has put a version of ourselves on Pandora, the Na’vi people, with whom he uses every trick. For they are blue, they have bioluminescing spots on their faces and they display the other of Pandora organisms’ stunning quirks: they are huge, at 10 feet tall.

To so strongly experience these kinds of wonderfully shocking similarities and dissimilarities among living things is the kind of experience that has largely been the prerogative of biologists — especially those known as taxonomists, who spend their days ordering and naming the living things on Earth. But now, thanks to Mr. Cameron, the entire world is not only experiencing this but also reveling in it.
