" Let’s say we had a bad one, and all the plants and animals died, and the earth was clicking hot for a hundred thousand years. Life would survive somewhere—under the soil, or perhaps frozen in Arctic ice. And after all those years, when the planet was no longer inhospitable, life would again spread over the planet. The evolutionary process would begin again. It might take a few billion years for life to regain its present variety. And of course it would be very different from what it is now. But the earth would survive our folly. Life would survive our folly. Only we,” Malcolm said, “think it wouldn’t.” Hammond said, “Well, if the ozone layer gets thinner—” “There will be more ultraviolet radiation reaching the surface. So what?” “Well. It’ll cause skin cancer.” Malcolm shook his head. “Ultraviolet radiation is good for life. It’s powerful energy. It promotes mutation, change. Many forms of life will thrive with more UV radiation.” “And many others will die out,” Hammond said. Malcolm sighed. “You think this is the first time such a thing has happened? Don’t you know about oxygen?” “I know it’s necessary for life.” “It is now,” Malcolm said. “But oxygen is actually a metabolic poison. It’s a corrosive gas, like fluorine, which is used to etch glass. And when oxygen was first produced as a waste product by certain plant cells—say, around three billion years ago—it created a crisis for all other life on our planet. Those plant cells were polluting the environment with a deadly poison. They were exhaling a lethal gas, and building up its concentration. A planet like Venus has less than one percent oxygen. On earth, the concentration of oxygen was going up rapidly—five, ten, eventually twenty-one percent! Earth had an atmosphere of pure poison! Incompatible with life! "

" There were several monitors, all running so fast it was hard to see what they were showing. Wu pushed a button and slowed one image. “Here you see the actual structure of a small fragment of dinosaur DNA,” Wu said. “Notice the sequence is made up of four basic compounds—adenine, thymine, guanine, and cytosine. This amount of DNA probably contains instructions to make a single protein—say, a hormone or an enzyme. The full DNA molecule contains three billion of these bases. If we looked at a screen like this once a second, for eight hours a day, it’d still take more than two years to look at the entire DNA strand. It’s that big. "

" Fractals are a kind of geometry, associated with a man named Mandelbrot. Unlike ordinary Euclidean geometry that everybody learns in school—squares and cubes and spheres—fractal geometry appears to describe real objects in the natural world. Mountains and clouds are fractal shapes. So fractals are probably related to reality. Somehow. “Well, Mandelbrot found a remarkable thing with his geometric tools. He found that things looked almost identical at different scales.” “At different scales?” Grant said. “For example,” Malcolm said, “a big mountain, seen from far away, has a certain rugged mountain shape. If you get closer, and examine a small peak of the big mountain, it will have the same mountain shape. In fact, you can go all the way down the scale to a tiny speck of rock, seen under a microscope—it will have the same basic fractal shape as the big mountain. "

" Can you tell me anything?” “It’s a bioengineering firm.” “Bioengineering,” Barney said. “Well, there’s the obvious …” “Which is?” “A DNA molecule.” “Oh, come on,” Nedry said. “Nobody could be analyzing a DNA molecule.” He knew biologists were talking about the Human Genome Project, to analyze a complete human DNA strand. But that would take ten years of coordinated effort, involving laboratories around the world. It was an enormous undertaking, as big as the Manhattan Project, which made the atomic bomb. “This is a private company,” Nedry said. "

" Reptiles are abhorrent because of their cold body, pale color, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom; wherefore their Creator has not exerted his powers to make many of them. "
