Michael Crichton Quote

After every major environmental change, a wave of extinctions has usually followed—but not right away. Extinctions only occur thousands, or millions of years later. Take the last glaciation in North America. The glaciers descended, the climate changed severely, but animals didn’t die. Only after the glaciers receded, when you’d think things would go back to normal, did lots of species become extinct. That’s when giraffes and tigers and mammoths vanished on this continent. And that’s the usual pattern. It’s almost as if species are weakened by the major change, but die off later. It’s a well-recognized phenomenon. It’s called Softening Up the Beachhead, Levine said. And what’s the explanation for it? Levine was silent. There is none, Malcolm said. It’s a paleontological mystery. But I believe that complexity theory has a lot to tell us about it. Because if the notion of life at the edge of chaos is true, then major change pushes animals closer to the edge. It destabilizes all sorts of behavior. And when the environment goes back to normal, it’s not really a return to normal. In evolutionary terms, it’s another big change, and it’s just too much to keep up with.

About Michael Crichton

John Michael Crichton (; October 23, 1942 – November 4, 2008) was an American author, screenwriter and filmmaker. His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films. His literary works heavily feature technology and are usually within the science fiction, techno-thriller, and medical fiction genres. Crichton's novels often explore human technological advancement and attempted dominance over nature, both with frequently catastrophic results; many of his works are cautionary tales, especially regarding themes of biotechnology. Several of his stories center on themes of genetic modification, hybridization, paleontology and/or zoology. Many feature medical or scientific underpinnings, reflective of his own medical training.
Crichton received an MD from Harvard Medical School in 1969 but did not practice medicine, choosing to focus on his writing instead. Initially writing under a pseudonym, he eventually published 25 novels in his lifetime, including: The Andromeda Strain (1969), The Terminal Man (1972), The Great Train Robbery (1975), Congo (1980), Sphere (1987), Jurassic Park (1990), Rising Sun (1992), Disclosure (1994), The Lost World (1995), Airframe (1996), Timeline (1999), Prey (2002), State of Fear (2004), and Next (2006). Four more novels, in various states of completion, were published after his death in 2008.
Crichton was also involved in the film and television industry. In 1973, he wrote and directed Westworld, the first film to use 2D computer-generated imagery. He also directed Coma (1978), The First Great Train Robbery (1978), Looker (1981), and Runaway (1984). He was the creator of the television series ER (1994–2009), and several of his novels were adapted into films, most notably the Jurassic Park franchise.
