The Lost World (Jurassic Park, #2)

life is so unbelievably complex,” Malcolm said. “Nobody realizes it. I mean, a single fertilized egg has a hundred thousand genes, which act in a coordinated way, switching on and off at specific times, to transform that single cell into a complete living creature. That one cell starts to divide, but the subsequent cells are different. They specialize. Some are nerve. Some are gut. Some are limb. Each set of cells begins to follow its own program, developing, interacting. Eventually there are two hundred and fifty different kinds of cells, all developing together, at exactly the right time. Just when the organism needs a circulatory system, the heart starts pumping. Just when hormones are needed, the adrenals start to make them. Week after week, this unimaginably complex development proceeds perfectly—perfectly. It’s incredible. No human activity comes close. “I mean, you ever build a house? A house is simple in comparison. But even so, workmen build the stairs wrong, they put the sink in backward, the tile man doesn’t show up when he’s supposed to. All kinds of things go wrong. And yet the fly that lands on the workman’s lunch is perfect.
