ody knows whether it's a dangerous development or not。 So these behavioral processes can happen faster than we usually think evolution occurs。 In ten thousand years human beings have gone from hunting to farming to cities to cyberspace。 Behavior is screaming forward； and it might be nonadaptive。 Nobody knows。 Although personally； I think cyberspace means the end of our species。〃
〃Yes？ Why is that？〃
〃Because it means the end of innovation；〃 Malcolm said。 〃This idea that the whole world is wired together is mass death。 Every biologist knows that small groups in isolation evolve fastest。 You put a thousand birds on an ocean island and they'll evolve very fast。 You put ten thousand on a big continent； and their evolution slows down。 Now； for our own species； evolution occurs mostly through our behavior。 We innovavate new behavior to adapt。 And everybody on earth knows that innovation only occurs in small groups。 Put three people on a mittee and they may get something done。 Ten people； and it gets harder。 Thirty people； and nothing happens。 Thirty million； it bees impossible。 That's the effect of mass media … it keeps anything from happening。 Mass media swamps diversity。 It makes every place the same。 Bangkok or Tokyo or London： there's a McDonald's on one corner； a Benneton on another； a Gap across the street。 Regional differences vanish。 All differences vanish。 In a mass…media world； there's less of everything except the top ten books； records； movies； ideas。 People worry about losing species diversity in the rain forest。 But what about intellectual diversity … our most necessary resource？ That's disappearing faster than trees。 But we haven't figured that out； so now we're planning to put five billion people together in cyberspace。 And it'll freeze the entire species。 Everything will stop dead in its tracks。 Everyone will think the same thing at the same time。 Global uniformity。 Oh； that hurts。 Are you done？〃
〃Almost；〃 Harding said。 〃Hang on。〃
〃And believe me； it'll be fast。 If you map plex systems on a fitness landscape； you find the behavior can move so fast that fitness can drop precipitously。 It doesn't require asteroids or diseases or anything else。 It's just behavior that suddenly emerges； and turns out to be fatal to the creatures that do it。 My idea was that dinosaurs … being plex creatures … might have undergone some of these behavioral changes。 And that led to their extinction。〃
〃What； all of them？〃
〃It just takes a few；〃 Malcolm said。 〃Some dinosaur roots in the swamps around the inland sea； changes the water circulation； and destroys the plant ecology that twenty other species depend on。 Bang！ They're gone。 That causes still more dislocations。 A predator dies off； and its prey grow unchecked。 The ecosystem bees unbalanced。 More things go wrong。 More species die。 And suddenly it's over。 It could have happened that way。〃
〃Just behavior。。。〃
〃Yes；〃 Malcolm said。 〃Anyway； that was the idea。 And I had this nice thought that we might prove it。。。。But now it's finished。 We have to get out of here。 You better tell the others。〃
Thorne clicked on the radio。 〃Eddie？ It's Doc。〃
There was no answer。
〃Eddie？〃
The radio crackled。 And then they heard a noise that at first sounded like static。 It was a moment before they realized it was a high…pitched human scream。
The High Hide
The first of the raptors hissed as it began jumping up； clattering against the high hide shaking the structure。 Its claws raked against the metal； and it fell down again。 Eddie was astonished at how high it jumped … the animal could leap eight feet straight up； again and again； without apparent effort。 Its jumps attracted the other animals； which slowly came back to circle the hide。
Soon the hide was surrounded by leaping； snarling raptors。 It swayed back and forth as the animals slammed into it； clawed for purchase； and fell back again。 But more ominously； Levine saw； they were learning。 Already； some of them had begun to use their clawed forearms to grip the structure； holding on while their legs got footing。 One of the raptors came within a few feet of their little shelter before finally falling back。 The falls never seemed to hurt the animals。 They immediately leapt up； and jumped again。
Eddie and the kids scrambled to their feet。 Levine said； 〃Get back！ Don't look out；〃 and he pushed the kids into the center of the shelter。
Eddie was bent over his knapsack； and held up an incandescent flare。 He poppcd it and flung it over the side； two of the raptors fell away。 The flare sputtered an the wet ground； casting harsh red shadows。 But the raptors kept ing。 Eddie pulled up one of the aluminum bars from the floor； leaned over the side railing brandishing the bar like a club。
One of the raptors had already climbed high enough to dart forward； jaws gaping； at Eddie's neck。 Surprised； Eddie shouted and jerked his head back； the raptor narrowly missed him； but its jaws closed on his shirt。 Then the raptor fell back； jaws clenched tight； and its weight pulled Eddie forward over the failing。
He yelled 〃Help me！ Help！〃 as he started to topple over the side； Levine threw his arms around him； dragging him back。 Levine looked past Eddie's shoulder at the raptor； which was now dangling in space； hissing furiously； still gripping the shirt。 Eddie pounded the raptor on the snout with his bar。 But the raptor held on like a bulldog。 Eddie was bent precariously over the railing； he might fall at any moment。
He jabbed the bar into the animal's eye； and abruptly the raptor released its grip。 The two men fell back into the shelter。 When they got to their feet； they saw raptors climbing up the sides of the hide。 As they appeared at the rail； Eddie swung at them with the strut； knocking them back。
〃Quick！〃 he shouted to the kids。 〃Up on the roof！ Quick！〃 Kelly started climbing one of the struts； then pushed herself easily up onto the roof。 Arby stood there； his expression blank。 She looked back down and said； 〃e on； Arb！〃
The boy was frozen； his eyes wide with fear。 Levine ran to help him； lifted him up。 Eddie was swinging the strut in wide arcs； the metal smacking against the raptors。
One of the raptors caught the strut in its jaws and jerked it hard。 Eddie lost his balance； twisted； and fell backward； toppling over the side。 He cried 〃Nooo！〃 as he fell。 Immediately all the animals dropped down to the ground。 They heard Eddie screaming in the night。 The raptors snarled。
Levine was terrified。 He was still holding Arby in his arms； Pushing him up to the roof 〃Go on；〃 he kept saying。 〃Go on。 Go on。〃
From the roof； Kelly was saying； 〃You can do it； Arb。〃
The boy gripped the roof； pulling himself up； his legs churning in panic。 He kicked Levine hard in the mouth and Levine dropped him。 He saw the boy slide away； and drop backward to the ground。
〃Oh Christ；〃 Levine said。 〃Oh Christ。〃
Thorne was underneath the trailer； unhooking the cable。 He released it； crawled out； and sprinted for the Jeep。 He heard the whirr of a motor and saw that Sarah had gotten onto the motorbike； and was already racing off； a Lindstradt rifle slung across her shoulder。
He got behind the wheel； turned on the engine； and waited impatiently while the cable winched in； the hook sliding across the grass。 It seemed to take forever。 Now the cable was snaking around the tree。 He waited。 He looked over and saw the light from Sarah's bike moving off through the foliage； heading down toward the high hide。
At last the winch motor stopped。 Thorne threw the car in gear； and roared away from the clearing。 The radio clicked。 〃Ian；〃 he said。
〃 Don't worry about me；〃 Malcolm said； in a dreamy voice。 〃I'm just fine。〃
Kelly was lying flat on the angled roof of the shed； looking down over the side。 She saw Arby hit the ground； on the other side of the structure from Eddie。 He seemed to hit hard。 But she didn't know what happened to him； because she had turned away to grip the wet roof； and when she looked back down again； Arby was gone。
Gone。
Sarah Harding drove fast on the muddy jungle road。 She wasn't sure where she was； but she thought by following the terrain downward she would eve
