Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects-instead of vertebrates-might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence. Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are extinct. This gap is why the idea of "fish with feet" seems so peculiar to us, yet such animals were once a vital part of our world, and if the Devonian extinctions had not happened, members of these species, like the famous Acanthostega and Ichthyostega, might have continued to live in our rivers and lakes. Synthesizing decades of research and including a wealth of new discoveries, this accessible, comprehensive text explores the causes of the Devonian extinctions, the reasons vertebrates were so severely affected, and the potential evolution of the modern world if the extinctions had never taken place. 410 0$aCritical moments and perspectives in earth history and paleobiology. 606 $aExtinction (Biology) 606 $aPaleontology$yDevonian 608 $aElectronic books. 615 0$aExtinction (Biology) 615 0$aPaleontology 676 $a560.174 700 $aMcGhee$b George R$01026403 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910464891703321 996 $aWhen the invasion of land failed$92464289 997 $aUNINA LEADER 01498nam 2200373Ka 450 001 9910694695703321 005 20051019101217.0 035 $a(CKB)5470000002363738 035 $a(OCoLC)62110818 035 $a(EXLCZ)995470000002363738 100 $a20051019d2005 ua 0 101 0 $aeng 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aStatistical data for the Boeing-747-400 aircraft in commercial operations$b[electronic resource] $efinal report 210 1$aWashington, D.C. :$cU.S. Dept. of Transportation, Federal Aviation Administration, Office of Aviation Research,$d[2005] 215 $a1 volume $cdigital, PDF file 300 $aTitle from title screen (viewed on Oct. 19, 2005). 300 $a"January 2005." 517 $aStatistical data for the Boeing-747-400 aircraft in commercial operations 606 $aBoeing 747 (Jet transports) 606 $aLoad factor design$xData processing 606 $aAirplanes$xDesign and construction$xData processing 615 0$aBoeing 747 (Jet transports) 615 0$aLoad factor design$xData processing. 615 0$aAirplanes$xDesign and construction$xData processing. 712 02$aUnited States.$bFederal Aviation Administration.$bOffice of Aviation Research. 801 0$bGPO 801 1$bGPO 906 $aBOOK 912 $a9910694695703321 996 $aStatistical data for the Boeing-747-400 aircraft in commercial operations$93428714 997 $aUNINA LEADER 01006nam# 22002531i 450 001 UON00380624 005 20231205104526.151 010 $a97-517-3277-8 100 $a20100426d2007 |0itac50 ba 101 $atur 102 $aTR 105 $a||||b ||||| 200 0 $a1 210 $aIstanbul$cKultur ve Turizm Bakanl?g?$d2007 215 $a440 p.$cill.$d29 cm. 461 1$1001UON00380623$12001 $aTurkiye' de Muzecilik$e100 muze 1000 eser$feditor Ara Altun$1210 $aIstanbul$cKultur ve Turizm Bakanligi$d2007$1215 $a2 v.
