Selon les scientifiques, la vie sur Terre aurait Ă©tĂ© dominĂ©e par des espèces simples pendant les quelque 10 millions d’annĂ©es qui ont suivi ce cataclysme, les Ă©cosystèmes complexes n’étant apparus que plus tard. Cette thĂ©orie de longue date est cependant remise en question par une Ă©quipe de recherche internationale, dont font partie des scientifiques de l’UniversitĂ© 91şÚÁĎÍř et de l’UniversitĂ© du QuĂ©bec Ă  MontrĂ©al.</p></div></div></div><div class="field field-name-field-primary-image field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><img class="no-float" src="/channels/files/channels/styles/wysiwyg_medium/public/channels/image/fish_watsonulus3_gaopo_section_in_the_field_web.jpg?itok=jEP5sw48" width="160" height="120" alt="" /></div></div></div><div class="field field-name-field-published-date field-type-datestamp field-label-hidden"><div class="field-items"><div class="field-item even"><div class="custom-multi-date"><div class="multi-date first"><span class="label">PubliĂ©: </span><span class="day">27 </span><span class="month">February </span><span class="year">2023</span></div></div></div></div></div> Mon, 27 Feb 2023 16:15:06 +0000 webfull 187602 at /channels /channels/fr/news/au-seuil-d%E2%80%99une-extinction-massive-nous-pouvons-encore-nous-rattraper-268427 <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p></div></div></div><div class="field field-name-field-primary-image field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><img class="no-float" src="/channels/files/channels/styles/wysiwyg_medium/public/channels/image/gonzalez.jpg?itok=e6da6uB7" width="160" height="96" /></div></div></div><div class="field field-name-field-published-date field-type-datestamp field-label-hidden"><div class="field-items"><div class="field-item even"><div class="custom-multi-date"><div class="multi-date first"><span class="label">PubliĂ©: </span><span class="day">31 </span><span class="month">May </span><span class="year">2017</span></div></div></div></div></div> Wed, 31 May 2017 17:02:40 +0000 webfull 128620 at /channels
