delboy Posted August 26, 2015 Share Posted August 26, 2015 Sounds like an exam question. Lobefin, reptile then (probably) frog, salamander. Source - Vertebrate Palaeontology, Benton. Link to comment Share on other sites More sharing options...

Arete Posted August 27, 2015 Share Posted August 27, 2015 Thnx...but how come reptiles have appeared earlier than frogs n salamanders They didn't. Amphibians are an older lineage than reptilia. 1 Link to comment Share on other sites More sharing options...
delboy Posted August 27, 2015 Share Posted August 27, 2015 Thnx...but how come reptiles have appeared earlier than frogs n salamanders Because frogs and salamanders are 'advanced' amphibians. The first amphibians appeared before reptiles but frogs and salamanders didn't evolve until some time later. Link to comment Share on other sites More sharing options...
