How would you arrange the following in the ascending order of evolution...

Reptiles, lobefins, frog, salamander?

Sounds like an exam question.

Because frogs and salamanders are 'advanced' amphibians. The first amphibians appeared before reptiles but frogs and salamanders didn't evolve until some time later.
