Circular RNA repertoires are associated with evolutionarily young transposable elements
F. Gruhl, P. Janich, H. Kaessmann, D. Gatfield
The paper analyzes circRNA repertoires across five species and finds that most circRNAs arise from non-conserved exonic loci and are linked to young, species-specific transposable elements, suggesting convergent evolution rather than functional conservation.
