Editing Convergent evolution (section)

====Tertiary structures====

Many proteins share analogous [[Protein structure|structural elements]] that arose independently across different genomes. There are several examples of convergent protein motifs sharing similar arrangements of structural elements.<ref>{{cite journal |last=Cheng |first=H. |last2=Kim |first2=B-H. |last3=Grishin |first3=N.
