The evolutionary relationship of the family is still unclear.

But it has the genes to do so, highlighting the close evolutionary relationship between the two species.

The evolutionary relationships of this species have always been controversial.

This technique may also be used to determine evolutionary relationships among organisms.

A superfamily groups together domains which have an evolutionary relationship.

Future molecular studies should provide further insights into their evolutionary relationships.

The taxonomic and evolutionary relationship of these two groups is poorly understood.

All proteins should be classified to structural families to understand their evolutionary relationships.

The four major groups, although convenient, do not appear to be based on real evolutionary relationships.

In biology, the technique is used to determine the evolutionary relationships between different species.
