And much of what she did pointed the way for molecular studies by others.

Some molecular studies have shown that these are not related.

The latter suggestion has found more support in recent molecular studies.

This relationship was supported by a 2009 molecular study which placed the species in that family.

Molecular studies have put this divergence time at around 25 million years.

Further molecular studies may result in this hypothesis being modified.

All existing evidence for this hypothesis comes from molecular studies within the last decade.

Molecular studies, however, indicate that it is a distinct species.

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

Note that some changes to this taxonomy have been suggested by molecular studies.
