Thus, for the first time, TANGO enables the prediction of risky protein alterations that underlie this group of diseases.

..., for a total sample of 27 species. Using Bayesian statistical techniques, she was able to reconstruct a "robust" family tree of the Plethodontid salamanders. One feature that has been used to classify salamanders is their larval stage, much like the tadpole stage of frogs.
