Perspectives and Conclusion Phylogenetic studies are probably going to be increasingly based on structural biological data and on statistical formalization. This reflects the importance of improved models, and of extracting the maximum information from sequence data.
Studies incorporating structural information are quite fruitful at the moment.
As well as the work described above, additional complexity is gradually being introduced. As such analyses become more specialized, however, there is some concern over whether there will ever be enough data to find these correlations reliably. Regarding statistical formalization, current research is successfully generalizing the statistical testing of phylogenetic hypotheses. They have stressed that both the use of the distribution and Monte Carlo simulations have become indispensable tools for biologists dealing with competing phylogenetic hypotheses. With our improving ability to handle phylogenetic questions statistically has come an increased interest in experimental design in phylogenetics.
