  • Tree evaluation and statistical testing procedures.

Main Results:

  • Established protocols for sequence data alignment.
  • Demonstrated phylogenetic tree construction from aligned sequences.
  • Discussion on the strengths and limitations of different phylogenetic assumptions.

Conclusions:

  • The presented procedures offer a framework for reliable phylogenetic analysis.
  • Understanding underlying assumptions is key to valid tree inference.
  • This work aids researchers in selecting appropriate methods for their evolutionary studies.
