The type of evidence that is least likely to result in changes to a phylogenetic tree is strong and well-supported evidence from multiple independent sources. When multiple lines of evidence consistently support a particular phylogenetic tree topology, it becomes more robust and less likely to change. For example, if different types of data, such as molecular sequences, morphological characteristics, and fossil records, all consistently support the same phylogenetic relationships, it provides a strong foundation for the tree's accuracy. In such cases, it becomes less likely that new evidence or analysis will drastically alter the overall tree topology. On the other hand, if the evidence is weak, conflicting, or based on a single source, there is a higher probability of changes to the phylogenetic tree as new data becomes available or alternative analytical methods are applied. In such cases, further research, increased sampling, or the incorporation of additional data can lead to revisions or refinements in the phylogenetic relationships.
