It is not unusual for a phylogeny reconstruction to result in several equally robust phylogenetic trees that differ in their branching patterns. How can this be the case if evolution only took one true pathway?
What will be an ideal response?
Phylogeny reconstruction is in part a statistical procedure, and the reconstructions depend on the amount and nature of the input data and the assumptions inherent in the particular reconstruction method (maximum parsimony, maximum likelihood, etc.). Given these constraints, it is expected that phylogenetic analysis of a given data set will, at times, produce multiple, equally well-supported trees.
