Organizing and summarizing search results for youMaximum parsimony is a principle in phylogenetics that suggests the simplest explanation, or the one requiring the fewest evolutionary changes, is preferred when constructing a phylogenetic tree. This method aims to minimize the total number of character changes or evolutionary steps required to explain the observed data, making it a widely used approach in estimating evolutionary relationships among species or genes.4 Sources

Maximum parsimony (phylogenetics) - Wikipedia
In phylogenetics and computational phylogenetics, maximum parsimony is an optimality criterion under which the phylogenetic tree that minimizes the total number of character-state changes (or minimizes the cost of differentially weighted character-state changes). Under the maximum-parsimony … See more

What Is the Principle of Parsimony in Biology? - Seattle PI
- Humans werent around when most species diverged, so biologists trying to recreate phylogenetic trees must work from genetics, models and fossil records to determine relationships. In phylogeny, the principle of maximum parsimony is one method used to infer relationships between species. It states that the tree with the fewest common ancestors is th...
