Question

Quizplus · Accepted Answer

The principle of parsimony, often used in systematics for identifying the optimal phylogenetic tree, posits that the simplest explanation (in this case, the tree with the fewest evolutionary changes) is preferred. This approach minimizes the number of assumptions and changes needed to explain the observed data.
