The term parsimony implies that
A) the three-domain system is superior to the five-kingdom system of classification.
B) molecular data are more accurate in implying evolutionary relationships than homology.
C) the fewer assumptions that are made, the more probable the conclusion.
D) smaller clades are more accurate than larger clades.
E) shared derived traits shared by fewer organisms are more correct than those shared by more organisms.

Question

Quizplus · Accepted Answer

Parsimony in scientific and phylogenetic contexts refers to the principle that the simplest explanation or pathway, requiring the fewest evolutionary changes or assumptions, is preferred. This principle suggests that the hypothesis or tree that implies the least amount of change (i.e., the fewest assumptions) is more likely to be correct. It does not directly relate to the superiority of classification systems, the accuracy of molecular data over homology, the size of clades, or the correctness of traits based on how widely they are shared.
