Pattern and parsimony
The most likely reason for this pattern is based on the principle of parsimony — which says that the simplest scientific explanation that fits the evidence is the best one. In this case, the simplest explanation for the pattern is that hummingbird pollination evolved once in the ancestor of the hummingbird-oriented clade (marked with a red ...

None of the above. Which of the following statements is true about the principle of parsimony? a. It is a way to avoid identifying the outgroup of a clade. b. A way for scientists to distinguish between alternate hypotheses. c. This principle cannot be applied to molecular data. d. A study that uses a longitudinal, multiple-regression approach or a study that uses the pattern and parsimony approach have what in common? A - They assess cross-lag correlations. B - They are unable to ever establish causation. C - They involve more than two measured variables. D - They study changes over a period of time There has been a tension among parsimony advocates between pattern and process, going back to the battles between numerical taxonomists and evolutionary systematists we talked about last time. Pattern cladists or transformed cladists are one extreme end of the spectrum.Parsimony can provide a similar benefit in various everyday situations. For example, preferring simpler explanations can help us avoid jumping to conclusions, in cases where we are prone to see patterns in noise or connections between unrelated things (a phenomenon called apophenia). In addition, parsimony can help us avoid unnecessarily ... Similarly to maximum parsimony, maximum likelihood reconstructs ancestors at all nodes of each considered tree, but it also assigns branch lengths based on the probabilities of mutations. For each possible tree topology, the assumed substitution rates are varied to find the parameters that give the highest likelihood of producing the observed ...

Pattern cladists or transformed cladists are one extreme end of the spectrum. They put forward the idea that cladistic (in this case = strict parsimony) methods do not need, and in fact are better off without an evolutionary (process) justification.Abstract. According to the principle of parsimony, model selection methods should value both descriptive accuracy and simplicity. Here we focus primarily on Bayes factors and minimum description length, explaining how these procedures strike a balance between goodness-of-fit and parsimony. parsimony A principle stating that the simplest explanation accounting for the observations is the preferred explanation. When reconstructing the evolutionary relationships among lineages, the principle of parsimony implies that we should prefer the phylogeny that requires the fewest evolutionary changes.
