WebDarwin’s suggestion directly anticipates phylogenetic bracketing, a method that uses shared characteristics of organisms in a clade to make predictions about the common ancestor of the clade and all of its descendants. WebPhylogenetic bracketing is a method of inference used in biological sciences. It is used to infer the likelihood of unknown traits in organisms based on their position in a …
Extant phylogenetic bracketing (EPB) This is a popular form of phylogenetic bracketing first introduced by Witmer in 1995. It works by comparing an extinct taxon to its nearest living relatives. For example, Tyrannosaurus, a theropod dinosaur, is bracketed by birds and crocodiles. See more Phylogenetic bracketing is a method of inference used in biological sciences.
