A biological taxonomy is a classification scheme based on character traits.
However Linnean taxonomy is a nested hierarchy through-n-through.
ID guy: Except that taxonomy is based on CHARACTERISTICS.
A taxonomy is a type of nested hierarchy based on a classification scheme, such as a biological classification.
Linnaean taxonomy is also a nested hierarchy, but he had very limited knowledge of Reptiles and he set Reptiles as a separate class of Animals; therefore the class is not monophyletic.
In other words, the nested hierarchy of the observed Linnaean taxonomy is explained as due to the nested hierarchy of the posited descent from common ancestors.
Darwin proposes that the nested hierarchy of Linnaean taxonomy is due to the nested hierarchy of descent.
A taxonomy is a nested hierarchy based on shared characterists.
A taxonomy is a type of nested hierarchy classification based on character traits.
BTW I said "clade" instead of "phylum" because the problem I see with Linnaean taxonomy is that it organizes the taxa on the basis of morphology BUT MAKES NO PREDICTIONS.
