N&C's (p. 162) argument that plesiomorphy is homology based on "occurrence of the same condition in the most recent common ancestor" is identical in its reasoning to the evolutionary taxonomists argument that paraphyly is monophyly.

Symplesiomorphy vs. Synapomorphy — What’s the Difference?

Homology has no implication on the direction of transformation, whereas symplesiomorphy as "primitive" condition and synapomorphy as "derived" condition refer directly to phylogenesis, the real historical evolutionary process of speciation and transformation.

Synapomorphy Vs Symplesiomorphy PDF Biological Classification

An ancestral character state (i.e., a plesiomorphy) shared by two or more lineages in a particular clade. For example, within the clade of terrestrial vertebrates (in which the ancestral character state is "has four legs"), both elephants and salamanders have four legs — and so having four legs is a symplesiomorphy for those two lineages.

[1] In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy ). [2] [3] [4] A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor.

[1] Imaginary cladogram. [2] The yellow mask is a plesiomorphy for each living masked species, because it is ancestral. [2] It is also a symplesiomorphy for them. But for the four living species as a whole, it is an apomorphy because it is not ancestral for all of them. The yellow tail is a plesiomorphy and symplesiomorphy for all living species.

PPT What is a synapomorphy? PowerPoint Presentation, free download

A derived or changed character state (i.e., an apomorphy) shared by two or more lineages in a particular clade. Synapomorphies are indicators of common ancestry. For example, within the clade of terrestrial vertebrates the ancestral, or plesiomorphic, character state is "has four legs." However, both owls and parrots have the synapomorphic character state "has two legs and

In cladistics terms the difference between symplesiomorphy and synapomorphy is that symplesiomorphy is an ancestral trait shared by two or more taxa while synapomorphy is a derived trait that is shared by two or more taxa of shared ancestry. symplesiomorphy English Noun ( symplesiomorphies )

Symplesiomorphy refers to a shared ancestral trait that is present in multiple groups of organisms. In other words, symplesiomorphies are traits that are inherited from a common ancestor and are shared among different groups of organisms.

What is the Difference Between Synapomorphy and Symplesiomorphy

The yellow tail is a plesiomorphy and symplesiomorphy for all living species. In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a.

PPT What is a synapomorphy? PowerPoint Presentation, free download

Synapomorphy vs. Symplesiomorphy Synapomorphy includes those characters that are shared and derived (those characters may or may not be present in the original or initial ancestors); whereas, symplesiomorphy includes the shared ancestral characters i.e., the characters derived from the initial ancestors.

In addition, synapomorphy and symplesiomorphy might also refer to a character state that refers to the absence of a structure/organ, which creates problems with traditional homology concepts. Hennig's terms synapomorphy and symplesiomorphy are necessary and sufficient for the evolutionary interpretation of character states.

A synapomorphy is a shared, derived character, common between an ancestor and its descendants. A character, or trait, is anything observable about the organism. It may be the size of the organism, the type of skin covering the organism has, or even things like eye color.
