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 trait shared between species because they share an ancestral species.
Nursing theory is defined as "a creative and conscientious structuring of ideas that project a tentative, purposeful, and systematic view of phenomena". [1] Through systematic inquiry, whether in nursing research or practice, nurses are able to develop knowledge relevant to improving the care of patients.
Jean Watson, PhD, RN, AHN-BC, FAAN, LL (AAN) is an American nurse theorist and nursing professor who is best known for her theory of human caring. She is the author of numerous texts, including Nursing: The Philosophy and Science of Caring. Watson's research on caring has been incorporated into education and patient care at hundreds of nursing ...
Hennig coined the key terms synapomorphy, symplesiomorphy, and paraphyly. He also asserted, in his "auxiliary principle", that "the presence of apomorphous characters in different species 'is always reason for suspecting kinship [i.e., that species belong to a monophyletic group], and that their origin by convergence should not be presumed a ...
A celebrated conjecture of Vladimir Arnold relates the minimum number of fixed points for a Hamiltonian symplectomorphism :, in case is a compact symplectic manifold, to Morse theory (see [3]). More precisely, the conjecture states that φ {\displaystyle \varphi } has at least as many fixed points as the number of critical points that a smooth ...

Symplesiomorphy – an ancestral trait shared by two or more taxa. Plesiomorphy – a symplesiomorphy discussed in reference to a more derived state. Pseudoplesiomorphy – a trait that cannot be identified as either a plesiomorphy or an apomorphy that is a reversal. [15]
Imogene King (January 30, 1923 – December 24, 2007) was a pioneer of nursing theory development. Her interacting systems theory of nursing and her theory of goal attainment have been included in every major nursing theory text. These theories are taught to thousands of nursing students, form the basis of nursing education programs, and are ...
