Plesiomorphic
Definition:
Example Sentences:
(1) Forty-six characters were coded in plesiomorphic and apomorphic states.
(2) Undecussated ipsilateral retinal projections, as present in the bowfin, are a widely distributed character in vertebrates and appear to be plesiomorphic for vertebrates.
(3) Clear synapomorphies with modern man combined with some plesiomorphic retentions indicate a slightly more primitive (and older?)
(4) This suggests that the circuitry in the intermediately complex pattern, as represented by Osteoglossum, is plesiomorphic (evolutionarily primitive) and the circuitry in both the simple pattern (seen in cyprinids) and the elaborate pattern (seen in percomorphs) is apomorphic (evolutionarily derived) for teleosts.
(5) The dorsomedial part of the lepidosirenid telencephalon corresponds to the septum in the most plesiomorphic living lungfish, Neoceratodus forsteri, but it differs considerably from the dorsomedial telencephalon (medial pallium) in amphibians.
(6) The posterior pretectal nucleus is relatively small in the bowfin, and the distribution of a small, versus a large, posterior pretectal nucleus in Teleostei and Halecomorphi suggests that this nucleus was small plesiomorphically.
(7) Direct-developing desmognathine salamanders have the plesiomorphic set of motor neurons, but appear to lack Mauthner neurons.

(9) This represents a true plesiomorphous character state in therian ontogeny.
(10) Species of Spirhapalum retained a relatively plesiomorphic distribution, and they are found in emydids (Europe) and batagurids (Asia).
(11) Comparison of the gene content of other fish, amphibians, and mammal syntenic groups suggests retention of plesiomorphic vertebrate gene arrangements in at least two poeciliid linkage groups.
