Because of their close relationship to mammals, cynodonts continue to be the subject of much research, and this work has done much to elucidate the relationships of the earliest mammals, as well as the origins of many unique mammalian characters (e.g., see reviews in Hopson 1991, 1994 20011; Kielan-Jaworowska et al. 2003; Kemp 2005; Benton 2005; Prothero 2007).
Dinoflagellates comprise a well-supported monophyletic group based on both molecular data and many unique morphological characters [ 2].
The phylogenetic position of the Protura, traditionally considered the most basal hexapod group, is disputed because it has many unique morphological characters compared with other hexapods.
I won't go into great detail today about what I think makes a great bartender, but twenty or thirty years ago, good drinks were made, but the bartenders also had personalities, and many were unique characters.
Evolutionary trees, which depict patterns of descent from common ancestors among organisms, are very useful for understanding why this is the case and for reconstructing the evolutionary histories of many of the unique characters found in mammals.
Many of the unique characters have custom classes that replace the base squire class.
Many unique structural, physiological, biochemical, and behavioral characters make these fishes of particular interest to scientists.
Our analyses also supported the site of infection and site specificity as unique characters that follow the phylogenetic pattern of many myxozoan species as published elsewhere [ 21, 10, 22, 11].
Many early reviews gave Carnivàle good marks but also stated that its unique characters and story might prevent it from becoming a huge mainstream audience success.
