Sentence examples for pattern of character from inspiring English sources

This and other recent discoveries are showing that the characteristic sauropod body plan evolved gradually, with a step-wise pattern of character appearance.

The evolution of the sacrum in basal sauropodomorphs, therefore, shows a complex pattern of character evolution, and the long recognized trend of increase in sacral count might have occurred convergently in several lineages of Sauropodomorpha since their earliest evolutionary history.

Carnivoramorpha and †Creodonta may be critical for determining the position of the wholly extinct clade †Mesonychia, which has played a pivotal role in our understanding of the pattern of character evolution in Cetacea (see discussion in [1]).

In the present contribution we describe this specimen, its geological provenance, analyze its phylogenetic relationships, and discuss the implications of its anatomy for understanding the evolutionary origin of Sauropoda, with particular emphasis on the pattern of character acquisition in the evolution of the sacrum and body size in Sauropodomorpha.

The phylogenetic models describe the pattern of character change as pure-phylogenetic, non-phylogenetic or punctuational.

However, because empirical phylogenetic tree estimates do not always reflect true evolutionary history [ 5, 6], inferring a "best estimate" tree does not eliminate the possibility that an alternative evolutionary history gave rise to the observed pattern of character data.

In particular, borrowing and convergence may produce similar patterns of character states but the mechanisms by which these patterns are produced are significantly different.

Cladistic approaches to evolutionary analysis seek to capture patterns of character states among a set of taxa that were created by descent with modification from ancestors through time (Freeman and Herron 2007).
