After repeatedly confronting this question in various guises, we have recognized that it derives from a mistaken view of evolution shared by many people, including students.
In addition to parallel evolution, shared evolutionary history can also produce common morphological patterns across localities [ 8, 61].
Cold shock proteins (CSP) are amongst the most conserved proteins in evolution, sharing a cold shock domain (CSD) from pro- to eukaryotes [ 1].
Darwin's theory of evolution shared points of similarity with certain of the systems described in previous sections of this paper, but was unique in their combination.
The rationale was to test whether social evolution, shared aspects of life history such as using carcasses for developing larvae, or shared evolutionary history is associated with similar molecular evolution.
Recent analysis of genome-wide ohnolog distribution have revealed a common history of ancient, successive polyploidy events that are a common feature of genome evolution shared by all flowering plant linages [ 36].
This quite evident artifact of the analysis may be due to exceptionally high rates of evolution shared by these two sequences, a phenomenon possibly affecting also the clustering of Xenos and Armillifer with the five hemipteran sequences.
In sharp contrast to the charophycean lineages discussed above, the two representatives of the Charales display an extremely conservative pattern of mitochondrial genome evolution, sharing exactly the same gene content (fig. 2) and gene order (fig. 5) as well as a high proportion of group II introns (fig. 4).
Although cladograms are usually constructed based on shared and derived characteristics, they share with phylograms the fundamental basis of evolution and shared ancestry.
