Finally, "composite" domains do not represent evolutionary units and are purely geometric, but may be useful in studies of convergent evolution.
Our results confirmed that current taxonomy does not represent evolutionary units in the Rhinella crucifer group.
In other words, these AlkB domains were as similar to each other as the other three domains with respect to sequence identity, but they did not represent a consistent evolutionary history when compared to the other domains of this polyprotein.
Thus the greater availability of toxicity data has contributed to the evolution of QSAR models; however, because of the time consuming nature of generating extra experimental data, this factor did not represented the main evolutionary driving force.
There is a very limited number of indels occurring on internal nodes, although these internal nodes do not represent short evolutionary times.
Although the different genders clearly do not represent independent evolutionary lineages, this allowed examination of how the contrasts between uninfected snail genders compared to the contrasts between species.
At the genome level, the C-value enigma indicates that the size of genome does not represent the evolutionary order of different species [ 55, 56].
However, the individual Q matrix of assignment to groups shows that P. beccariana, P. forbesiana, and P. lowreyana do not represent distinct evolutionary lineages according to the GSC because they do not group as unique clusters; with other individuals in the Q matrix having > 0.8 PP of falling within those groups.
These phenotypes are probably ephemeral entities with low fitness that contribute to local adaptation and do not represent potentially independent evolutionary lineages but are rapidly eliminated.
Thus, it appears that the changes of expression pattern found in small-scale studies do not represent very rare evolutionary events, but rather that divergence by expression is a relatively common phenomenon between human and mouse orthologs.
