We argue that this original tree topology is an artefact arising from the fact that Acanthopterygian MyoD2 has evolved asymmetrically relative to MyoD proteins in other vertebrate lineages (note the long branch lengths leading to Acanthopterygian MyoD2 sequences in Fig. 1a d).
A robust regulatory physiologic system has evolved to maintain relative constancy of weight, an equilibrium broken by modern lifestyles leading to the development of obesity, type 2 diabetes and other metabolic disorders.
We used the results to determine whether there is variation in ploidy and/or genome size in A. kamchatica and its parents, and to determine how genome size has evolved in polyploids relative to their diploid parents.
By measuring the substitution rates AB, AC, and BC, it is possible to infer the rates OA and OB and to perform a χ 2 -test to determine whether these rates are comparable (the null hypothesis) or whether one lineage has evolved at a relative accelerated or decelerated rate, thus violating the behavior of a molecular clock.
Non-cell autonomous phenomena, mostly embodied by cell-cell communication, is underexplored and perhaps has evolved to control the relative proportions of cell types.
As we would expect for a signaling behavior that has evolved to maximize signal strength relative to the background environment [16], the data in this study suggest that eagle owls preferentially leave white faeces on the darkest and most detectable surfaces, and preferentially leave prey species with conspicuous plumage at highly visible plucking sites.
The use of corticosteroids in the management of sepsis has evolved with the identification of relative adrenal insufficiency, which occurs in 50 75% of patients with septic shock [ 13].
An analysis of peptide evolutionary rates between Cxqdsx and the dsx gene of the closely related Cx. pipiens form pipiens (Cxpipdsx, also generated in this study) shows that the male-specific component of the transcript has evolved at accelerated evolutionary rates relative to the female isoform, and contains sites exhibiting signs of positive selection.
As befits a place that can take pride in its otherness and even in its relative isolation, Staten Island has evolved, if not exactly its own language, then certainly a lexicon of words and phrases that require explanation to off-islanders.
Thus, in vertebrates, p120 has evolved one or more essential functions relative to its invertebrate counterpart, and a critical role with respect to the classical cadherins.
