And if, as one leading theory holds, this is all explained by our deeply rooted evolutionary preference for "affiliat[ing] with other forms of life", then it ought to follow that even non-green natural settings bring some benefits.
In contrast, Casuarina strains have discarded rather than acquired genes to limit hosts and inhabited environments, suggestive of an evolutionary preference for specialist symbiosis.
The high conservation of the C terminal Q-rich domain of GAF in insects, suggests that there is a strong evolutionary preference to maintain such associated structure and function.
Therefore, these results argue against any evolutionary preference for fusions involving more obligately associated subunits at the intracomplex level, instead suggesting that selection for assembly conservation plays a more important role.
Thus we see that subunits that undergo fusion are rarely observed in isolation, whereas this is quite common for protein complexes in general, suggesting an evolutionary preference for gene fusion events in obligate complexes.
To ask whether there was an evolutionary preference for reciprocal mutations that supported the formation of an intra- or interloop configuration we examined deviations from the canonical stem sequences across the bona fide monomers of the 27 mammals.
Though not adequately understood, these evolutionary host preferences may benefit the mosquitoes in a number of ways including the identification of hosts with more nutritive blood, or those who are less defensive against mosquito bites [3], [4].
Hence the evolutionary stability of preferences provides at most an incomplete account of preference change.
The framework of set-based evolutionary optimization integrating preferences is illustrated in "PSEA-m".
In addition, we found that there are different evolutionary rates and preferences for molecular function or biological process for no AS gene families and AS gene families.
