Here, I would like to propose that, in a roundabout kind of way, the MHC region could have evolved to promote the evolvability of the genes within it, by favouring frequent interallelic and intergenic gene conversion.
Summary: In this Hypothesis article, Johnson and Alberio propose that the determinative mechanisms for PGC specification in most model systems evolved to promote speciation and evolvability, not to maintain the germ line.
However, when everything clicks, a network of eager Internet evangelists evolves to promote and support the film.
However, from an evolutionary perspective, love can be viewed as a survival tool – a mechanism we have evolved to promote long-term relationships, mutual defence and parental support of children, and to promote feelings of safety and security Muneera Rashida is one half of Poetic Pilgrimage, a hip-hop and spoken word duo and one of the few Muslim female outfits around.

It's the first study that shows ulcer bugs adapt to different human populations, and "it's an example of how bacteria can evolve to promote chronic infection".
Thus, for active targeting, unlike the case of small molecular drugs where molecular structure has evolved to promote higher physiochemical affinity to specific sites, one aims to exploit these energy dependant endogenous processes.
And ultimately, Curtis says, it's about understanding how emotions in general may have evolved to promote certain advantageous behaviors.
The idea that character displacement, due to the foraging strategies of pollinators, promotes divergence in corolla-tube depth is related to two of the previously proposed hypotheses: that deep corollas evolve to promote flower constancy [20] and that they contribute to exclude unwanted visitors [13] [14].
It therefore seems as if this stable proliferative arrest evolved to promote development and survival of the organism.
