Long after the collapse of the Soviet Union, nonalignment persisted in India, evolving into a pragmatic approach to troublesome neighbors like Iran, analysts say.
1 Hepatotropic viruses adapted to persist in the liver have evolved to take advantage of this environment and trigger dysfunctional adaptive immune responses during acute (adenovirus) and chronic (hepatitis B virus [HBV] and hepatitis C virus [HCV]) virus infections of the liver.
The reason Militinae were able to evolve and persist in this carnivorous niche is therefore precisely because they have this pre-adaptation of living and co-operating with ants, she added.
We show that in order to persist in time, these systems must evolve in such a way that an easy access to nutrients is ensured: their shapes develop in such a way as to minimize the time to reach the nutrient source.
Functional characterization of microbial ligands that are differentially expressed in the complex enzootic cycle of B. burgdorferi is critical to understanding the adaptive strategies of a pathogen that has evolved to persist in diverse tissue environments resulting in multi-system disorders.
Conservation biologists have largely focussed on the latter, even though adaptive genetic diversity is needed for organisms to evolve and persist in changing environments.
These issues impact individuals during the acute phase of diagnosis and treatment, but can evolve or persist in the long-term phase of survivorship 5, 6.
This form of balancing selection in which female mate choice and intrasexual competition, combined with predator preferences for red and yellow males, interact may ultimately provide opportunities for AMSs to evolve and persist in the population.
Why does a president who declined to defend the Defense of Marriage Act persist in the ridiculous pretense of an "evolving" position, one might reasonably ask (an evolution that will be complete, one assumes, the day he wins re-election), when same-sex marriage might actually be a political winner, and his wink-and-a-nod approach to the issue looks so transparently calculated?
Constructal law states that "for a finite-size system to persist in time (to live), it must evolve in such a way that it provides greater and greater access to the currents flowing through it".
