This has necessitated the evolution of neural control systems to coordinate swallowing and respiration.
The emergence of Earth's oxygen-rich atmosphere (known as the "oxygen catastrophe") due to photosynthetic organisms, as well as the presence of potentially damaging free radicals in the cell due to oxidative phosphorylation, necessitated the evolution of DNA repair mechanisms that act specifically to counter the types of damage induced by oxidative stress.
At the same time, the growth of individual cytoplasmic compartments would have necessitated the evolution of machinery to generate connections between adjacent blebs in order to integrate processes across these increasing large cells (for example, facilitating accurate cell division and cell polarization).
The structurally diverse pool of prostaglandin forms (PGA2, PGE2, PGF2α) and their analogues found in P. homomalla tissues [ 52, 66- 70] may have necessitated the evolution of a variety of prostaglandin-metabolizing CYPs, resulting in the diversity of closely related CYP4BL transcripts identified here.
The further evolution of molecularly imprinted polymer science and technology necessitates the development of robust predictive tools capable of handling the complexity of molecular imprinting systems.
This information theoretic approach [64], [66], [67], [137] [143] is grounded in the classical theory of entropy, but does not necessitate the temporal evolution of an ensemble.
Cryptic species are thought to be more common in groups where chemical senses are more highly developed than vision, such as most insects, because changes in chemical communication do not necessitate morphological changes for the evolution of reproductive barriers between sibling species [ 34].
In part this concern is addressed by the analysis depicted in Fig. 6, and this shows that a non Na+ pumping origin of the V/F/A-ATPases necessitates the assumption of convergent evolution or gene transfer, but it is not "at least 6" independent events, but only at least 2 independent events that survive closer scrutiny.
The availability of increasing numbers of sequenced genomes has necessitated a re-evaluation of the evolution of the WRKY transcription factor family.
The availability of increasing numbers of sequenced plant genomes has necessitated a re-evaluation of the evolution of the WRKY transcription factor family.
The increase trend of MRSA as noted in Tanzania; necessitate the coordinated surveillance to determine the evolution of these strains in Africa.
