Evolutionary layering and the limits to cellular perfection.
Although observations from biochemistry and cell biology seemingly illustrate hundreds of examples of exquisite molecular adaptations, the fact that experimental manipulation can often result in improvements in cellular infrastructure raises the question as to what ultimately limits the level of molecular perfection achievable by natural selection. Here, it is argued that random genetic drift c...
متن کاملFundamental Limits to Cellular Sensing
In recent years experiments have demonstrated that living cells can measure low chemical concentrations with high precision, and much progress has been made in understanding what sets the fundamental limit to the precision of chemical sensing. Chemical concentration measurements start with the binding of ligand molecules to receptor proteins, which is an inherently noisy process, especially at ...

Evolutionary Limits and Constraints
Although evolution is a powerful process that leads to rapid changes in the characteristics of organisms, limits to evolution arise from a lack of genetic variation, a loss of well-adapted genotypes in populations due to gene flow, trait interactions leading to trade-offs, and/ or the difficulty of evolving simultaneous changes in a number of traits. Signatures of genetic constraints at the mol...
متن کاملMolecular and cellular limits to somatosensory specificity
Animals detect environmental changes through sensory neural mechanisms that enable them to differentiate the quality, intensity and temporal characteristics of stimuli. The 'doctrine of specific nervous energies' postulates that the different sensory modalities experienced by humans result of the activation of specific nervous pathways. Identification of functional classes of sensory receptors ...
