As such, we have to recognize the real biochemical limitations that particular genes impose on the evolution of a quantitative trait, and recognize that there are regions of phenotypic space that may simply be inaccessible [50], [51].
Here, we investigate the effect that continuous variation in environmental temperatures imposes on the evolution of body size among species of the Liolaemus genus, using a comparative approach.
Last but not the least, combining the vertical and horizontal perspectives, we found that accessibility, affordability and accountability problems, and the social justice and sustainability of the ECE system, are all realistic challenges imposed on the inevitable evolution of ECE reform in China.
An enhanced auditory sensitivity to these frequencies raises the possibility that the acoustic and auditory specializations of aye-ayes have imposed constraints on the evolution of their vocal signals, especially their primary long-distance vocalization, the screech.
A set of practical constraints are imposed on the Differential Evolution algorithm to guide evolution toward the optimal surface that best represents the measured temperatures.
This specification imposes structure on the evolution of the relationship between leaving school in an economic downturn and access to employer-sponsored health insurance.
Hence, genetic correlations may impose constraints on the evolution of a given trait.
These observations indicate that the structure of molecular networks impose constraints on the evolution of their components.
Such interactions require a balance between expression levels of all genes in a group of interacting genes, which imposes constraints on the evolution of regulation of individual genes, resulting in lower opportunity for transcriptional compensation.
What is less clear, however, is how much phenotypic and genetic correlations with body mass impose constraints on the evolution of novel limb bone size and shape in mammals.
