Sentence examples for changes in traits from inspiring English sources
Our goal was to assess and quantify in the small rodent Phyllotis xanthopygus, changes in traits relevant to energy balance in response to its thermal landscape.
Common misconceptions include the ideas that individuals undergo changes in traits driven by need; evolution occurs at the level of individuals (versus populations); natural selection is random; and formation of new species is intentional.
The total length of the root system was sensitive to changes in traits regulating the number of lateral branches a given root order can produce (the inter-branch distance, the maximum length of root and its apical non-branching distance) and the elongation rate of main axes.
In this scenario, the incumbent, already toothed lineages would have been exapted and shown subsequent adaptive changes in traits of teeth (not their presence-absence) during cooling, hypothetically influencing speciation rates over time.
However, the rare likelihood that any particular change in a previously optimized and invariant phenotype could increase fitness or performance also depends on the traits 'intrinsic evolvability'; genetic and developmental modularity enabling changes to occur independent of pleiotropic effects (unselected changes in traits unrelated to the trait under selection and correlated fitness costs).
However, how evolutionary changes in traits may lead to reproductive isolation and the formation of new species is less understood.
Yet they remain recognisably evolutionary in style, primarily because they seek to explain the changes in trait frequencies in a population over time.
The timing of maturity (h2=0.12 0.56) and body weight (h2=0.20 0.27) exhibited significant heritabilities, allowing genetic changes in trait means in response to selection.
Examples of macroevolutionary patterns include: similar changes in trait evolution across multiple groups within a given lineage and pulses of evolution in response to climate change (Vrba [1995]; Congreve [2013]).
However, changes in trait values that occur on different lineages are.
The changes in trait architecture between the sexes allow a relaxation of the intersexual genetic correlation (rMF <1).
