At the same time, the retailer doubled its staff overseeing store assortments and decreased the stores that staff members dealt with.
In contrast, at low frequencies of cooperators rapid evolutionary dynamics lead to a decrease in assortment, which acts against the evolution of cooperation.
Only then could chromosomes form, because a newly formed chromosome can decrease the assortment load and give rise to a fully specialized system (compare Figure 2b and c).
This decreases positive assortment of cooperators and defectors, which acts against the evolution of cooperation.
At low frequencies of cooperators, rapid evolutionary dynamics decreased positive assortment (compare scenarios with and without selection in Figure 1).
These results emerged because greater migration rates lead to more mixing, which decreases positive assortment and makes it easier for defectors to exploit cooperators.
Both assortment models caused a significant decrease in model fit, but the SH model fitted the data relatively worse than the PA model (according to χ difference test, Akaike's information criterion (AIC), Bayesian information criterion (BIC), and Deviance information criterion (DIC)).
The chemicals are associated with an assortment of health concerns, including antisocial behavior, impaired fertility, decreased birth weight, diabetes, memory loss, undescended testicles, lowered levels of male hormones and hyperthyroidism.
When the genetic factors A and D were fixed to zero, the relative influence of ASM decreased from 11 to 0%, which implies that phenotypic assortment is based on a phenotype that completely reflects the genotype.
Basically, under social homogamy, resemblance between relatives is a function of shared environment (social resemblance), whereas, under phenotypic assortment, trait resemblance is a function of genetic resemblance between relatives, such that phenotypic correlations between individuals decrease with increasing genetic distance, as well as environmental resemblance.
