However, in general, PTA estimates for calving traits benefitted from multi-trait models.
In the other examples (Fig. 2B E), positive group selection on a trait occurs, indicating that the higher group averages for the trait benefits others in the group, increasing their fitness (Heisler and Damuth 1987), regardless of the effect of individual selection.
"Mollie believes fervently that the lessons learned through athletics — about competition, teamwork and integrity — translate into skills and traits that benefit our graduates long after they complete their varsity careers.
Frequent interspecific interaction can lead to negative feedback (eg, competition and predation) and reciprocal cooperation (mutualism), with fitness reflecting the trade-off between balancing individual sacrifice, if any, and traits that benefit the group, for example, stabilization of population, food web, or ecosystem structure.
To assess the effectiveness of the Healthy School and Drugs (HSD) program for secondary schools on the development of substance use among Dutch early adolescents and to explore whether boys, adolescents of lower educational backgrounds, or adolescents high on personality risk traits, would benefit more from the HSD program than others.
Why? Morality seems to defy the image of natural selection as "selfish," favoring only traits that benefit the individual in a competitive "struggle for existence".
The mere existence however, of traits that benefit the group is not enough to show that they are adaptations; in order to be an adaptation, under Williams' view, the trait must be an engineering adaptation that evolved by natural selection.
According to eudaimonism, the good life is the eudaimon life, and the virtues are what enable a human being to be eudaimon because the virtues just are those character traits that benefit their possessor in that way, barring bad luck.
Efforts to identify effective materials, coupled with the optimum combination of desirable thermodynamic, kinetic, and stability traits, would benefit as well from the application of computational materials science tools that are capable of comparing thousands of materials couples in short order.
