Of central interest to evolutionary biologists, is the understanding of the various fundamental pressures shaping the evolution of group living. Simply, what makes it a better option for animals to aggregate in social groups, and what are the costs in doing so? Here, I wish to focus on the potent effects social environments may have on individual physiology, with either deleterious or beneficial outcomes. Using colonial mammals (Columbian ground squirrels) and birds (king penguins) as case studies, and mixing bio-logging and life history approaches, I would like to present some of our studies on the effects of social environments, individual stress, energy allocation, and fitness. I will discuss whether I view those effects as pros or cons, and how they pertain to the evolution of group-living.
