What Relative Neocortex Size Tells Us About Social Evolution

The paper examines how changes in primate brain structure, specifically subcortical and neocortex volumes, relate to social evolution through pair-living and group-living lifestyles.

Casual Versus Fractal Modularity in Mammalian Social Organisation

The paper analyzes multilevel social systems in mammals and birds, distinguishing between fractally modular and casually modular structures, and links them to neocortex size and cognitive demands.

Maternal time budgets of feral goats at high latitudes in northwest Europe.

This study shows lactating feral goats at high latitudes increase foraging time but not enough to meet their kids' nutritional needs, and they minimize thermal costs by spending more time in shelter and at lower altitudes.

Insectivorans and Carnivorans Exhibit the Same Social Brain Relationship as Primates

The paper shows that the social brain relationship observed in primates also applies to Insectivorans and Carnivorans, suggesting shared principles in mammalian social evolution.

Impact of Climate, Habitat and Scale on the Population Dynamics of Feral Goats on the Isle of Rum, NW Scotland

The paper analyzes how climate, habitat, and scale affect feral goat population dynamics on the Isle of Rum, finding that winter temperatures and the NAO index influence growth rates, while red deer limit foraging access.

Processing of Different Social Scales in the Human Brain

The paper investigates how the brain processes different social scales of emotional closeness and finds distinct neural patterns for close versus distant relationships.

Network Structure and Social Complexity in Primates

The paper analyzes primate grooming networks to show three social grades arise from time constraints on social bonding, with some genera developing multilevel sociality similar to human networks.

The human brain views selfish behaviour towards genetic vs. non-genetic sibling differently

This study shows that knowledge of genetic relationships modulates brain activity during moral dilemmas involving siblings.
