More than a century ago, William Morton Wheeler proposed that social insect colonies can
be regarded as superorganisms when they have morphologically differentiated reproductive …

In this review I show that four major kinds of theoretical approaches have been used to
explain the scaling of metabolic rate in cells, organisms and groups of organisms in relation …

Many insects and arthropods live in colonies or aggregations of varying size. Group size
may affect collective organization either because the same individual behavior has different …

The concerted responses of eusocial insects to environmental stimuli are often referred to as
collective cognition at the level of the colony. To achieve collective cognition, a group can …

Approaches to macroevolution require integration of its two fundamental components, within
a hierarchical framework. Following a companion paper on the origin of variation, I here …

Their argument, described below, relies on a concept of assessing when an individual is a
fitness-bearing individual, and what it means to be a unit of selection. Wilson and Sober …

The allometric scaling of metabolic rate and what drives it are major questions in biology
with a long history. Since the metabolic rate at any level of biological organization is an …

The traditional focus of physiological and functional genomic research is on molecular
processes that play out within a single multicellular organism. In the colonial (eusocial) …

Dominance and Aggression in Humans and Other Animals: The Great Game of Life
examines human nature and the influence of evolution, genetics, chemistry, nurture, and the …

During their lifetime, superorganisms, like unitary organisms, undergo transformations that
change the machinery of their collective behaviour. Here, we suggest that these …
