A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.

Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.

Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

A 99-million year old beetle in amber was a myrmecophile—a social impostor of the earliest-known ant colonies—revealing the most ancient behavioral symbiosis yet discovered in the Metazoa.

Rats are highly social animals that show complex social skills, which has not been acknowledged enough when controlling them in the wild and conducting research in the laboratory.

When an individual makes a judgement about the actions of another individual, taking the latter's viewpoint into consideration enhances cooperation in society at large.

Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

Historical texts offer researchers in neuroscience, philosophy and literature the opportunity to work together to explore mysteries of the mind and human behavior.

A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.
