Eusocial animals express complex behaviors, like group decision-making. Evolutionary biologists have asked how and why eusociality has evolved, and what we can learn from eusocial organisms. Aa Aa Aa ...

Amongst species of colonial snapping shrimp, the capacity for defense versus reproduction in queens varies with the level of cooperation, according to a study published March 14, 2018 in the ...

In the world of evolutionary research, scientists studying the evolution of eusocial societies have traditionally relied on information gathered from studying terrestrial insects. A group of ...

CAMBRIDGE, Mass. -- Scientists at Harvard University have sketched a new map of the "evolutionary labyrinth" species must traverse to reach eusociality, the rare but spectacularly successful social ...

For most of the past half century, much of sociobiological theory has focused on the phenomenon called eusociality, where adult members are divided into reproductive and (partially) non-reproductive ...

Naked mole-rats are one of the rare examples of eusocial mammals. Eusocial animal species are those in which a single female within the group is tasked with reproduction, along with a select group of ...

Colonies sustain themselves even when Messor structor males are absent. Workers possess 50 percent ancestry from each of the two species. The queen manipulates reproduction to maintain colony ...
