                     What is eusocial 
behavior?
INTRODUCTION
Advanced social behavior that entails nest 
sharing; division of labor including a caste system 
with sterile worker caste caring for offspring of 
the reproductive caste; and overlapping 
generations so that offspring assist parents.

EUSOCIAL 
The truly social insects displaying eusocial 
behavior, include the termites, the ants, and 
some of the highly organized bees and wasps.

DEFINITION
Eusociality, the highest level of organization of 
sociality, is defined by the following 
characteristics: cooperative brood care, 
overlapping generations within a colony of adults, 
and a division of labor into reproductive and 
nonreproductive groups.

HISTORY
The term "eusocial" was introduced in 1966 by 
Suzanne Batra, who used it to describe nesting 
behavior in Halictine bees.
Batra observed the cooperative behavior of the 
bees, males and females alike, as they took 
responsibility for at least one duty (i.e., 
burrowing, cell construction, oviposition) within 
the colony.

ACTIVITY
The cooperativeness was essential as the activity 
of one labor division greatly influenced the 
activity of another.

SURVIVAL
Eusocial colonies can be viewed as 
superorganisms, with individual castes being 
analogous to different tissue or cell types in a 
multicellular organism castes fulfill a specific role 
that contributes to the functioning and survival of 
the whole colony, while also being incapable of 
independent survival outside the colony.

IN HUMANS
An early 21st century debate focused on whether 
humans are prosocial or eusocial. Wilson called 
humans eusocial apes, arguing for similarities to 
ants, and observing that early hominins 
cooperated to rear their children while other 
members of the same group hunted and foraged.

IN NONHUMAN MAMMALS
Among mammals, eusociality is known in two 
species in the Phiomorpha, the naked mole-rat 
and the Damaraland mole-rat (Fukomys 
damarensis), both of which are highly inbred.
