As Wilson points out, "There is an a priori reason for believing campsites were the crucial adaptation on the path to eusociality
: campsites are in essence nests made by humans.
The seeds of eusociality
were planted in our species long before the dawn of agriculture, but once that happened and our numbers increased, all hell broke loose, so to speak.

. Nature, 466, 1057-1062.
In a second mathematical analysis, the team investigated how eusociality
could evolve through standard natural selection.
There is no general eusociality
between components on the level of the ecosystem, although there is differential fitness, and this can be important at different stages of succession and community assembly.
Andersson (1984) reviewed the literature for the evolution of eusociality
in insects and vertebrates, noting that several traits, including parental manipulation, appear to be preconditions for advanced sociality in both of these groups.
Others include R-selection (prolific breeding), the production of secondary metabolites (such as venoms), segmentation, eusociality
The primitively social bees are of particular interest for studies of the evolution of sociality in insects, since they have members which are solitary, grading through various levels of complexity to eusociality
. Here, eusociality
is defined as the presence within a colony of overlapping generations of adults that cooperate in caring for a brood produced by a subset of colony members.
Brittany Sue Mason, Mackenzie Lovegrove's project involves trying to understand how honeybees evolved "eusociality
"--the social structure where one female reproduces and the others rear her offspring.
It has been speculated that eusociality
or haplodiploidy might have an impact on Wolbachia infection [50, 55], but such mechanisms have never been confirmed.
