If we want to understand the fundamental principles and mechanisms underlying collective action, an excellent place to start is with groups of just two, for several reasons.

(5) Groups of two can be fraternal, made up of genetically related individuals, or egalitarian, made up of genetically unrelated individuals, allowing a comprehensive understanding of the possible factors facilitating social behavior.

There are only two members to form pairwise interactions and respond to the external environment. If common principles underlie the formation of the group of two, then the dyad forms the foundation of all group structures and could be a common framework to understand both group behavior and history.

In Protestant Christianity, some denominations fragmented and later merged again in response to internal and external factors. Sexual reproduction is also a type of merger in which egg and sperm unite to form a single zygote, a new and novel individual.

The dyad can also include unique evolutionary processes in which both members are changed irrevocably by selection pressures. In a "red queen" evolutionary arms race between a pathogen and a host, strong selection can ensure that both members of the group change dramatically through mutation accumulation as each tries to outmaneuver the offensive and defensive strategies of the other.

In vitro viral capsid and cytoskeletal assembly assays can measure assembly and disassembly of complex biochemical groups from their building blocks. Repeated and robust experiments with these new tools should reveal the fundamental building blocks of more complex groups at a variety of scales, potentially boosting the importance of the dyad in group formation and maintenance.
