 Responding to the challenge posed by these proposals, and noting both the absence of any definition of performance and any attention to the historical facts about the ways the relevant practices actually developed (see  §3.1  below), it has been argued that the most plausible way to characterize “performance” has its roots in standard ethnological and ethological theories, and characterizes “performance” as a kind of “display behavior” that is exhibited by members of various species, including our own (Hamilton 2013). In this account, however, performance is not an alternative to acting but more like acting’s “genus” to which it corresponds as a “species”.
