Inclusive fitness: a theory to explain cases when an animal behaves in such a way as to promote the advantages of other members of the species not its direct descendants at the expense of its own (Hamilton 1963, p. 354).
Alarm calling is an inherently dangerous behavior, and its adaptive function was poorly understood for decades. Calling individuals suffer direct costs (e.g., predation), and so the ultimate function was initially described as a residual behavior thought to have evolved as a signal from parents to offspring (Maynard-Smith 1965). Subsequent theories described the behavior as individually selective.
