“…To explain how and why organisms, including humans, allocate energy, time, and resources across their lifetime, evolutionary biologists and behavioral ecologists developed life history theory (Charnov, 1993; Daan & Tinbergen, 1997; Horn, 1978; Low, 2000; Roff, 1992; Stearns, 1992). This framework has accrued copious empirical support in research on animal behavior, and it has become increasingly important in research within human behavioral ecology, anthropology, and developmental psychology (see, e.g., Belsky, Steinberg, & Draper, 1991; Chisholm, 1993; Davis & Werre, 2008; Del Giudice, 2009; Eibl-Eibesfeldt, 1989; Ellis, 2004; Ellis et al, 2009; Figueredo et al, 2006; Hill & Kaplan, 1999; Horn & Rubenstein, 1984; Kaplan & Gangestad, 2005; Low, Simon, & Anderson, 2002; Promislow & Harvey, 1990; Quinlan, 2007; Walker, Gurven, Burger, & Hamilton, 2008). …”
