The Evolution of Age-Structured Marriage Functions: It Takes Two to Tango

摘要: Two-sex marriages in socially structured populations can be characterized as multiplicative perturbations of heterosexually random, or proportionate, mixing (Castillo-Chavez & Busenberg 1991). Such are expressed terms preferences, affinities, males for females, and vice versa. Male female preferences obviously not independent, since they depend on the availability male behavioral classes. Knowledge one gender characterize both genders populations; other words, “it takes two to tango.” This is basic content T3 Theorem. Different sets that is, distinct classes, may give rise identical mating probabilities, determinants “ phenotypes” (Hsu Schmitz 1994; Hsu et al. 1993). Hence, different individual decisions lead social dynamics, a fact well established genetics. The importance incorporation systems at population level neglected but central area evolutionary biology.
