“…The phylogenetic perspective maintains that when examining a particular evolved adaptation, researchers should consider the timing of its evolution in relation to other adaptations. One particularly helpful concept emerging from this theoretical orientation is the adaptive workaround : When adaptations conflict with one another, those that evolved later in a species’ evolutionary history will mute or refocus the function of those that evolved earlier (Eastwick & Durante, 2015). The present research provides evidence for an adaptive workaround by demonstrating that in-group membership on the basis of symbolic cues (i.e., a recent human adaptation) moderates ovulatory shift effects (i.e., an older adaptation).…”

The ability to differentiate in-group from out-group members on the basis of symbolic cues may be unique to Homo sapiens. The current research examined whether meaningful cues of in-group status moderate ovulatory shifts—a psychological adaptation that likely evolved earlier in humans’ evolutionary timeline. Four studies demonstrated that men were more attracted to fertile than nonfertile women’s voices only when men were evaluating in-group members. In Study 1, the fertility of Caucasian, but not Hispanic, women’s voices positively predicted 92 Caucasian male students’ attraction ratings. Study 2a ( N = 56) replicated this effect among older participants, and Study 2b ( N = 233) included a public preregistration and replicated it again. Study 3 replicated the effect in a sample of 47 Caucasian male students, and an experimental manipulation of the targets’ school membership produced a conceptual replication. These results stress the utility of considering the phylogeny of human evolution when testing evolutionary hypotheses.

“…A estas habilidades se asocian el surgimiento de la cultura y de la planificación a futuro, que junto con el lenguaje y el pensamiento simbólico conforman lo que en la literatura científica se menciona como modernidad comportamental. En este contexto el autocontrol y la regulación emocional habrían funcionado como herramientas muy importantes en pos de la conformación de grupos culturales y cooperativos estables (Cortina, 2017;Eastwick & Durante, 2015). Pero para que esto se diera lugar esas características cognitivas tendrían que haber surgido mucho tiempo antes, a través de procesos de selección natural.…”
