Study Notes

Evolution, Selection, and Adaptations

Williams (1966) presented the gene-centered view of evolution, emphasizing that natural selection operates on individual genes rather than organisms or species.
Evolutionary adaptations are best understood at the level of genes, which drive the development of traits that enhance fitness.

Nettle (2018) identified patterns of behavior and social norms that are consistent across different cultures and can be explained through evolutionary theory.
Cultural universals highlight the influence of biological evolution on human behavior, suggesting that certain social behaviors are deeply rooted in our evolutionary past.
Plomin et al. (2016) highlighted ten robust findings from behavioral genetics, including the significant role of genetics in individual differences in behavior and cognitive abilities.
Genetic factors substantially contribute to social behaviors and cultural patterns, indicating a strong biological basis for these phenomena.

Sensation and Perception

New et al. (2007) found that humans have a heightened attention to animals compared to inanimate objects, which reflects ancestral priorities where detecting animals could be crucial for survival.
Human perceptual systems are biased towards detecting animals, indicating that these systems were shaped by evolutionary pressures to prioritize potential threats or resources in the environment.
New and German (2015) demonstrated that humans are more likely to notice spiders, an ancestral threat, even when attention is divided, compared to other non-threatening stimuli.

Learning

Petrinovich and Boles (1954) found that deprivation states, such as hunger, significantly influence learning and behavior, enhancing certain responses while inhibiting others.
Deprivation can alter learning processes and behavioral responses, demonstrating the impact of physiological states on behavior.
Sznycer et al. (2016) showed that longer coresidence with a mother increases altruism among siblings, indicating that perceived maternal investment affects sibling relationships.

Language

Pinker (2003) argued that language is an adaptation shaped by natural selection for specific functions in human evolution.
Language evolved as an adaptation for complex social interactions and cognitive tasks, enhancing communication and cooperation.

Rogers (1988) suggested that biological factors can limit the extent and manner in which cultural traits are adopted and transmitted.
Culture is influenced by biological constraints, indicating an interplay between genetic and cultural evolution in shaping human behavior.
Wertz and Wynn (2014) found that infants selectively learn about plant edibility by observing adults, suggesting an evolved mechanism for acquiring knowledge about safe foods.

Cognition

Cosmides et al. (2010) identified cognitive specializations for social exchange and cooperation, suggesting that human intelligence evolved to handle complex social interactions.
Human cognitive abilities are shaped by evolutionary pressures to solve social exchange problems, enhancing cooperation and social cohesion.
Kurzban et al. (2001) found that racial categorization can be reduced when coalitional information is made salient, suggesting that race is not a primary category but a cue for group membership.
Tooby (2020) argued that evolutionary psychology offers a coherent framework for understanding diverse social behaviors by linking them to adaptive problems.

Emotions

Sell et al. (2009) found that anger serves as a bargaining tool in social interactions, signaling strength and deterring others from exploiting the individual.
Anger is an evolved response to social threats, functioning to protect individuals' interests and maintain social equilibrium.
Sell et al. (2014) showed that the human anger face enhances cues of strength, making individuals appear more formidable to others.

Daly et al. (2001) found that higher income inequality correlates with higher homicide rates in Canada and the United States, suggesting socio-economic factors influence violence.
Socioeconomic disparities contribute to social pathologies such as violence, highlighting the impact of environmental conditions on antisocial behavior.
Daly and Wilson (2001) found that stepchildren are more likely to suffer from neglect and abuse than biological children, consistent with evolutionary predictions of nepotism.
