| Behavioral genetics | The study of how genes and environment interact to influence behavior. |
| Error management theory (EMT) | The idea that human decision-making evolved to minimize costly errors, even if that means making more harmless ones. |
| Heritability coefficient | A statistic (ranging from 0 to 1) that measures how much of the variation in a trait among people is due to genetic differences. |
| Intersexual selection | A form of sexual selection where individuals of one sex (usually females) choose mates based on certain desirable traits. |
| Intrasexual competition | A form of sexual selection involving competition among members of the same sex (usually males) for access to mates. |
| Psychological adaptations | Evolved mental mechanisms that help humans solve recurring problems related to survival or reproduction. |
| Quantitative genetics | The study of how genetic and environmental factors contribute to individual differences in traits that vary continuously (like height or intelligence). |
| Sexual selection | A type of natural selection that occurs because certain traits increase an individual’s chances of mating and reproducing. |
| Sexual strategies theory | A theory proposing that humans have evolved different mating strategies (short-term and long-term) depending on context, sex, and individual differences. |
