The process where organisms better adapted to their environment tend to survive and produce more offspring.

Differences in physical characteristics between males and females of the same species.

The ability of a trait to be passed down from parents to offspring.

A population grows at an ever-increasing rate.

Differences in genes among individuals of a species.

Different forms of a gene.

The genetic makeup of an organism.

A subfield of evolutionary psychology that uses comparisons across species, cultures, and developmental stages to understand the evolution of human behavior.

A type of sexual selection where individuals of one sex choose mates based on certain traits or qualities.

The theory that the sex which invests more in offspring (typically females) will be more selective in choosing a mate.

A theory proposing that individuals prefer mates with different MHC genes, which may increase offspring immune system diversity.

Evolutionary psychology focuses on innate psychological differences driven by evolutionary adaptations, while social psychology emphasizes the role of social structures and cultural influences on behavior.

A gene's self-interest is to be passed on to future generations. This means maximizing the chance of its survival and replication.

Biological fitness is a measure of an organism's reproductive success, meaning how effectively it passes its genes to the next generation.

Intersexual selection involves preferential mate choice. One sex, usually females, selects a mate based on certain traits.

Gametic investment refers to the energy and resources an organism invests in producing offspring.

Intrasexual selection occurs when members of the same sex compete for access to mates. This can involve status displays, physical combat, or resource control.

The Cognitive Revolution, starting roughly 70,000 years ago, marked a significant shift in human intelligence and abilities. It resulted in advanced toolmaking, language development, and symbolic thinking.

The Environment of Evolutionary Adaptiveness (EEA) refers to the environment in which a species evolved and developed its adaptations. For humans, it's thought to be the African savanna during the hunter-gatherer period.

Mismatch examples refer to situations where our modern environment doesn't match the EEA, leading to problems. Examples include fear of modern dangers, cravings for unhealthy foods, and aggression in modern society.

Evolutionary psychology aims to understand the human mind by studying how our cognitive abilities and behaviors evolved to solve adaptive problems faced by our ancestors.

The 5th principle states that our modern brains are shaped by the challenges of our hunter-gatherer ancestors, meaning our minds may not be perfectly suited for the modern world.
