evolutionary explanations AO1 Flashcards
how do evolutionary approaches explain human behaviour
in terms of adaptiveness and reproductive success
what would the evolutionary explanation say behaviours are for
genetically inherited for survival or reproduction
what is natural selection
behaviors that help humans adapt to and survive in the environment
what is sexual selection
behaviors that help attract a mate and produce healthy offspring
what is anisogamy
explains differences in male and female sex cells
what does anisogamy lead to
different reproductive strategies
how does anisogamy describe sperm cells
produced in large quantities, replenished quickly, and available throughout life, allowing males to mate with many females
how does anisogamy describe egg cells
produced in limited numbers, requiring significant energy, and only during certain fertile years, making reproduction more costly
as a result of anisogamy, what mating strategy do males adapt
seek to increase reproductive success by mating with multiple females (uncertainty of paternity)
as a result of anisogamy, what mating strategy do females adapt
seek committed partners who will provide resources and support, ensuring the survival of their offspring
what was the sample in Buss’s study
10,000 adults in 33 countries
what was the aim of buss research
find differences between male and female mating strategies
what did buss find
Males: preferred younger mates and focused on signs of a female’s reproductive ability, such as: modesty, attractiveness
Females: universally valued resource-related traits in a partner, such as: ambition, intelligence and good financial prospects
what do buss’s findings show about evolution theory
align with the evolutionary theories, showing that females prioritize long-term support, while males prioritize physical traits linked to fertility
what is inter sexual selection
females, due to their higher investment in reproduction (time, energy, and resources), need to be more selective when choosing a mate (female choosiness)
