It is argued that sex differences in attachment emerge in middle childhood, have adaptive significance in both children and adults, and are part of sex -
specific life history strategies.
In particular, my work explores the reproductive and
life history strategies of males and females in primate societies, using both observational and experimental data.
«Negative frequency dependence is the idea that selection favors the
rarest life history strategies,» said Michael Blouin, a professor of integrative biology at Oregon State University.
This phenomenon is explained by negative frequency dependence: the idea that the rarer a
particular life history strategy used by a species is, the higher its fitness will be.
Although we applaud Del Giudice for calling attention to the problem, we regret that he does not sufficiently specify how attachment styles serve as an integral part of a
coordinate life history strategy for either sex.
Higher unpredictable care / support scores were associated with a younger age of having a first child, marrying, and starting a family, indicating
fast life history strategies.
These environmental cues cause the individual to
adjust life history strategies accordingly and adopt fast life cycle traits, such as early puberty, early onset of sexual activity, teenage pregnancy, and lower life expectancy (Belsky, Schlomer, & Ellis, 2012; Ellis et al., 2009).
Sex differences in the development of attachment can be fruitfully integrated within the broader framework of adaptive plasticity
in life history strategies, thus contributing to a coherent evolutionary theory of human development.
«The tolerance of herring larvae to pH changes could be due to
their life history strategy.
Life history strategies to increase reproductive success are termed as reproductive modes.
They used game theory, mathematical and computer models to show that one
life history strategy would dominate in the absence of negative frequency dependence.
But if it's low enough, and if there's a fitness benefit, which we've shown there is, these two
life history strategies can coexist,» Christie said.
Del Giudice addresses a complex and pertinent theoretical issue: the evolutionary adaptiveness of sex differences in attachment styles in relation to
life history strategy.
The impact of stress on
the life history strategies of African American adolescents: cognitions, genetic moderation, and the role of discrimination.
The K factor: individual differences in
life history strategy.
The present study sought to investigate whether perceived family unpredictability affects the development of
life history strategies in both the reproductive and somatic domains by evaluating the ages at which life milestones occurred.
