Primates are dependent upon a strong and stable attachment. In a recent study Infant and maternal behaviors were explained of how they became co-adapted during evolution. Old-fashioned societies and almost certainly throughout human evolution, culturally successful adults have control of valuable resources and greater social influences which are linked to better health, a longer life span and healthier children. (Bjorklund & Yunger, 2001). From a life history view, parental …show more content…
Examples include children who are living in unstable, high stress homes with few or no resources, attain puberty at an early age, invest less in their offspring than children from stable, low stress homes (Curly, 2011). A baby’s attachment with the caregiver may have served to increase that infant’s survival during a time in ontogeny ensuring close proximity to mutual affection (Curly, 2011). It has been reported that the OPRMI gene has been associated with the behavioral variation in infant attachment in rhesus macaca which shows a co-adaption of the gene OPRMI in the framework of mother infant relationships. Opioids are said to be important controllers of maternal behavior in offspring by matching the onset of maternal behavior with parturition and maternal affect, during evolution, the function of opioids have achieved the additional role of facilitating both infant attachment and maternal care (Curly, …show more content…
Such risk taking is said to enhance the social status of young men and make them more attractive sexual partners. Males were chosen to traits that relate to dominance and social status and have some involvement of indirect resources such as food and protection of the offspring which increase with education and socio economic status, whereas females have traits that contribute to signaling reproductive value and potential nurturance toward their offspring (Kenrick, Sadalla, Groth, & Trost,
