“…Hormones are a key factor in the realization of individualized niches. Their crucial role is particularly evident in view of the current discussion that selection might act on the (endocrine) mechanisms of behavior rather than on the behavioral traits themselves [21].…”

“…In particular, epigenetic explanations centering on specific genes should be interpreted carefully, as associations among single genes and behaviors often do not replicate in studies of humans and NHPs (see above). Given the increasing general understanding of genome-wide DNA methylation patterns in humans and NHPs (Lea et al 2016(Lea et al , 2018, the role of epigenetics in personality development could become an interesting area of future research (Trillmich et al 2018).…”

As is the case for humans, it has long been thought that nonhuman primates can be described in terms of their personality. Scientific observations that support this view include the presence of individual differences in social behavior and that they are relatively stable throughout life. Consequently, individuals are constrained in their behavioral flexibility when dealing with various environmental challenges. Still, the variation among individuals during development suggests that the environment influences how primates behave. Research in fields including psychology, behavior genetics, and behavioral ecology have tried to identify the mechanisms responsible for this interplay of behavioral stability and change. In this review we integrate theories and findings from research on humans and nonhuman primates that highlight how and to what extent genetic and environmental contributions shape the development of social behavior. To do so we first provide an overview and define what is meant by mean level and rank-order change of behavior. We then review explanations of behavioral stability and change, focusing on the role of genetic effects, how environmental circumstances influence behavioral variation throughout development, and how genetic and environmental influences may interact to produce this variation. Finally, we point to future research directions that could help us to further understand the development of social behavior in primates from within a behavior genetics framework.

“…Even individuals of identical genotype differ in their behaviour [1]. This finding should not surprise since behaviour and its underlying neural structures are constantly modified through interactions with the social and physical environment during the course of life [2,3]. Such malleability, known as behavioural plasticity, enables organisms to adjust their responses across environments [4,5].…”

The adaptive shaping of social behavioural phenotypes during adolescence

Developmental behavioural plasticity is a process by which organisms can alter development of their behavioural phenotype to be better adapted to the environment encountered later in life. This ‘shaping’ process depends on the presence of reliable cues by which predictions can be made. It is now established that cues detected by the mother can be used (primarily via hormones prenatally and maternal behaviour in the early postnatal stage) to shape the behavioural phenotype of her offspring. However, it is becoming increasingly clear that adolescence is another period in which conditions are well-suited for such shaping to occur. We review here how mammalian social behaviour may be shaped in adolescence. We identify limited extant examples, briefly discuss underlying mechanisms, and provide evidence that observed changes are indeed adaptive. We contend that while plasticity diminishes with age, the shaping of the behavioural phenotype in adolescence offers several advantages, including that adolescence is closer to the onset of mating than are earlier phases of life; that unlike earlier phases, information is obtained directly from the environment rather than mediated by the mother; and unlike later in adulthood, there is substantial underlying neural plasticity associated with development to support behavioural change. We also consider conditions that favour the occurrence of social behaviour plasticity during adolescence, including a high degree of sociality and a prolonged developmental period and the implication of these conditions for the occurrence of sex differences in the shaping process.
