“…Direct evidence for the action of stabilizing selection in humans is scarcer. Birth weight is one reported example of a human trait under stabilizing selection (22), although the intensity of selection has decreased in postindustrial societies (23). A twin study of female reproductive life-history traits showed evidence for a phenotypic optimum for age at menarche (14).…”

Modern molecular genetic datasets, primarily collected to study the biology of human health and disease, can be used to directly measure the action of natural selection and reveal important features of contemporary human evolution. Here we leverage the UK Biobank data to test for the presence of linear and nonlinear natural selection in a contemporary population of the United Kingdom. We obtain phenotypic and genetic evidence consistent with the action of linear/directional selection. Phenotypic evidence suggests that stabilizing selection, which acts to reduce variance in the population without necessarily modifying the population mean, is widespread and relatively weak in comparison with estimates from other species.

“…Human history has shown that, when average infant birth weights are too small or too large, infant mortality is high. As a result, a nice, stable intermediary infant birth weight of 3.5 kg (7–8 lbs) has become the norm and has remained relatively constant over time (Sanjak et al , 2018; Ulizzi and Terrenato, 1992). Similarly, human height continued to increase across subsequent generations (Garcia and Quintana-Domeque, 2007).…”

Purpose This paper aims to review organizational studies literature and related fields to explore the parallel between organizations and organisms in dealing with change. Design/methodology/approach The authors reviewed the literature to explore organizational change theories. Additionally, they referred to biological studies to explore the connection between organizations and organisms. Findings To cope successfully with change, organizations need to be aware of the critical, vulnerable points that may endanger their survival. These vulnerabilities can arise from external or internal factors or both. Organizational leaders, being aware of these criticalities, can act swiftly to deal with threats while keeping an eye on available opportunities. Research limitations/implications Future research could be conducted on understanding the elements of biological transformations through an in-depth study focused on species that have undergone frequent mutations and adaptations. It is hoped that HRD researchers, especially organization development (OD) theorists and practitioners, can build upon the ideas presented in this article. Practical implications The review and analysis can open doors for HRD practitioners to seek a better understanding of biological transformations, while enabling them to borrow ideas to be used in leading organizational change and design successful organizational change. Originality/value In this paper, the authors selected organizational theories to outline parallels between organizations and organisms to emphasize what organizations can learn from the success of organisms changing over billions of years. Thus, this paper uniquely contributes to HRD literature by encouraging OD researchers to conduct more interdisciplinary research. Most importantly, this paper contributes to understanding the underlying theories in HRD/OD.

“…Stabilizing selection, in particular, is potentially widespread (Sanjak et al, 2018) and may have contributed to the among‐group differentiation in many skeletal traits (Roseman & Auerbach, 2015). However, direct evidence of stabilizing selection (Nettle, 2002a; Sanjak et al, 2018; Stearns et al, 2010; Stulp et al, 2015; Ulizzi & Terrenato, 1992) and disruptive selection (Beauchamp, 2016; Nettle, 2002b) in humans is rare and is most commonly found with life‐history traits associated with reproductive success. Moreover, throughout the following sections, we discuss phenotypic plasticity as both the ability of a genotype to produce different phenotypes across environments (i.e., genotype‐environment interaction) (Via & Lande, 1985) and the nonheritable plastic response to short‐term environmental conditions (e.g., nutritional differences) that occur during one's lifetime.…”

The discipline of forensic anthropology has been critiqued for its lack of a theoretical basis. In response, practitioners often assert that their analyses are implicitly grounded in evolutionary theory. However, the nature of this theoretical grounding is little discussed in the forensic anthropology literature, beyond, for example, statements indicating that sex‐based pelvic differences have evolved in response to increasing encephalization within the genus Homo, or that clinal variation in features like limb proportions have evolved within our species due to environmental pressures that differ on a gradient. Further, while the role of natural selection in shaping the morphologies analyzed in biological profile estimation is undeniable, adaptation in response to environmental pressures does not explain all variation within our species. Evolutionary theory is not monolithic; different perspectives on the primacy of functional adaptation versus factors like drift and phenotypic plasticity lead to differences in skeletal interpretations and lead researchers to novel approaches in creating new or improving current methodologies. Various theoretical perspectives underpin forensic anthropological analyses, and in order for forensic anthropology to be truly grounded in evolutionary theory, these theoretical perspectives must be not only made explicit but also interrogated in terms of how they inform forensic anthropological interpretations.
