“Girls raised in dangerous, stressed or abusive environments are more likely to have a range of mental health issues, are typically more avoidant or reactive and are less able subsequently to parent as successfully as might otherwise have been the case.”

“The epidemiological evidence for sexual dimorphism in humans is extensive. Sexual dimorphism in body composition is already evident in infancy: males tend to be heavier than females at birth and have longer bodies and larger head circumferences. By early adulthood, sexual dimorphism in fat distribution is highly evident. These are the evolutionary roots of male sensitivity to visual cues of female physical attractiveness and also of women's motivation to display, preserve and improve their physical attractiveness and thus increase their perceived mate value. The extreme end of this adaptation gives rise to the risk of EDs in the modern environment.”

“To understand mismatch, we should note that yhe human lineage lived for 99% of its evolutionary history in relatively small, mobile, foraging, kin-based groups. It is under these conditions that human psychological mechanisms were shaped by selection. The seeds for mismatch were sown with the advent of agriculture, which resulted in permanently settled living around 10,000 - 20,000 years ago, and this radically altered the human physical and social environment with major implications for eating disorders EDs.”

“The Sexual Competition Hypothesis is based on the fact that throughout human evolutionary history the female shape has been a reliable indicator of the female's reproductive history and reproductive potential. The same is not true for men, where physical appearance, while relevant, is much less useful in assessing a man's reproductive potential. The visual signal for a female's peak reproductive potential in ancestral environments was the female's nubile shape, which was generally short-lived and declined with the repeated cycles of gestation and lactation.”

“We know that chronic high stress levels contribute to mental and physical disorders in later life; however, this process does not necessarily inhibit reproduction, and thus the cycle is perpetuated unless the environment changes as natural selection does not select for happiness, but only for survival and reproduction.”

“Female reproductive life history is linked to cardiovascular, metabolic, inflammatory and endocrine alterations to physiology in ways that have not only short-term but also long-term and, in some cases, permanent effects.”

“The grief triggered by the loss of loved ones does not appear to be an adaptation produced by natural selection as it does not appear to increase an individual's fitness in any way -at least not in non-social species. Depression caused by loss is more likely to be a by-product of the ability to form long-term attachment relationships. Grief is the price we have to pay when the attachment relationship is finally broken. This assumption is supported by the fact that a person may also experience symptoms of depression as a result of the death of their beloved dog, horse or other pet. The stronger the attachment, the longer the symptoms of depression last. On the other hand, the knowledge of the pain caused by the loss of an important person or pet makes us take more care of the people or pets that are important to us.”

“Evolution by natural selection tends generally to promote adaptations up to the edge of chaos -the boundary between order and disorder. Where all fitness-relevant regularities have been subsumed, what remains is noise, devoid of predictive utility.”

“The first, pian, is an ancient self-protective signal that enables animals to navigate fitness hazards in their external and internal environments. The aversiveness of pain is designed precisely to induce action to end or escape it. The second suicidogenic adaptation is the exceptional intellect of the mature brain, which is able to obey the imperative to escape pain, effectively but maladaptively, by terminating its own consciousness. These dual 'pain' and 'brain' conditions - motivation and means, respectively - are not only necessary for deliberate self-killing but sufficient.”

“In contemporary developed countries, loneliness has been described as an epidemic caused by the loss of traditional social connectivity and a reliance on technology. Therefore, it seems likely that the Alzheimer's disease risk factors of social isolation and loneliness were less prevalent in the past.”

“In good times, when material resources are abundant and women have plentiful social support, maternal negativity has little place in the lives of women. However, in times of scarcity and/or when women are unsupported, negative feelings can emerge to color the emotional palette and behavior of mothers.”

“The standard model of schooling in which 20 or more young people of the same age are taught in classrooms for about 5 hours a day on most days of the year for 10 years certainly runs counter some of our evolved behavioral strategies.”

“From the perspective of life history theory, a speeded-up metabolism, less trust, less relaxation and more suspicion and risk-taking might be adaptive for abusive homes or violent neighborhoods. In such environments there is little emotional security or expectation that things will work out well.”

“It is also important to note that not all pathological presentations are caused by the environment. A child may have underlying difficulties such as intellectual disabilities or other neurodevelopmental disorders. On the other hand, just because a child has survived unscathed does not mean that the environment was benign. We know that some children are naturally less sensitive to environmental influences and as such are more resilient to harsh environments.”

“Humans can survive in a wide range of physical environments, from the Arctic to rainforests to the Sahara. They can also survive in a wide range of emotional environments, from loving to neglectful to violent ones.”
