The evolutionary explanation assumes that most behaviours happen to be learned through the process of normal selection as humans have got adapted behaviours that are advantageous to either endurance or duplication. Surbey argues that teenagers girls wishing to control their body weight represents an major adaption in which ancestral women would postpone the start sexual growth in response to cues about the likelihood of poor reproductive accomplishment. This is adaptive because it in that case enables the woman to avoid having a baby at a time mainly because it would have been dangerous to obtain children while mortality costs during child birth would be quite high, thus allowing survivability.
This theory is based off of the fact that several species have got similar skills in that they can delay or suppress puberty in females when they are subjugated to stress and/or in poor condition. Surbey then argues that beoing underweight is a ‘disordered variant’ in the ability of females to alter the timings of reproduction at a time whenever they feel that they’re unable to manage becoming a female. This is then simply supported by the simple fact that the onset of puberty can be delayed in prepubescent girls with anorexia and that amenorrhoea is a common characteristic of the disorder. This is due to sexual maturity is suspended in these ladies until the environment is more appropriate. This facilitates the theory since it would explain why anorexic would be adaptive in delaying puberty.
A positive for the Reproductive : Suppression theory is that this explains how come most Beoing underweight sufferers will be female, nonetheless it does not describe why there would be any men sufferers in any way. If the theory was correct, it would imply that only females should experience Anorexia. Nevertheless , Holland et al supports the idea that Anorexic behaviour patterns enabled affected individuals to survive to reproduce and pass on behaviours genetically while she identified that there is a 56% concordance rate in anorexia between MZ baby twins and only seven percent in DZ twins.
One issue with this theory is that it can be deterministic. Which means that anorexia is usually governed by forces unmanageable to the specific as it is passed down to all of them through organic selection and is in their biology, meaning that there is a lack of free of charge will to battle against that.
One other issue with this kind of theory is the fact is reductionist. This means that they are really simplifying complicated human behaviors into a straightforward explanation, in such a case evolution. This is due to the theory will not consider some other explanations to anorexia, other than evolution. One other theory that may explain anorexia is the psychodynamic theory submit by Bruch which suggests that childhood morsure and conflicts may be the cause.
