For example, sweet foods are usually associated with carbohydrates that are a great source of energy. Sour food allows us to identify food that has gone off and would therefore contain harmful bacteria. Salt food is vital for the function of our cells.
It claims that in cavemen times, thin people were less able to survive harsh winters because they had little adipose fat stores to supply energy when food was scarce in the winter. However, others who were able to store adipose fats when food was plentiful and had slow metabolic rates so that the fat could not be burnt easily were more able to survive because they had adapted to store more energy when food was scarce.
However, since our lifestyles and culture has changed with modern society, our body still stores adipose fats whilst our lives are more relaxed. It is much easier to access food compared to cavemen times they had to hunt constantly.
Since we move and exercise less, this adaptive response to survive has now manifested as the eating disorder of obesity. Pima Indians lifestyles used to be based on feast and famine. They would naturally put on weight over the summer when food was plentiful and got slimmer towards the summer months since their excess adipose fats were used up in the winter.
However, modern society caused their lifestyle to change, they became very dependent on government food supplies as a result of water supplies being diverted which caused food sources to move away animals moved to where water was plentiful.
As a result, their lives became more sedated and they developed a poor diet of carbs and fats. This supports the evolutionary approach because it demonstrates that since our lifestyles have become sedated and availability of food has become easier, we are able to put on more weight, therefore leading to obesity.
This supports the purpose of the thrifty gene and demonstrates what it would have been like in cavemen times. Therefore, the theory is deterministic because it suggests that we are victims of our ancestors adaptive to survive. This is a bad thing because it assumes we have no free will about how much we eat and we have no choice but to become obese because we are preparing for winter.
Another criticism of the evolutionary approach is that it only provides a small explanation of such a complex eating disorder. On its own, the evo approach does not give us a full picture as it is an incomplete explanation of obesity. You cannot get 50 stone from preparing for winter in modern society.
Another criticism of the evo approach is the inability to test it. Evidence had been gained from observations of species changing, fossils recorded and primate studies. Therefore it lacks external validity. However, it does make sense and is widely excepted that we have evolved to eat more when food is plentiful in order to survive harsh winters, so it has face validity.“evolution has given us the capacity” Evolution has not “given” us anything whatsoever.
Why is it that so many are unable to talk about evolutionary biology without the tacit assumption that it is some sort of intelligent being possessed of goals, will and even aesthetic judgement? Book of Mormon Problems.
LDS Church members are taught that the Book of Mormon (BOM) is scripture, as well as a true record of the inhabitants of the Americas from about BC to AD. Evolutionary psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective.
It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution.
