With all the supportgiven by these people who have immensely helped in developing my understanding andknowledge of the topic selected in the dissertation.ABSTRACT
In thehunter-gatherer society most of the foods is obtained through wild plants and fromwild animals. The Hadza is one such hunter gatherer society, whose diet includes grasses, tubers,fruits, seeds and nuts. Due to the lack of having skills in relation to killing larger animals,Hadzatypically procure meat from smaller to larger game. This study investigated whether heightof Hadza adultswho attended school as a child varies from those who did not. The primary datapertaining to height and schooling were gathered by other researchersover several years. Fromthis, individuals aged over 20 were selected and – for both males and females – height comparedbetween schooled and non-schooled groups. In the case of Hadzamale adults,nosignificantdifference was found. However, in the context of female adults, there was evidencethat schooling was associated with an increase in height.Key Words;Hunter-gatherers, mate choices, body size or height, mortality, demography.

CHAPTER 1: INTRODUCTIONOverview of Hadza heightThe Hadza are an indigenous group who live in north-central Tanzania near LakeEyasi.They are believed to be one of the oldest tribe remains in the region. Approximately, all Hadzapeople highly rely on gathering and hunting for the majority of their diet (Sassaman, 2004). Hadzamales comeunder the category of leanest Africans. Due to the larger muscle massHadza malesare above the average in weight for height.In the study, author presented that due to theinequality of sexes in feeding during growth stage differences take place in the height aspect(Hiernaux and Hartono, 1980). From assessment, it has found that height is one of the mainfactors which closely influencehuman mate preferences and choices. In western societies,women prefer to marry with themen who are taller in comparison to themselves(Sorokowskiet.al., 2017). However,in the context of non-western societies such asHadzadifferences in the size or appearance between the sexes of individuals takeplace(Sorokowskiet.al., 2017). InHadza,preferences for sexual dimorphism in stature and actualSDS (sexual dimorphism stature) are highly correlated in the context of both men andwomen.Hence, height differences with the partners among Hadzatake place on the basis of theirpreferences. Further, in the Hadza, population mating is random in relation to the size or heightaspects (Sear and Marlowe, 2009). It presents that matting preferences among hadza are notinfluenced as per height.This study also indicated that at the time of choosing a mate,size andstrength are not considered by Hadza people.Heightusually indicates health, productivity andoverall quality.However,among Hadzapeople matting patternlackssize aspects as well as notidentical across all the population.This study will assess whether attending school has an impact on height of adults amongthe Hadza.There are several factors which in turn have significant impact on the height ofindividuals such as diet, nutritional aspects and physical activities etc (Urlacher and Kramer,2018). Moreover nutritional aspects have some influence on health and thereby affect growth ofchildren. Hunter-gatherer describes a society, where most or all of the foods is obtained fromwild plants or hunting wild animals.By contrast, agricultural societies are highly reliant ondomesticated species (Samson and et.al., 2017). Hence, hunting and gathering people depend1
primarily on wild food for subsistence. Strategies of hunter gatherers are highly influenced bylocal environment. Hadzadiet include grasses, tubers, fruits, seeds and nuts. Hence, diet of huntergatherers can say to be good as it includes enough protein, fat as well as other healthyelements(Berbesque, 2009). However, availability of food from plants and others arehighlyaffected by seasonal aspects.Children who go to school are provided with several nutritionalsefoodsthat contribute to their growth and development. In contrast to this, children who do notgo to the school havelimited diet plan or food options (Jones and Marlowe, 2002). Further,through investigation, it has been assessed that, as per Marlowe (2002), enthusiasm level of themfor eating is highly matched by an abundance of ingredients around them. Hence, tracking andforaging skills are needed to find them. Along with this, it has identified from the evaluation thathunter gatherers shares everything as theirs is an egalitarian society.Past studies conducted on several countries show that the relationship between height andquality of diet is significant and positive considering several factors such as nutritional aspects,lifestyle etc. It has been revealed that the Hadza diet contains great source of fibre, potassium aswell as water but it is seasonally lean in lipids; this in turnplaces has a negative impact on thegrowth of children (Senghor and et.al., 2018). Protein,carbohydratesandfatsare the mainelements that contribute in the growth of children.Moreover, carbohydrate and fats providechildren with energy for growing and physical activities. In addition to this, protein builds,maintains and repair body tissue so that it is considered as vital element for children growth. Dietproducts which are undertaken by Hadza peoplecontainthequantity of fat and proteins. Further,honey is highly used by Hadza people, and this contains low protein and fat, 400 Kcal / 100g(Murray and et.al., 2001). In addition to this, drupes and berries are low in fat as well protein.Thus, considering all aspects it can be presented that Hadza people or children diet plan hassignificant impact on their growth. Aim and objectivesThe aim of this study is toanalyse whetherthe height of adults who attended school as achild differs from that of adults that did not attend school as a child. H0 (Null hypothesis): There will be no difference in height between adult Hadza that attendedschool as children and those that did not attend school.2
