found various ways to use leaves in their everyday lives including clothing, medicine, and to sleep on. Anthropologist A.R. Radcliffe Brown argued that the Andamanese had no government and made decisions by group consensus. Religion The native Andamanese religion and belief system is a form of animism. Ancestor worship is an important element in the religious traditions of the Andaman islands. Andamanese Mythology held that humans emerged from split bamboo, whereas the women were fashioned from clay. One version found by Alfred Reginald Radcliffe-Brown held that the first man died and went to heaven, a pleasurable world, but this blissful period ended due to breaking a food taboo, specifically eating the forbidden vegetables in the Puluga's garden. Thus Catastrophe ensued, and eventually the people grew overpopulated and didn't follow Puluga's laws, and hence there was a Great Flood that left four survivors, who lost their fire. Physical appearance Phenotype Negritos, specifically Andamanese, are grouped together by phenotype and anthropological features. Three physical features that distinguish the Andaman islanders include: skin colour, hair, and stature. Those of the Andaman islands have dark skin, are short in stature, and have "frizzy" hair, while displaying "Asiatic facial features". Dental morphology Dental characteristics also group the Andamanese between Negrito and East-Asian samples. When comparing dental morphology the focus is on overall size and tooth shape. To measure the size and shape, Penrose's size and shape statistic is used. To calculate tooth size, the sum of the tooth area is taken. Factor analysis is applied to tooth size to achieve tooth shape. Results have shown that the dental morphology of Andaman Islanders resembles that of tribal populations of South Asia (Adivasi) the most, followed by Philippine Negrito groups, contemporary Southeast Asians, and East Asians. The tooth size of the Andamanese was found to be most similar to that of Han Chinese and Japanese. Genetics Genetic analysis, both of nuclear DNA and mitochondrial DNA provide information about the origins of the Andamanese. The Andamanese are most genetically similar to the Malaysian Negrito tribes, followed by contemporary East Asian people. Genetic variation The Andamanese show a very small genetic variation, which is indicative of populations that have experienced a population bottleneck and then developed in isolation for a long period. An allele has been discovered among the Jarawas that is found nowhere else in the world. Blood samples of 116 Jarawas were collected and tested for Duffy
