The Aranda are a much-studied tribal group in Australia, mainly because they are centred on Alice Springs, the only sizeable post-colonial town in central Australia. Their territory includes Mt Zeil, the tallest mountain in central Australia, and they consist of five tribes:

  • Wongkatjeri or I:lma in the South;

  • Mbenderinga or Aluna in the West;

  • Aldolanga or Karo:linga in the East;

  • Ko:ang in the Central area;

  • and “True” Aranda in the North.

The Aranda are divided into two moieties, as are all tribes across Australia. The moiety system is a simple method of ensuring gene mixing: children are always in the same moiety as their mother, so must marry into the other moiety. It is forbidden for people of the same moiety to marry, and for this reason the moiety system has been linked with incest avoidance.

The Aranda have a second gene mixing mechanism, which overlays the moiety system and which is usually referred to by the term sections. The use of sections imposes a second limitation on “marriage”: it is forbidden for members of the same section to marry, and often members of one section are limited in the choice of their spouses to only one other section. Thus, while the moiety system prevents intergenerational incest, the section system prevents intragenerational incest.

All tribes across Australia have a section system, but it varies from a simple two-section model through three sections and up to the Aranda four section model. The more sections there are, the greater the degree of incest-avoidance.

Another level of division in Aranda society (and once gain found across Australia) is the totem, which affects hunting and dietary rights, and may be implicated in territoriality. Spencer and Gillen describe nine totems in each moiety:

The ceremonies we witnessed were connected with the following totems:- (Ngapa-yurrkkurla-R) a great mythic snake; Thalaualla, the black snake; Muntikera, the carpet snake; Tjudia, the deaf adder; Kutnakitji, a green snake; Emu; Watjinga, the Echidna; Lunkulungu, white ant eggs; and Thankatherta, a snake, all of which belonged to the Uluuru moiety. Of those belonging to the Kingilli moiety we saw Utu, wind; Itjilpi, ant; Lirripitli, a lizard; Thaballa, laughing boy; Namini-patunga, a little bird; Tjalikippa, the white cockatoo; Karinji, the jabiru; Winithonguru, the native cat; and Walunkun, fire. (Spencer and Gillen, The Native Tribes of Central Australia, Macmillan, London. (1904) 1969. pp298-299)

However, it must be emphasised that not all the totems are present in one tribe. Also, the role of totems in the Aranda sectional model is unclear: in some other tribes the totems correspond to sections or to sections within moieties, but this is obviously not the case for the Aranda.

The Aranda section-moiety division of society is a very efficient way of gene mixing. For instance, a person always has one grandparent in each section; and it is impossible for brothers and sisters to marry, or for a parent to marry their offspring. The only close marriage allowed is for a male to marry his paternal grandmother – and, in light of the age difference, this is unlikely to be a very fertile union.
