The body parts appear to be classed for compensation based on how much use they have in society. The higher the use; the higher the compensation cost. Loss of hearing, for example, as well as loss of testes and/or penis incur very high redress rates, because their loss will cause either danger or an inability to continue lineage, which was highly important in such a kin-based society. The tongue is also particularly high because, as with the ear, it would have formed the primary means of communication for the victim.
