M. Arnay-de-la-rosa et al., Auricular exostoses among the prehistoric population of different islands of the Canary archipelago, ANN OTOL RH, 110(11), 2001, pp. 1080-1083
It is generally believed that auricular exostoses are due to prolonged expo
sure to cold water, so their existence in ancient remains may inform us abo
ut economic activities in the past. This study was performed to analyze the
prevalence of auricular exostoses among 150 pre-Hispanic individuals of di
fferent islands of the Canary archipelago. Individuals from Gran Canaria (6
/26), Fuerteventura (1/15), and Tenerife (2/64), but not from El Hierro (0/
45), showed auricular exostoses. thus supporting the hypothesis of a greate
r reliance on fishing and shellfishing in the former 3 islands.
