Caption

The shape of the osseous moulding of the inner ear, the organ of hearing and balance (represented here by a mouse deer ear, with landmarks that capture the shape). Inner ear shape was compared among a total of 40 mammals in the study by Grunstra et al. Sea cows, golden moles, tenrecs and tree hyraxes all belong to Afrotheria, a morphologically and ecologically very diverse group of mammals. The shape of the inner ear for a given afrotherian species is more similar to distantly related non-afrotherian mammals sharing the same environment (for example, sea cows and dolphins, which are both strictly aquatic) than to more closely related species (for example, sea cows and elephants).
