Specimen Data (Morphology)

At the distal end of the ulna, there is a swelling and outwardly rounded projection for attachment of the muscles used for flexing and adducting—hand motions that include spreading and folding up or bring together. This bony feature is the flexor carpi ulnaris tubercle. Primitive hand morphologies include long, robust, and curved fingers, and strong attachment of the flexor digitorum superficialis muscle. This muscle is located on the palm side of the forearm, and allows for flexing of the fingers. This combination of derived and primitive hand morphologies allows for precision grip, a characteristic exhibited in Homo, but not australopiths.
