  • hominoid/cercopithecoid differences

    From littoral.homo@gmail.com@21:1/5 to All on Tue Aug 23 12:34:14 2022
    Apes differ dratically from OWMs:
    - very wide pelvis, thorax, sternum:
    legs & arms more laterally than ventrally directed,
    scapulas dorsal rather than lateral,
    - much larger body (secondariy reduced in hylobatids),
    - centrally-placed spine:
    less lumbar vertebrae,
    more sacral vertebrae = sacralisation,
    less coccygal = external tail loss.

    Why?

    Continuum: from worm to fish to salamander to lizard to rat to lemur to monkey to ape to man.
