  • Why CC Hn>Hs>>He>>apith-ape?

    From littoral.homo@gmail.com@21:1/5 to All on Sun Nov 28 05:33:24 2021
    Why did Hn have larger cranial capacities than He?
    -more aquatic foods? incl. salmon??
    -more variable foods? incl.terrestrial?
    -more animal foods?
    -more variable food acquiring methods?
    -colder climate??
    -partly due to larger size?? Hn>He size?

    H.erectus was at least as aquatic as Hn was, possibly more:
    why were erectus brains "only" c 800 cc?
    -phylogenetic inertia: not enough evol.time?
    -diet: not only shellfish? more (aquatic) plant than animal food?
    -correlation with climate? less cold?? e.g. body size?

    If erectus ate also a lot of (aquatic?) plants, which exactly?

    Why exactly do many Odontoceti & Pinnipedia have rel.very large CC?
    -Sirenia? comparative data on different cetacean spp?
    -3D environment? less visibility? ...?
    -finding/grasping food? vs Mysticeti?
    -diet? animal food? seafood? DHA? ...?

    Ceterum censeo:
    only incredible imbeciles still believe their Pleistocene ancestors ran after antelopes.
