  • Human evolution is not so difficult

    From [email protected]@21:1/5 to All on Fri Mar 11 03:22:29 2022
    Human evolution is “special” but completely conform all biological rules. H.erectus had pachyosteosclerosis POS (pachy=thick, osteo=bone, sclerosis=dense): such very heavy skeletons are uniquely seen in slow+shallow-diving tetrapods in salt water,
    IOW, there’s 0 doubt that erectus on their dispersal as far as Java (e.g. Trinil) & later Flores island etc. followed the sea-coasts (& from there often inland along rivers?). Shelfish consumption explains a lot: erectus’ drastic bain enlargement (
    DHA & other brain-specific nutrients) cf. seals & dolphins, the shell engravings Stephen Munro found in Debois’ collection (google “Joordens Munro”), Homo’s stone tool use & dexterity, fossilizations in coastal plains, etc.etc. It’s
    astonishing that some paleo-anthropological handbooks still assume that we evolved on African savannas, e.g. running after antelopes (e.g. endurance-running!): this is the most unscientific fantasy imaginable! Google “coastal dispersal Pleistocene
    Homo PPT”.

    I rewrite it a bit:

    Human evolution might perhaps be called “special”, yet it is perfectly in accordance with all biological rules.
    H.erectus typically had pachy-osteo-sclerosis or POS (pachy- thick, -osteo- bone, -sclerosis dense): a very heavy skeleton, with very thick & dense cranial & postcranial bones.
    POS is only seen in slow+shallow diving tetrapods in salt water, apparently for facilitating diving, IOW, erectus & their relatives on their intercontinental dispersal (e.g.Trinil, Flores...) simply followed the seacoasts (and from the coasts repeatedly
    the rivers inland?).
    Shellfish consumption iexplains a lot of unexpected facts we know of archaic Homo: their drastic brain enlargement (cf. dolphins & seals, DHA in shellfish), the shell engravings found by Stephen Munro in Eugène Dubois’ collection (google “Joordens
    Munro”), Homo’s stone tool use, the fossilizations of erectus in coastal plains, etc.
    It is astonishing & incomprehensible that there are still PA handbooks that assume (with 0 evidence) that early-Pleistocene Homo became runners on African savannas: the so-called endurance-running idea is the most unscientific fantasy imaginable!
    For a realistic (biological) view on Homo’s evolution, google “coastal dispersal Pleistocene Homo PPT”.
