    Tool use, or not tool use, that is the question: is
    the necessity hypothesis really inconsequential for
    the African great apes?


    (abstract)
    Investigating the drivers of tool use in animals
    has recently received great attention because of
    its implication in understanding animals’
    cognition and the evolution of tool use in
    hominins. The necessity hypothesis posits tool use
    as a necessary response to food scarcity, but its
    role is an ongoing debate. The largest body of
    literature comparing animal tool use frequencies
    is with regard to primates, particularly
    comparisons between the Pan species. This supports
    the hypothesis that tool use is rarer in wild
    bonobos because of differential manipulation
    abilities of chimpanzees rather than different
    ecological needs. In this article, I aim to enrich
    the discussion concerning the necessity hypothesis
    and the ecological drivers of tool use in apes. The
    higher feeding flexibility of bonobos may be a key
    aspect to explaining the lower use of feeding tools
    than that observed in chimpanzees. The diet
    flexibility of bonobos is similar to that of the
    lowest level of tool users among the wild great
    apes: the gorilla. Gorillas can thus help to shed
    further light on this debate. When fruit is scarce,
    Western gorillas and bonobos rely more on widely
    available proteinaceous herbs than chimpanzees,
    who remain highly frugivorous. Chimpanzees may
    thus face a greater necessity to search for an
    alternative to obtain high-quality food:
    tool-assisted feeding. An indirect piece of
    evidence for this higher level of herbivory is that
    the prevalence of gut ciliates in bonobos is double
    that of chimpanzees. In each animal species, a
    different combination of necessity, opportunities,
    predisposition, and learning processes are likely
    to be at play in the emergence of flexible tool
    use in animals.

    This is idiocy. When this jackwads can't differentiate hominins
    from birds or even invertebrates, as their misuse of "tools"
    would apply to all, what is even the point?

    The way they define "Tool use," it's unknown and unknowable.

    MONKEYS USE TOOLS, going by the idiotic way this jackwads
    define it. NEW WORLD MONKEYS!

    So we're talking, what? Only 35,000,000 years of New World
    Monkeys and... oops! They were already diversifying by then!

    They'd been around longer, for sure...

    So their "tool use" probably goes back at least that far, if the
    way they misuse "tools" is applied consistently and..

    Oops. Invertebrate, at least some of them, qualify as "tool
    users" under their idiocy. So why not the Cambrian Explosion?

    The point here, because idiots need it spelled out for them, the
    stupid way they misuse "Tools" guarantees we can only "study"
    the merest fraction of even the recent history of these so called
    "Tools." We have a mega fragmentary sampling from less than
    1% of the history of probable tool use, a lot less, and you want to
    pretend we can work out it's evolution?

    Can any of these morons even breath through their noses without
    tripping?

    Only prejudiced savanna believers still use "hominin": in PA literature, this word presupposes that australopiths were closer relatives of us than of Pan or Gorilla - which is obviously wrong. When I read an article that uses the word "hominin", I know:
    it's written by some fool who believes we became "bipedal" when we left the African forest (Miocene Hominoidea were already bipedal, of course, google "aquarboreal").

    This is idiocy. When this jackwads can't differentiate hominins
    from birds or even invertebrates, as their misuse of "tools"

    Yes, sea-otters are *the* stone tool users.

    They are & some will remain morons.

    IOW, empty blabla...

    Stone tools = sea-otter = opening shellfish:

    H.erectus = molluscivore:
    • tooth-wear was caused by "sand & oral processing of marine mollusks", Towle cs 2022 https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24500
    • fossilized in coastal sediments, e.g. Mojokerto: barnacles + corals, Trinil: Pseudodon + Elongaria (edible shellfish), Sangiran-17: "brackish marsh near the coast".
    • made sea-shell engravings, google "Munro Joordens" https://pubmed.ncbi.nlm.nih.gov/25470048/
    • ear exostoses (H.erectus & H.neand.) = years of cold(er) water irrigation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696936/
    • pachy-osteo-sclerosis = slow+shallow-diving tetrapods (de Buffrénil cs 2010 J.Mamm.Evol.17:101-120), e.g. erectus’ parietal bone is 2x as thick as in gorillas.
    • brain size (2x apes/australopiths) = aquatic foods, e.g. DHA docosahexaenoic acid in shellfish… cf. Odontocetes, Pinnipedia.
    • island colonizations: Flores, Luzon... https://www.academia.edu/36193382/Coastal_Dispersal_of_Pleistocene_Homo_2018
    • stone tool use & dexterity = molluscivory, e.g. sea-otters.

    Only *incredible* imbeciles still believe they descend from antelope hunters... :-DDD

    Do dolphins use tools?

    If you had reading comprehension you would know that you
    already received an answer.

    This is not primary school and I am not your teacher. And
    neither am I your therapist.

    Yes, these idiots think dolphins are sea-otters... :-D

    Nobody doubts early-Pleist.H.erectus in SE.Asia were predom. molluscivores:

    Nothing has changed. This still isn't primary school, I'm still

    You're applying the word "Tools" to behaviors, not object, and
    you're such a basket case that you are emotionally incapable
    of dealing with this fact.

    And that's funny.
