    Scarier than lions. I bet that's been imprinted on these animals at
    least since Homo erectus.

    Computer simulation of scavenging by hominins and
    giant hyenas in the late Early Pleistocene

    Abstract
    Consumption of animal-sourced food is an important
    factor in broadening the diet of early hominins,
    promoting brain and body growth, and increasing
    behavioural complexity. However, whether early
    hominins obtained animal food by scavenging or
    hunting large mammals remains debated. Sabre-toothed
    felids have been proposed to facilitate the
    expansion of early Homo out of Africa into Europe
    1.4–0.8 Ma by creating a niche for scavengers in
    Eurasia as the carcasses abandoned by these felids
    still contained abundant edible resources. In
    contrast, it has been argued that the niche for a
    large scavenger was already occupied in Eurasia by
    the giant hyena, preventing hominins from utilising
    this resource. This study shows that sabre-toothed
    felids generated carcasses rich in edible resources
    and that hominins were capable of competing with
    giant hyenas for this resource. The simulation
    experiments showed that maintaining an optimum group
    size is essential for the success of the hominin
    scavenging strategy. Early hominins could outcompete
    giant hyenas only if they could successfully dispute
    carcasses with them. Thus, in the presence of a
    strong competitor, passive scavenging is
    essentially the same as confrontational scavenging.

    Notice that in one of the video's even the leopard drops its prey and
    runs when it hears a human voice. That's a free meal!

    Of course, if you happen to be near by. Hyenas follow leopards all the
    time, so when leopard eats, one hyena calls for the other, and those two
    hyenas steal the prey from leopard. This is how hyenas feed. Humans
    cannot follow leopard (if for no other reason, humans get hungry
    sooner). Especially not a bunch of humans. In the above example we have
    two hyenas eating. For a bunch of humans you need more food.
    Also, there is a sound that is scary for humans, a sound produced by
    tiny animal:

    But, you will not understand any of it, anyway.

    That's why they're so smart...

    H.erectus were originally predom.molluscivores, my little boys:
    • Archaic Homo's atypical tooth-wear was caused by "sand & oral processing of marine mollusks", Towle cs 2022 https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24500
    • H.erectus s.s. typically fossilized in coastal sediments, e.g. Mojokerto: barnacles + corals, Trinil: Pseudodon + Elongaria (edible shellfish), Sangiran-17: "brackish marsh near the coast".
    • Stephen Munro discovered sea-shell engravings made by H.erectus, Joordens cs 2015 Nature 518:228–231 https://pubmed.ncbi.nlm.nih.gov/25470048/
    • Ear exostoses (H.erectus & H.neand.) develop after years of cold(er) water irrigation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696936/
    • Pachy-osteo-sclerosis is only seen in 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 in erectus (2x apes=apiths) is facilitated by aquatic foods, e.g. DHA docosahexaenoic acid in shellfish… cf. Odontocetes, Pinnipedia.
    • Late-Pleistocene descendants or relatives colonized Flores 100–50 ka & Luzon 67 ka https://www.academia.edu/36193382/Coastal_Dispersal_of_Pleistocene_Homo_2018
    • Homo’s stone tool use & dexterity is typical for molluscivores, e.g. sea-otters.
    Etc.etc.
    Perhaps your ancestors scavenged, but not mine. :-DDD

    Yes, see bees & other insects with minuscule brains, flying (muscle control), finding+collecting foods, making nests, procreating etc.

    I believe I took this idea from somewhere. I said this just to emphasize that size doesn't matter that much, as scientists usually
    think. The size of brain, I meant, :) . In general, I don't
    underestimate animals. And definitely I don't overestimate humans. I
    consider humans being just an regular animal. I really don't see where
    from any irregularity would come, and, as far as I know, nobody ever
    pointed to anything specific, or the reason why would this apply
    specifically to humans. We are just an animal which has 10 fingers and
    the ability for vocal communication, which we developed for, probably,
    10 my (if not even longer). Also, there could be a point when vocal communication could expand exponentially, if you achieve certain level
    of it. Why not? When vocal communication is rude, it develops slowly,
    after all, it is based only on limited abilities, but, after some time
    those abilities expand, and then it can develop enormously, it is just
    the nature of the beast. When you start to play guitar you can only play
    "Smoke on the water", but once you achieve certain level suddenly you
    can play anything (I presume, I am still on the "Smoke on the water"
    level, :) ).
