    Good video! Yet another explanation is given by Professor Lia Amaral. She measured the weights of young primates of different species when they become autonomous and the resistance of the hair of the respective mothers to conclude that the need of carrying the babies by humans (instead of them hanging) was an evolutive drive towards bipedalism.

    notes for pp to better study :
    provisioning model:
    (owen lovejoy) main adaption for pair bonding:
    1. males no longer fight for females
    2. males carry food by walking upright& females look after the young
    3. evidence: the size reduction of the male’s canine teeth and body size compared to the female
    energy saving:
    1. environment changes=>food dispersed=>move further for food
    2. chimpanzees bipedal and quadrupedal : human walking= 1 : 0.25
    =>shift to bipedalism aint difficult& support provisioning theory
    savannah hypothesis
    not supportive:
    1. evidence=>bipedalism developed in trees
    2. Lucy was shorter than modern humans=>not looking for predators
    postural feeding hypothesis:
    1.gathering hard-to-reach food=>explains partially bipedal
    thermo-regulatory model:
    1. reduces surface of body to sun and hot ground
    2. gets winds to keep cool
    humans and apes:
    1. human thigh bone is both longer and angles inwards: stand for long periods
    2. pelvis& s-shaped spine: balance
    now humans suffer:
    1. back problems
    2. women’s wider pelvis=>hurt knee joints

    The problems you point out directly contradict why humans should be walking upright today. If walking upright causes back pain, would our evolutionary process try to eliminate this negative trait? Why would walking upright eventually lead to back pain become the dominate trait over time... that does not make any sense at all.

    • @octoling6479
      @octoling6479 3 роки тому +1

      That’s because everything has it’s pros and cons. Yes we became bipedal, which allowed us to free our hands and use them to tools, but due to the shape of our spine, it caused us to have back pain. Yet the s shaped spine does work on supporting up right movement. The point is evolution doesn’t attempt to make things better, it just modifies already existing traits to make them work.

    If the sole reason or dominant reason to become bipedal was to reach the apples on the top of the tree then why not remain tree habitant and never come to the ground in the first place? Not very smart move to first land on the ground and then try to pluck the apples from there which were within arms length when tree dwelling. I think the real reason is the urge to do slow dance and the square dance in ballrooms.

    I much prefer the "aquatic ape" hypothesis, elaborated and expanded by Elaine Morgan, which suggests that during the increasing climate change which drove our ancestors out of the shrinking forests, they followed rivers to beaches / coast lines so as to escape the main heat and most familiar predators and to find easier food that didn't need to be hunted, like shellfish or beached seals. There's sea caves, vegetation near estuaries and most importantly, any predators like sabre toothed cats cannot follow them into the sea. The whole point of being bipedal, initially, was to stand in the sea covered beach so that nothing can hunt them - felines can't win a fight with them, it's too shallow for sharks. crabs and seals aren't going to hurt them, and the worst they have to deal with is the cold, pebbly beaches and maybe floods.
    They might have stayed there until the climate levelled out, and their new adaptions, like stronger and taller legs, or less reliance on trees and fruit, and more on caves and meat, brought them to the Savannah.

    • @Philip-1
      @Philip-1 Рік тому

      Of course, crocodiles would be a concern, but I still agree with most of the aquatic ape hypothesis. I'd also mention the importance to brain development of fatty acids found in fish.
      Shallow water food sources are much more resistant to environmental changes, like long winters or droughts, than land vegetation.

  • @sleepsmartsmashstress740
    @sleepsmartsmashstress740 3 роки тому

    Energy conservation by using one ambulatory technique instead of a similar one conflicts with physic in terms of law of conservation of energy. To move a specified mass of body by the same distance by any means should require the same amount of work and same energy expenditure. That humans consume 75% of energy than chimps for the same weight and distance poses a problem that requires reconciliation. Were bidedal ambulation superior then humans should be able to outrun cheetah and several other large canines who are much faster than humans. Bipedal walking is pretty clumsy and is compared with walking on stilts but running is bit better but still humans are very slow runners.

    Overly simplistic. Bipedalism requires major design changes . The balance mechanism in the ears has to readapt for upright locomotion, the hip, legs, knees and feet have to change radically. Also the spine and positioning of the head vertically above the spine is needed. All these changes have to take place in harmony with each other. This is a design problem........ mindless evolution cannot account for this.

      the shift to bipedalism in humans is a prime example of how evolutionary processes can lead to complex adaptations over time without the need for a "designer." The fossil record, the interconnected nature of anatomical changes, and the principles of natural selection all provide robust explanations for this significant evolutionary transition.

    i found a Australopithecus skull it was white crystalline quartz at crook well Brook lands cnr of tait and john st on the side of the road a peasant village or rural area. one day 2009-2010 . i kept it as a prop for my lounge as i had no idea what is was i thought i was just a rock. later three moths when i did the proper clean under the lounge and stuff. i place it on my table , i had finished cleaning and was sitting down for a coffee when i looked at it and i could see the eye socket half of it was perfect the other half was pushed , however there was enough after inspection to see perfectly formed teeth in white crystalline quartz the back bone section the clavicle, the nose the ear and even proportion. it was an amazing find. i id not even know how old it was or was anyone around me who seem to have any real skills in this matter more ball and bat people , farmers.
    however there were two things that even to today freak me out as i looked at it under the magnifying glass and good light at night i could see a clear outline to what looked like a small spear like shape defined exactly on the surface of the skull a small pencil length spear with a point to a wider angle a hand held wooden device. but how old was this i mean crystalline quartz takes millions of years to form one such a large piece .20 cm of white crystalline quartz at one centimetre a million years is 20 million but i was thinking more 3-4 million but i am no expert. i looked at the skull for hours scanning everything around it , i did not believe it when i could see a tiny shape that looked like a small horse. on the skull however the front section to the horse was different more of a shorted mouth but definitely a small horse. it would of only been maximum 10 cm tall .
    ok so why did we stand up that is what i wanted to say. our species or the overall reason.
    well it was in anger actually , the first time that we ever stood up was a group of four creatures three males and one female, one male protected the female against the other two males and he stood up and roared at them protecting his mate, this was the first time our species ever stood up and after that everyone was impressed.as our species never knew it could do that .
