In my mind, consciousness is pretty much just a manifestation of multiple pieces of information and brain processing coming together. I don't think it exist in any physical way, it is more like an experience.
My biggest question is can your ancestors memory be passed down. Like animals do things that they shouldn't even know to do but it's basically built into their Brain to do that? Again novice here lol
So one could suggest consciousness is the soul. It exists because your consciousness makes it exist and it can’t exist without itself. A kind of mental paradox.
The appendix I have heard is kind of a refuge for microbes that helps us restore our microbiome after something like an infection or food poisoning. I have heard that people who have it removed tend to have more digestive tract issues and take longer to recover, although I have no idea if any of this is true in any way.
Remember the guy who had a concussion, woke up and was able to play the piano with precision and skill even though he had never touched a piano before?
its a difference of having an idea what those functions do and beeing able to proof it. Its called a theory obviously, but proofing one can be much more complicated,
In the case of the appendix; studies have shown that after a "cleansing of the gut" (diarrhea) bacteria levels return to normal faster in people who have their appendix, so it's like it keeps an emergency supply of your gut bacteria which is kinda cool.
Actually the chimp claim is slightly exaggearted. Humans arent that much weaker than chimps. Infact, that study compares chimps and humans of the same size. Since humans are bigger than chimps a bigger human could out perform a chimp in absolute terms. But yes, your statment about endurance is true. Upright walking is much more energy costly than all fours for animals like chimps. Our smaller muscles help mitigate that
We also have counter-nerves to prevent our bodies from ripping itself apart. We are stronger than you think. This goes hand in hand with the endurance thing.
I’m pretty sure sleeping has been proven to be to allow the brain to drop motor functions and functions like sight, smell and touch to work on internal things. Healing, growth, digestion, quarantining sickness etc.
Sleeping allows us to store information and allows our brain to focus on other things other than being conscious. This is why the brain is more active at night. Another reason is our muscles regenerate after exercise and I'd say 98% of the time the regeneration is done in our sleep, it allows the brain the address the various issues that could be dangerous to our survival and therefore fix them while it doesn't have a conflict with consciousness. Edit: Not proven but I believe that dreams access information that we learned throughout the day or helps you, yourself, address an issue that only a conscious mind can help such as trying to build up confidence and such. Dreams to me are like a debriefing before entering the conscious state.
Honestly I think that the human brain is so complicated that I can't even begin to understand it. There have been cases where people have had concussions and woke up speaking new languages perfectly when they had no ties to the countries that speak said languages.
The brain is always recording information unconsciously, you could flick through TV channels and hear a few words in french- your brain will store that information unconsciously however you yourself won’t understand it because you think with a conscious mind
I like the theory that yawning was to communicate to the group that it’s ok to sleep, it makes sense for us as social creatures to have traveled in large groups, and with no (official or found) way to communicate during these times with words, yawning is a good indication and can be a reasonable theory as why it’s contagious to me. Edit: we’re also closely related to bonobos not just genetically but also mentally when it comes to altruism, if you want a source I recommend reading Bonobo and the Athiest. It’s a great book I read during my primate behavior course in college.
Sleep can be related to why we charge our cell-phones. My guess is that it regulates the neurons inside our brains so that we may have greater ease sending our electrical signals to our nerves to move. Dreaming may help us to disperse with the saved mental imagery, which of course we no longer need. These are just my crazy thoughts...

It's actually theorized that the appendix is to protect bacteria that is good for your body before the bad bacteria comes through. I don't recall the exact article I read this in...
There's the theory that our body hair is on it's way out or at now the maximum it'll be again. Hairs are excellent sensory organs, it can be easy to tell when a pest has landed on you. It's small enough to land on the hair but not touch the skin, so feeling a hair move is uncomfortable and you want to scratch or smack at it to push the pest away or off of you. One other theory that's not mutually exclusive is that humans started shedding body hair because it provided shelter for detrimental creatures like ticks and lice. Now there's usually only two areas that get infected with lice.
When I was around 12 I think I broke my right wrist but because I wasn't in any sports I had to learn how to use my left hand or fail every class I had so I was right handed and now I can use both lol

Many of these things are overly simplified and maybe don't need a complex explanation. Fact is we have natural reactions to much of these and that can be an answer.
I remember being told in school that yawning was due to lack of oxygen, which semi made sense for it being contagious. If i saw someone yawn, not only would it tell me that there isnt much oxygen in the air, but some guy is stealing the last of it
Dreams are in my experience essentially just sensual manifestations of stuff I happen to think about while asleep, with both conscious and unconscious thoughts feeding off of each other back and fourth. Sleep also is pretty important for lerning, especially long term stuff so I think it might be a possibility that we do it because of all the neural connections that are being made, strenghtened and changed. If we were awake during all of this it we'd probably have constant seizures, delusions, halluzinations etc. I can see that kind of looking like schizophrenia although that'd require a link between that and sleep I do not know of any.
I often wondered if yawning is a exercise for the jaws and mouth and helps them relax/change position? (in addition to the theories about the brain mentioned).
Eye color is believed (from what I understand not going to say for certain) to relate to our personality. Darker eyes are supposed to be more aggressive and less sensitive to light. Blue, grey/silver and other light colors are supposed to be more calm, belong to people who are more intelligent and are more sensitive to light.
0:05 "why do we yawn?" I kinda wish they covered this in Biology class, but instead we got boring stuff about cells and cytoplasms that just made you yawn
You can also live without a gallbladder. But since it regulates and moves fat and grease, you , well me, have to be a little more careful about what you eat. You, (i) can get nauseous at times.
we do know why we have a dominant hand. many mammal species show a preferred hand for activities. the best explanation is that it only makes sense to put energy into developing one-handed skills e.g. writing in one hand than divide that energy into two hands.
The reason you yawn is to regulate breathing, if you aren't getting enough (such as when you are tired), or are getting to much Oxygen, it regulates your breathing. If this is incorrect, blame my band teacher.
Yawning is the body's way of adapting to a change in your breathing speed, when you breathe slower than you previously were, you yawn so you can take in extra oxygen to adapt to that change. Same thing for if you breathe faster than you previously were, try it.
Each of us is a world to the trillions of tiny creatures that share our personal space, inside and out. We give them safe harbor and nourishment, and in return, they can help keep ill creatures at bay and even assist us in getting more nutrition from things we can't digest well with our own facilities. The microbiome is a complex and often surprising part of our lives -- I look forwards to learning more about it, as new research comes in.
There may be a connection between people who are dyslexic and also left handed. I don't know if there's been a study about it, but there should be. I would love to know if everyone who has dyslexia is also left handed...
Sometimes people yawn because they need more oxygen. Idk how to explain it but I deeply yawn (can feel it in my chest) when I refuse to use my inhaler. I keep yawning until I use it and start breathing correctly
Wasn't the appendix meant for breaking down certain meats before we started cooking food and overtime, with the lack of eating raw meat, the appendix shrunk? That's what I was told
Most sharks sleep with one eye open because if they stop swimming, they die. Also, some birds do it too, they even sleep on the the wing. Something about only half their brain sleeps at the time
Actually, chimps are so stronger then us because our muscles have more nerves to complex jobs then to contract their fiber all at the same time, witch would give more strength. Chimps can contract much more muscle fibers at the same time in each muscle, we can contract different fiber groups in complex paterns. That is why we have muscles so similar in anatomically so similar, but functionally so different.
As far as I know the Ancestors of humans evolved in africa or other regions that tend to get really hot. I can see it making sense if they lost their fur in response to evolving sweating as a primary method to cool off. Fur may have interfered with the heat transfer or evaporation of sweat. The reason we kept hair on our head was probably to protect our head from direct exposure of sunlight since that can cause a lot of problems after a while.
I remember back in school, my professor told us that yawning was meant to keep us alert. This is why other animals also yawn.
