Im going to share some random facts about human biology you most likely did not heard of
1. Our feet
There are animals which are....
Plantigrades: always walk and run on their sole on the ground
Example: bears and most apes....
Digitigrades: walk on their toes with their feet elevated from the ground creating the impression of a "backwards pointing knee"... that is not their knee that is basically their heel and they stand only on their toes. They are generally very good jumpers and fast runners.
Example: dogs, most dinosaurs (birds included ofc)
Wel, humans are kinda plantigrades with a bit of both. We are supposed to wal
k long distances as a plantigrade because it is energy efficient in the long term but we are supposed to run or speed walk on our toes because it increases agility and speed at the cost of energy.
However most of us can't function good enough this way anymore because we
are forcing our feet into a small shoe and we lose some motoric functions along the way, i guess phenotypic plasticity causes some changes as our feet is adapting to our shoes when we grow (like, your toes might become curved from the lack of space etc)
Also, humans are absolutely among the top of the BEST endurance runners in the animal kingdom, behold the running savannah monkes! Our special ability is running (apart from our intelligence) , you can be fast but we will chase the fuck out of you til you get as tired you can't run anymore! (well most of you might not belive that because you can get tired easily etc. but it is also caused by the unnatural ways of life we are not supposed to live and most of us are weak bc of it)
2. We have oral problems like crooked teeth mostly because a diet we are not supposed to eat
What happens if you suddenly feed high energy processed foods to a monke which evolved for millions of years to eat tough chewy meat and vegetables without much starchy foods? Well the muscles used for chewing can't get strong enough, why is that a problem and how does it
affect teeth? The muscles used for chewing should very sloooowly pull apart your skull enlarging your teeth arch (with the help of your tongue) and remodeling your ramus so the wisdom teeth have enough space (because your skull is NOT a single bone, it is made up of many small bones at least when we are young)
Cavities are also caused by this bad diet, bacteria feed on starch and simple sugars then produce acids which basically dissolves our teeth, you wouldn't need 2 wash your teeth and you would still have healthy teeth if we ate what we are supposed to.
3. Humans are just animals
We are just apes, thats it, naked bipedal savannah monkes with the perfect abilities to exploit the whole environment.
I always go on the street looking at stuff like wtf dude we are so strange animals, mammalian termites or idk i mean other animals farm stuff too like fungi, plants, shrimp and build stuff from clay etc but we do all these at once.
+1 we have symbiotic relationship with our livestock and agriculture plants and pets
As in any symbiotic relationship the species affect eachothers evolution, domestic species basically specifically evolving to be more and more desirable for humans.
Lets look at some examples
Wheat and other plants and fungi: We get to eat some of the seeds in return we remove all of its competitors, nurture it and spread it
what kind of selection happens: the seeds become more and more nutritious over time as humans choose the largest, sweetest etc crops to pass on their genes
-some fishes farm algae, some ants farm fungi
Aquarium fishes: Looking at an aquarium causes us to calm down and mental health improves (scientifically proven) in return the fishes get a habitat free from predators
what kind of selection happens: humans choose the most beautiful specimens for breeding so over time they turn extremely colorful further estabilishing their presence as our symbiotic partners
-idk if any other animal does anything similar
Dogs, cats: they protect us from potential threats or catch things that we consider pests
today they mostly serve a similar way as aquarium fishes
-a species of tarantula spider keep and protect frogs as pets to deter pests
Livestock: Well.... that might seem strange but what is good for the species is not always good for the individual, yet it is still a symbiotic relationship as livestock species are the most
widespread animals in the world but like not all species livestock are eaten
-a species of fish farm shrimps to produce fertilizer for algae pastures
So, basically if you side with humans with a way or another you will be extremely succesfull.
If it goes on for a long time there wil be a lot of species adapted specifically for this relationship
+1 Why are there not much animals today as big as a "large dinosaur"?
It is called megafauna, and we fucking killed them.
You can be big, but that only protect you from brute power not from mind...
Studies show we always killed the largest, slowest animals first, then after they died out we went for the next largest, then the next... until only smaller faster breeding and harder to catch species were left.
The sloths larger than a T.rex, the mammoths, giant rhinos etc. and australia's strange giant reptilian fauna is all gone because of us... i miss the terrestrial crocs, the gigantics monitor lizards, the car sized tortoise-dragons, the giant birds wtf why we need 2 ruin everything
..uh did you know we actually killed off the largest turtle species ever to exist when humans colonized the amazon?
Anyways we are causing a relatively slow global extinction and decline in species diversity since humans are spreading around the planet, we are not entering the 6th mass extinction, we are already right in the middle of it, or is it the beginning of end game?
+1 Welcome to the Anthropocene
Here we are, it is not the holocene anymore, we caused so much change in the environment it will be detectable in the sediments. A layer filled with microplastic and increased radioactivity and decreased biodiversity will signal the beginning of the Anthropocene for the future paleontologists.
idk there was no science category so i published it in pets and animas as humans are animals
lol
im a fuckin biology nerd aint i
