You're speaking on the phone, holding it in your left hand, looking at the watch on your right, one sipping from a coffee cup in your third hand and opening your laptop to turn on a new bright side video with your fourth hand. How's that for convenience? What you see fish began to crawl onto the land about 500 million years ago. It had four fins that started to turn into a limbs during evolution. This way, amphibians could move through the mud. The further these amphibians went, the more their fins look like legs. Some animals began to climb with their hind limbs after several 100 million years, and the rest is history. But what if evolution had changed its course a little? If the fish had six fins and the amphibians had six limbs? Creepy but fascinating. Okay, I know you're itching to find out, so let's look at us humans in this scenario, starting with birth, always a good place to begin. It's the eighth week of your stay inside your mother's womb. Your two legs and four arms begin to form. During this period. Your body needs more nutrients because of the additional two limbs, which means that your mother consumes much more food during pregnancy than an ordinary pregnant woman You were born and all four of your little hands immediately grasp your mom's hand, the first to grow from the shoulders. The other two are just below the ribs. You, my friend, are Quad Menace, meaning four handed childhood. You have twice as many toys as an ordinary kid. When your mom tries to put you to bed, she cradles you in her arms, feed you from a bottle and rattles a toy in front of your eyes all at the same time. Parents change your diapers twice as fast who, while two hands take off your dirty diaper, the other to prepare a clean one. The kitchen turns into chaos during lunch, your scattering food in four directions, tapping with a spoon on the table. But parents are coping. Mom wipes the stained table with one hand, feed you with the other. She pours tea with 1/3 and fries the omelet on the stove with the fourth your parents by a dog, so that you are not so aboard and the dog has six legs instead of four because the dogs distant ancestors also crawled out of the water. With six limbs, you grow up and start going to school. The desk you're sitting at is slightly larger than regular desks. The teacher writes math equations on the white board with both right hands. You rewrite them in a notebook with one hand, make a paper airplane with your second and third hands and throw a crumpled sheet of paper on your classmate with the fourth parents. Enroll you in a drawing club. Art has become or funny in this world. People with paintings by Leonardo da Vinci, Rembrandt sculptures by Michelangelo all have six limbs. Not only the image of a person changes in art, but the drawing process itself. Canvases are wider. The picture is more detailed, the colors are brighter. But drawing doesn't attract you so much as sports does. You start attending a sports club. It's double basketball. There are two balls instead of one. Players dribble with both at once and throw them in the double basket. Sport altogether is very different from what we're used to. Fencing with two swords, boxing with four gloves, which makes fights even more spectacular in tennis athletes Mac two balls using four rackets. Pull votes are twice as high because of enhanced push. Break dance looks even cooler. A gymnast performed tricks like Spider Man. Anyone, even a person far from sports is a good climber. Runners have increased running speed. The scope and movement of the hands make them faster. Also, people's legs have become stronger and more resilient because of additional weight in the body. People swim much faster to now. You can cross a lake twice as fast in a boat without a motor. Just take four yours and you love winter playing snowballs in particular, you launched two snowballs at once, and your opponent has no chance of dodging youth. You become a star of double basketball. You score two balls at once in two baskets and make your team the winner in the school championship finals. Your friends hug you tightly. The forearm hugs are pretty strong, but you're back is stronger. You go to the shower and spend mawr shower gel after training. The deodorant is used for four armpits, and it depletes faster. You're a teenager and have begun to devote more time to your appearance. You dress in fashion stores where all outfits have force leaves. The fashion world has changed a lot in this world altogether, there's twice as much jewelry to be worn manicures to be done and watches to boast with backpacks and bags have four straps. People wearing expensive fur coats resemble huge spiders. Well, you pick up twice as many goods at the grocery store, but not only because you can carry four full bags, but also because you need more food to extra arms and hands need extra calories. Humanity has begun to consume more, but the earth's resource is remain the same. So food and water, arm or expensive. Here you finish school and go to college. Majoring in biology, you study hard record lectures and type a lot on the computer. Your print speed is twice as fast. Forehands means multi tasking, so computers have to mice and expanded keyboard with additional features. Phone screens have become whiter. You can chat with four hands at once. You attend music concerts in your free time. Two piano keyboards instead of one, twice as many strings on a guitar. When drummer is completely surrounded by drums and can produce amazing beats solo rhythm, dynamics, speed. Everything has improved in music. Superstar Seymour raised hands at their concerts, but fitness trainer spend much more time and gyms. Four muscular arms are harder to get them to. Restaurants work at a hectic pace. Waiters deliver four trays at a time. Cooks can cook two dishes at once. We even eat faster with two forks and knives. One of the most sought after professions is a massage therapist. Forehands need and massage the muscles at the same time. The increased speed and multitasking in many aspects of life have made people more advanced. In technology. Medicine treats almost all diseases. People have learned to create artificial organic food on a large scale. Then there's adulthood. You've successfully graduated and now work as a biologist at a research institute there. Ah, you meet your future spouse. You bend your knee before them to make a wedding proposal and show two rings. They agree. At work, you study the reasons why evolution has decided to reward all animals. With six limbs, you fly to the Amazon rain forest to explore the local fauna. Animals there move on six legs. This makes them faster, stronger and more agile. Here you discover an unknown species of primates with only two arms and two legs. Thanks to the advanced DNA analysis, you find out that the ancestors of these primates came out of the water Ah, 100 million years earlier than the rest of the fish. They crawled out toe land and developed four limbs. All other amphibians swam in shallower waters for millions of years more and grew to extra fins so that they could escape from predators faster. I wonder what the world would be like if people had only four limbs. You think after completing your research Bottom line. Yeah, this is all interesting. I'm pretty sure that shirts, jackets, coats and the like will be more expensive. With all the extra sleeves, magicians will be able to impress us more, since they have more sleeves to hide their tricks. Playing poker with four hands means you'll win or lose twice as fast, and you'll get your ice cream faster in the malt shop where the soda jerk has four arms to dish out the desserts and vast the scoop. Hey, raise your hands. If you learn something new today, what Onley too? Well, then give the video alike and share with a friend and hear some other cool videos I think you'll enjoy.
