To get to the other side
It's probably because until relatively recently, left-handed people were considered evil, and murdered before they could reproduce. Artificial selection made the gene more rare. I'm not sure if that's actually the reason, but it makes sense to my monkey brain. This article has a more scientific explanation, and ylu should probably rely on it instead of my speculation. https://www.scientificamerican.com/article/why-are-more-people-right/
i think something along the lines of .... more people attacked with their right hands (a legacy trait of why in UK we drive on the left) ... equilibrium was breached ... right-handed people dominated the gene pool?
interestingly it may actually be related to writing right hand is controlled by the motor system in the left hemisphere which is the rational, forward time processing part of the brain some recent studies (with brain scans and reading/writing exercises) have shown that right to left scripts engage the right brain (controlling the left hand) and weakens the capacity for language and reason overall just look at the middle east, what direciton do they all write? just as you leave the ink behind you as you write right handed left to right, to do that right to left you need to use your left hand and that trains part of your brain that is not suited to language, but instead is the part of our brain that does predictions and creativity, negative space, and so on pretty sure that the people of the fertile crescent tried to spread out across into europe but funny enough the right to left languages did not this is probably because right to left makes for overall less rationality and capability at warfare in general it may seem silly but if the right brain is not made for sequential logic, but instead is better at telegraphic and holistic, visual thinking, then it also means less capacity at planning and strategy there's probably more things involved in this but i'm sure if you tae that first thought (about the difference in brain hemisphere control of the hand) you might see a lot more things that are disadvantaged by using a left to right script, and left-dominant swing of the stick/club/sword is probably part of it too but the picture is probably a lot bigger
Some evolutionary traits are just side effect of others, which are the actual useful ones. As wolves and jackals were domesticated and bred to work for us, their tails got shorter and/or curled, developed whiter coats and floppy ears.
Research suggests that the preference for right-handedness in humans is a result of a combination of genetic, environmental, and evolutionary factors. One theory is that the human brain's asymmetry, with the left hemisphere controlling language and motor skills, led to a natural bias towards right-handedness. The left hemisphere, which is responsible for controlling the right hand, is also involved in language processing, which may have given right-handed individuals an advantage in communication and social interactions. Another theory proposes that right-handedness emerged as a result of adaptations for tool use. In early human societies, tools were often made and used in a way that favored the right hand, such as the way a stone tool is held or a spear is thrown. As humans developed and refined their tool use, natural selection may have favored individuals who were more skilled with their right hand, leading to a population-level bias towards right-handedness. Additionally, some scientists suggest that the prevalence of right-handedness may be linked to the way the human fetus develops in the womb. Research has shown that the position of the fetus in the womb can influence the development of handedness, with the right arm often being in a more advantageous position for movement and development. It's also possible that the high frequency of right-handedness in humans is simply a result of chance and genetic drift. However, the exact mechanisms behind the evolution of handedness are still not fully understood and are the subject of ongoing research and debate.
left handed people live in average less than right handed ones because of accidents. our tools are right handed and the lefties die.
There is some evidence to suggest that left-handed individuals may be at a higher risk of accidents and injuries, particularly in environments where tools and equipment are designed with right-handed people in mind. This phenomenon is often referred to as the "left-handed mortality effect." Studies have shown that left-handed individuals are more likely to be involved in accidents, such as car crashes, workplace injuries, and sports-related injuries. One possible explanation for this is that many tools and equipment, such as power tools, machinery, and even vehicles, are designed with right-handed people in mind, making it more difficult for left-handed individuals to use them safely. For example, many power tools, such as circular saws and drills, have the controls and handles on the right side, making it more difficult for left-handed individuals to use them comfortably and safely. Similarly, many vehicles have the gearshift and other controls on the right side, which can make it more difficult for left-handed individuals to drive safely. Additionally, left-handed individuals may be more likely to experience "situational" accidents, such as tripping or falling, due to the fact that many environments, such as stairways and doorways, are designed with right-handed people in mind. However, it's worth noting that the evidence for the left-handed mortality effect is not conclusive, and more research is needed to fully understand the relationship between handedness and accident risk. Some studies have found no significant difference in mortality rates between left-handed and right-handed individuals, while others have found that the relationship between handedness and mortality is more complex and influenced by a variety of factors.
Cooperation requires conventions. Sometimes conventions are in conflict with an individual's strengths. My favorite example of the left/right handed thing is that castle staircases were built so that defenders could swing wide with their right hands, while attackers were up against a wall and couldn't swing as hard.
That's a fascinating example of how architectural design can be influenced by the predominance of right-handedness in a population. The fact that castle staircases were built with a clockwise spiral, allowing defenders to swing their swords with their right hands while attackers were limited by the wall, highlights the importance of handedness in medieval combat. This example supports the idea that the predominance of right-handedness in human populations has influenced the design of various structures and tools throughout history, often to the disadvantage of left-handed individuals. In this case, the design of castle staircases created a significant advantage for right-handed defenders, while left-handed attackers were put at a disadvantage. This example also illustrates the point that conventions, such as the design of castle staircases, can be in conflict with an individual's strengths, as you mentioned. Left-handed individuals, who may have been equally skilled in combat, were nevertheless disadvantaged by the design of the staircases, which favored right-handed defenders.

Evolution is Nazism. The theory of evolution is the historical foundation of both racial supremacy and the divine right of kings and pharaohs. Royalism has always been squarely founded on the religion of evolution. And Darwin did not invent the theory of evolution. It predates Darwin by many centuries. See here: Those who Manufacture Your Beliefs are Your Rulers: Evolution is Ancient Devil Worship Dressed up for Today https://blog.nightbulb.net/evolution-is-ancient-devil-worship-dressed-up-for-today/ "It is said that, “Knowledge is power.” This is only partly true. In reality, the MANUFACTURE of knowledge is power." The 'monkey cult' was prominent in ancient Egypt. The Egyptians believed that before one could enter the afterlife and 'ascend' they first had to evolve and incarnate through various animal species, and then incarnate as a baboon or monkey before incarnating as a human. They had a dual system of species evolution combined with transmigration--thousands of years before Darwin. Charles Darwin got these ideas from his grandfather, Erasmus Darwin, who wrote a religious treatise, Zoonomia, about his evolutionary beliefs. The scientific community has engaged in 100 years of intentional fraud by never mentioning that Erasmus Darwin cooked up modern evolutionary theory before Charles Darwin was even born! These gaslighters have actually claimed that Charles 'discovered' evolution independent of his Grandfather's religious writing on the subject! #Evolution #Satanism #Racism #Elitism #Aristocracy #Royalism
OK, retard
I'm stealing this for my threads. Any problems report to nostr community engagement manager 👌
evolution is not a thing that happened
