Oikeakätisillä

Oikeakätisillä refers to individuals who are predominantly right-handed. This handedness describes the tendency to favor one hand over the other for fine motor tasks such as writing, throwing, or using tools. The vast majority of the human population exhibits right-handedness, estimated to be around 85-90%. While the exact causes of handedness are complex and not fully understood, it is believed to be influenced by a combination of genetic and environmental factors. Research suggests that brain lateralization, where certain cognitive functions are localized to specific hemispheres, plays a significant role. The left hemisphere of the brain is typically dominant for language and fine motor control in most right-handed individuals, and it controls the right side of the body. Cultural and societal factors have historically influenced how handedness is perceived and accommodated, though modern societies are generally more inclusive of both right- and left-handed individuals. The prevalence of right-handedness has been relatively stable throughout human history, as evidenced by archaeological findings.
