In this blog we will learn the secrets behind what makes us right or left-handed. From biological factors to environmental influences.
Research suggests a genetic component to hand dominance, with studies indicating that handedness can run in families.
The brain’s hemispheres play a vital role in hand dominance. The left hemisphere is typically associated with language and fine motor control.
Hormonal influences during prenatal development may contribute to hand dominance. Studies have shown associations between the levels of testosterone.
Some researchers propose that the prevalence of both right-handedness and left-handedness is advantageous for the survival and diversity of the population, promoting genetic variability.
Enhanced cognitive functioning and specialization in tasks may have contributed to the evolution of hand dominance, as different areas of the brain.
Adaptation to societal expectations and the prevalence of right-handed tools and structures may have influenced the predominance of right-handedness.
Mixed-handed individuals may display different hand preferences for activities such as writing, throwing, or using utensils, indicating a partial dominance of one hand over the other in specific tasks.
