SpainThe article explores the evolutionary mystery behind why approximately 90% of humans are right-handed, a phenomenon observed across cultures and time periods. It explains that this high prevalence of right-handedness is not unique to humans, many animals exhibit lateralization, but among humans, the consistency is striking. Researchers like Miquel Llorente suggest that this pattern may be linked to brain structure, particularly the dominance of the left hemisphere for language and motor control. The hypothesis proposed is that early human communication began with hand gestures, which were predominantly performed with the right hand, leading to the co-evolution of language and right-handedness. The article notes that while some non-human species show similar patterns, such as certain birds, the extent of population-level lateralization in humans remains largely unexplained.
Bias read (Center): The article presents scientific research and hypotheses about human handedness without taking a political stance. It discusses biological and neurological factors rather than ideological positions, making it apolitical in nature.
