Why Are Some People Left-Handed?

The video explores the evolutionary and genetic aspects of handedness, focusing on why most humans are right-handed. It discusses the challenges faced by left-handers in a predominantly right-handed world, including cultural and linguistic biases. The video delves into brain asymmetry, language processing, and genetic theories, such as the right shift mutation, to explain handedness. It also presents alternative theories related to embryonic development and brain asymmetry. The video concludes by highlighting the societal role and potential advantages of left-handedness, suggesting that diversity in brain function contributes to human creativity and adaptability.
