Have you ever wondered why people have a preference for using one hand over the other? What is it that determines hand dominance? Is it because of evolution, is it hereditary, or due to something else? SciShow takes a quick look at the topic in this terrific video.
Special Note: As mentioned in the YouTube comments section, we wish the video had addressed the issue of ambidexterity in people as well.
Do you find yourself preferring one hand over the other almost exclusively for all activities? Are you someone who mixes things up and uses one hand or the other predominantly for specific activities? Perhaps you are an individual who falls into the ambidextrous category? Share your thought and experiences in the comments!
