What are some of the causes to the left hand to be dominant?

Left-handedness is believed to be influenced by a combination of genetic, environmental, and neurological factors. Studies suggest that genetics play a role, with left-handedness often running in families. Additionally, prenatal factors, such as hormone exposure and birth complications, may also contribute. Neurologically, differences in brain hemisphere dominance and processing could impact hand preference, leading some individuals to be left-handed.
