Sup, iam Marie Mesa, G’day, mate.
Well, it’s no secret that there are a lot of theories out there about why some kids are left-handed. From genetics to environment, the causes of left-handedness can be complex and varied. But hey, let’s take a closer look at what might be behind this phenomenon!
What Causes A Child To Be Left-Handed? [Solved]
Well, it looks like Dad’s got the final say when it comes to whether your kiddo is left- or right-handed. In 2007, scientist Clyde Francks discovered a gene called LRRTM1 that’s passed down from the old man and determines which hand your child will use. Pretty cool, huh?
Genetics: It is believed that genetics play a role in determining whether a child is left-handed or right-handed. Studies have shown that if both parents are left-handed, there is a higher chance of the child being left-handed as well.
Brain Development: The development of the brain can also influence handedness in children. Research has suggested that the right hemisphere of the brain develops faster than the left hemisphere, which can lead to more dominant use of the left hand for certain tasks.
Environment: Environmental factors such as exposure to certain activities or objects may also influence handedness in children. For example, if a child is exposed to activities that require them to use their left hand more often, they may become more comfortable using it and eventually become predominantly left-handed over time.
Injury: In some cases, an injury or trauma to one side of the body can cause a person to favor their other hand for certain tasks due to pain or discomfort on one side of their body when performing those tasks with their dominant hand
There are a few potential causes for why a child might be left-handed. It could be genetic, as some research suggests that it runs in families. It could also be due to the environment they’re in; if they’re around other lefties, they may pick up the habit. Lastly, it could just be random chance - some kids are just born that way! Whatever the reason, being left-handed isn’t anything to worry about - it’s totally normal!
