Why hasn’t left-handedness been removed from the gene pool?

Left vs. right handedness is interesting. You’d think that natural selection would eventually remove left handedness from the gene pool, as most people are right handed, and we live in a world catered to this majority. South Paw boxers, for example. Any right-handed fighter expects to encounter a right-handed opponent, but when a left handed opponent steeps up, it quite often works in their favor. Same with baseball. Back in medieval times, the staircases would spiral upwards clockwise to make it difficult for intruders to have a full swing with a sword, as they might hit the banister. At the top of the staircase, on the other hand, the right handed swordsmen, on the other hand, have a wide swing radius, making it easier to defend.

    Genes is the short answer here for how people are born left handed. Here’s a link that I found interesting on the topic should you like to read more about it: http://www.ibtimes.com/science-how-why-left-handers-are-so-uncommon-916273

    Personally, I don’t think left handedness should be done away with. They make things interesting in my opinion.
