The Short Answer
So there is definitely a tendency towards right handedness in people, but I would also point out that right now, there is social pressure on that as well: many left-handed children born in the 90s were forced to acclimate to right-handedness. When I was in preschool, I had to wear a sock on my left hand all day every day to force me to use my right hand. Right-handedness has been found in our early human ancestors (about 2 million years ago) but not in our chimp relatives, which means that there is probably an effect of evolution on hand preference. A gene variant was discovered in 2014 that appears to increase your odds of being left-handed. So while the science isn't settled, I would say that right-handed is the default and somewhere along human evolution, a series of small gene mutations, makes people favor their other hand.
