Science Explains Why There Aren't Many Who Are Left-Handed

Lefties aren't common. They represent only about 10 percent of the human population, but a new a study is suggesting the reason they are in the minority isn't anything suspect. It boils down to the fact that the human race cooperate more than they compete.
Researchers from Northwestern University have analyzed real world data to establish if the existing hypothesis that cooperation breeds same handedness is correct. Daniel M Abrams explains to SciGuru:
"The more social the animal—where cooperation is highly valued—the more the general population will trend toward one side. The most important factor for an efficient society is a high degree of cooperation. In humans, this has resulted in a right-handed majority."
The hypothesis suggests that everybody would have the same dominant hand, and it should in theory, help us share things like tools.
Abrams' analysis confirms the speculation, which pretty much means the remaining 10 percent of lefties represents the fact that the human rice isn't entirely cooperative.
The new model created by the researchers can predict the percentage of left handers in any group, humans, bids or sports men given data about the degrees of cooperation and competition within social structures. The results are published in The Journal of the Royal Society Interface.
