Chimpanzees are very similar to humans, and a recent study has found another way they are like us.
Most chimps, like most humans, are right handed.
Researchers studied 114 chimps in Zambia. They placed food in tubes and then closely watched the chimps to see which hand they used.
It turned out that the right hand was the dominant hand in most cases.
Also, more of the female chimps used their right hand than the males, which is another similarity, since more women are right handed than men.
It was said that the use of a dominant hand “had traditionally been considered exclusively human and had been believed to be caused by asymmetries observed in the human brain that are related to the realization of complicated activities that require the use and coordination of both hands.”
This is pretty interesting!
It just shows how genetically similar we are to primates!
