Archaeological records-paintings, drawings and carvings of humans engaged in activities involving the use of

hands- indicate that humans have been predominantly right-handed for more than 5,000years. In ancient Egyptian

artwork , for example, the right hand is depicted as the dominant one in about 90 percent of the example. Fracture or

wear patterns on tools also indicate that a majority of ancient people were right- handed.

Cro- Magnon cave paintings some 27,000 years old commonly show outlines of human hands made by placing

one hand against the cave all and applying paint with the other. Children today make similar outlines of their hands with

crayons on paper. With few exceptions, left hands of Cro- Magnons are displayed on cave walls, indicating that the

paintings were usually done by right- handers.

Anthropological evidence pushes the record of handedness in early human ancestors back to at least 1.4 million years

ago. One important line of evidence comes from flaking patterns of stone cores used in tool making :implements flaked

with a clockwise motion ( indicating a right- handed toolmaker) can be distinguished from those flaked with a counter-

clockwise rotation ( indicating a left- handed toolmaker).

Even scratches found on fossil human teeth offer clues. Ancient humans are thought to have cut meat into strips

by holding it between their teeth and slicing it with stone knives, as do present-day Inuit. Occasionally the knives slip

and leave scratches on the users’ teeth. Scratches made with a left-to –right stroke direction ( by right-handers) are more

common than scratches in the opposite direction ( made by left- handers).

Still other evidence comes from cranial morphology : scientists think that physical differences between the

right and left sides of the interior of the skull indicate subtle physical differences between the two sides of the brain.

The variation between the hemispheres corresponds to which side of the body is used to perform specific activities.

Such studies, as well as studies of tool use, indicate that right- or left-sided dominance is not exclusive to modern Homo

sapiens. Population of Neanderthals, such as Homo erectus and Homo habilis, seem to have been predominantly right-

handed, as we are.
