African infants have had a greater chance of survival if they have a living maternal grandmother who is without young children of her own. this fact has been used to support an evolutionary explanation of:

Grandmother hypothesis

Explanation:

Grandmother hypothesis states that a woman with a living grandmother in close proximity will tend to have more children and mortality of the children will be reduced because of the help that will be rendered by the grandmother.

A Simon Chapman, a student at the University of Turku in Finland also supports this hypothesis, He reported that having a grandmother age 50 to 75 increased a toddler's chance of surviving from age 2 to 5 by 30 percent.
