Scientists over several years have debated on  perspectives about menopause and gave out many different hypothesis on menopause exists.. Men and Women have it very differently when it comes to reproduction, men can still "bear" children with 96 contrary to women who become decrepit. Among several assumptions, a handful of scientists believe that it is because women after reproducing to a certain limit , should give more attention to taking care of her children , also because as the woman ages her chances of having miscarriages and death during childbirth gets meaningfully higher. In addition to the previous assumption , other scientists believe that women go through menopause because it provides the women to become a grandmother and help raise her grandchildren . This hypthesis was made according to the Finland reseachers who studied their country's population records that before the industrial revolution, children were most likely to live till adulthood if their grandmothers were still alive. Menopause therefore might be a winning evolutionary strategy because it leads to more grandchildren who carry on the grandmother's genes. On the other hand several scientists question if it is even necessary to think of menopause as a special adaptation in humans. Supported by the fact that what happens to women as they get older is not so different to what happens to females of othe species, because in many species females are born with a supply of eggs that then gradually deteoritate over their lifetime.
