In the mitochondrial DNA of Drosophila, it has been discovered that different mutations can cause the lifespan of men to be affected. The mutations to not have the same result on the lifespan of women however. In the United Kingdom, by the age of 85, there are around 50 percent more women than men in the population. By the age of 100, there are twice more than that. This does not only take place in humans but in most other animals too. Colleagues at Monash University, located in Australia, found out that the mitochondria contain mutations that affect the aging of male aging but not female aging. This is because the mitochondria are passed from the mother. Mutations that harm males can build in the mitochondria DNA. This mutation slips through natural selection. Of course the main reasons women outlive men is due to social behavior, lifestyle, and hormones. We do see the difference in male mitochondria from females and it plays a small role nonetheless.
