Its stability and timing have been accorded significance in terms of evolution, maximal fitness and the onset of ageing. The nadir of mortality in developed nations now lies at years, significantly predating fertility at a mean of This differential fall in mortality has resulted in England and Wales primarily but not exclusively from reductions in accidents and deaths from congenital anomalies.

This suggests that environmental and lifestyle factors play a major role. Natural selection refers to the adaptive traits of an organism.
According to evolutionary theories, aging is based on natural selection. It says that an organism begins aging after they have reached their peak of reproduction and have passed down adaptive traits. Another theory is that biochemical reactions cause aging. These reactions occur naturally and continuously throughout life. In recent decades, life expectancy around the world has increased.
This is due many factors, including:. In most parts of the world, women live longer than men. This is due to several biological, social, and environmental factors.
Women, on average, have more estrogen than men. Estrogen is the female sex hormone. In contrast, the male sex hormone testosterone may suppress the immune system.
