Despite the fact that the life expectancy in the past century of both sexes has increased, across the world, women on average still older. This difference may be genetically determined.

In the study of the American Duke University studied researchers of data from more than 1 million people worldwide, dating from the eighteenth century to the present. The past century saw humanity the most significant increase in life expectancy.

The researchers compared the results with the life expectancy of non-human primates. Because the gender gap in these animals also prevents, think researcher Susan Alberts that the difference is “evolutionarily deeply rooted”.

How big the difference in life expectancy between men and women, varies from country to country. So is the biggest difference to be found in the contemporary Russian society. There is the gender gap approximately ten years. This is in contrast to the population in countries like Nigeria and India, where the difference is much smaller.

The results of the research are published in the Proceedings of the National Academy of Sciences.
