Perspectives of Homo sapiens lifespan extension: focus on external or internal resources?

Figure 2. The lifespan equality and life expectancy in humans (black and green) and non-human primates (blue) (from [49], with minor modifications). The y axis shows lifespan equality, the log of the inverse of the Keyfitz’s entropy; corresponding values of the Keyftiz’s entropy are given in parentheses on the y axis.
