No, they are correct - that is generally what happens when people compare historic life expectancy rates to modern times. And, people are using 'lifespan' and 'life expectancy' as if they were interchangeable (they're different things). Your Wikipedia source states up front that the linked research is old and questionable, with the cited paper dating back over 50 years. More recent research, some of it linked here [0], does indeed point to a significantly longer life expectancy. No idea why Wikipedia is using incorrect 55 yo data for this one; but it does help to prove OP's point further. 0 - https://rewild.com/in-depth/longevity.html https://rewild.com/in-depth/longevity.html
