The human race has PEAKED: Study says we have hit the limit for height, lifespan and physical performance - and could soon move backwards
Experts say that many of today's sporting records may never be beaten. Pictured, Usain Bolt of Jamaica celebrates after running his final race in home country during the Racers Grand Prix at the national stadium in Kingston, Jamaica, on June 10, 2017.
Experts analysed 120 years worth of historical information, and concluded maximum limits for height, lifespan and physical performance have been met.
'Human height has decreased in the last decade in some African countries; this suggests some societies are no longer able to provide sufficient nutrition for each of their children and maintain the health of their younger inhabitants,' Prof. Toussaint explains.
WHAT CAN BE DONE?
To avoid us being the cause of our own decline, the researchers say they hope their findings will encourage policymakers to focus on strategies for increasing quality of life and maximize the proportion of the population that can reach these maximum biological limits.
'Now that we know the limits of the human species, this can act as a clear goal for nations to ensure that human capacities reach their highest possible values for most of the population,' said Professor Jean-François Toussaint from Paris Descartes University, France.
'With escalating environmental constraints, this may cost increasingly more energy and investment in order to balance the rising ecosystem pressures.
However, if successful, we then should observe an incremental rise in mean values of height, lifespan and most human biomarkers.'
Prof. Toussaint warns however, 'The utmost challenge is now to maintain these indices at high levels.'
