Humans may have reached their maximum limits for height, lifespan and physical performance. A recent review suggests humans have biological limitations, and that anthropogenic impacts on the environment - including climate change - could have a deleterious effect on these limits.

This review is the first of its kind spanning 120 years worth of historical information, while considering the effects of both genetic and environmental parameters. Despite stories that with each generation we will live longer and longer, this review suggests there may be a maximum threshold to our biological limits that we cannot exceed.
A transdisciplinary research team from across France studied trends emerging from historical records, concluding that there appears to be a plateau in the maximum biological limits for humans' height, age and physical abilities.
"These traits no longer increase, despite further continuous nutritional, medical, and scientific progress. This suggests that modern societies have allowed our species to reach its limits. We are the first generation to become aware of this" explains Professor Jean-Fran├žois Toussaint from Paris Descartes University, France.
Rather than continually improving, we will see a shift in the proportion of the population reaching the previously recorded maximum limits. Examples of the effects of these ...
