Researchers conclude that humans have reached their maximum biological limits

In France, a first of its kind review spanning 120 years’ worth of historical information suggested that humans may have reached their maximum limits for height, lifespan and physical performance. 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. Rather than continually improving, the team concludes that we will see a shift in the proportion of the population reaching the previously recorded maximum limits.
However, when researchers considered how environmental and genetic limitations combined may affect the ability for us to reach these upper limits, our effect on the environment was found to play a key role.
