DNA Study of Neanderthals Suggests Humans Could Live Up to 200 Years.

Research on Modern Human Lifespan

According to TSN.ua: A new study indicates that modern humans have the biological potential to live up to 200 years. This finding emerges from a comparison of Homo sapiens' longevity with the significantly shorter maximum lifespans of Neanderthals and Denisovans. By analyzing DNA methylation data from 15,283 samples, researchers were able to calculate a theoretical upper limit for human lifespan. This type of epigenetic analysis provides a novel way to estimate biological aging across species.

Comparing Longevity Across Human Relatives

The maximum lifespan for Neanderthals was between 38.2 and 64.5 years, while for Denisovans it ranged from 40 to 69.8 years. In stark contrast, the study found the absolute upper bound for modern humans could be between 128 and 202 years. The analyzed samples included individuals from birth to 114 years old, with 219 people being over the age of 90.

Interestingly, respiratory tract tissues were found to have the shortest potential lifespan, estimated between 128.3 and 155.1 years. The research also notes that the capacity for extended longevity likely evolved after Homo sapiens split from the lineages of Neanderthals and Denisovans. These insights could prove valuable for future scientific work in gerontology and the study of aging.

These results open new horizons for understanding the mechanisms of aging and potential pathways for extending human life.

They may stimulate further research in genetics, medicine, and biotechnology aimed at identifying the factors that influence lifespan. Defining a theoretical limit to human life is also likely to spark new ethical debates concerning aging, resources, and societal structures in the future.
