Lifespan, which can be defined as the process by which a living thing continues its life, gives information about human position in the evolutionary process and adaptation to changing conditions. Humanity has struggled with diseases since the past and striving to improve conditions, delay aging, prolong healthy lifespan. In ancient hunter-gatherer communities, who slept in tree branches or lived in caves, and faced various dangers every day, mortality at a young age was common. Societies struggling with famine, war and epidemics for many years had a very short lifespan, the difference between birth rate and death rate was small. The human being was less exposed to danger with the shift from the hunter-gatherer lifestyles to settled agricultural societies. Lifespan has gradually increased, thanks to the improving health and hygiene conditions, developments in technology and medicine. The species lifespan contributes to comprehending their role within the taxonomic classification. For this reason, in this study, the impact of changing conditions on life expectancy has been examined, by comparing the diets, illnesses, and medical facilities of societies lived in prehistoric and historic periods with those of today's societies. Whether the human life has a maximum limit has been explained, and it is aimed to interpret the estimated lifespan that awaits us in the future.
