Average Life Span before the common era and during the common era
Answers
Unhygienic living conditions and little access to effective medical care meant life expectancy was likely limited to about 35 years of age. That's life expectancy at birth, a figure dramatically influenced by infant mortality—pegged at the time as high as 30%.
Answer:
The scientists deduced that lifespan only greatly increased—that is, past the age of 30 or so—about 30,000 years ago, which is rather late in the course of human evolution. This was done by comparing the fraction of those who died early with those who died at an earlier age.
Explanation:
When all mortality rates for that particular population are taken into consideration, life expectancy refers to the average lifetime of the entire population. The actual length of a person's life is gauged by their life span.
Life expectancy was probably just around 35 years due to unhygienic living conditions and limited access to quality medical care. That is the life expectancy at birth, which is significantly influenced by infant mortality, which was estimated to be as high as 30% at the time.
