The lifespan of first ten generations, from Adam to Noah (excluding Enoch – the 7th generation). Enoch was excluded because he did not die but was translated to heaven at age 365 (Gen 5:24; Heb 11:5). The trend-line is nearly flat showing that life expectancy during this time was nearly stable, with most of these patriarchs living to be over 900 years. This may suggest a very low mutation rate during this period. The actual Patriarchs and their ages are shown in table 1.
