Biochemistry Supports Bible’s Long Life Spans

TNRTB Archive - Retained for reference information

Another biochemical study on aging makes the long life spans recorded in Genesis 5 and 11 scientifically plausible. Researchers demonstrated that the adverse effects of aging on the immune system can be delayed by caloric restriction. Such a measure has been known to dramatically extend the life expectancy of model laboratory organisms due to the mediation by the sirtuin family of enzymes. It appears that indirectly affecting the activity of these enzymes delays aging in primates. If scientists can significantly influence life spans by simple biochemical intervention, it is not unreasonable to think that a Creator could adjust human biochemistry to permit long life spans and then shorten them after the Flood. In light of this study, the long human life spans described in Genesis are scientifically reasonable.

In 1999, I left my position in R&D at a Fortune 500 company to join Reasons to Believe because I felt the most important thing I could do as a scientist is to communicate to skeptics and believers alike the powerful scientific evidence—evidence that is being uncovered day after day—for God’s existence and the reliability of Scripture.
