    The argument that Paleo must be unhealthy because “the average caveman only lived to be 25” is a perfect example of how easy it is to draw false conclusions from true statistics. Consider the two statements below. 1. The average caveman lived to be 25. 2. The average age of death for cavemen was 25. The first sentence describes a cultural norm, usi...

    The factor skewing the “average” data and giving rise to the false assumption that cavemen died very young is the infant mortality rate. This is difficult to determine using records from actual Paleolithic populations. While researchers have attempted to determine the age at death of Paleolithic humans by analyzing bone remains, these procedures me...

    This argument is not simply a set of statistics derived from studies on modern hunter-gatherers and extrapolated to the Paleolithic on the assumption that living conditions would be essentially similar. It also has a basis in human biology, specifically reproductive biology. Assuming that a Paleolithic woman wanted to maximize her baby’s chance for...

    The evolution of menopause and the mathematical impossibility of population growth are two gaping holes in the hypothesis that Paleolithic humans died at 25. Available data from modern hunter-gatherer societies also contradict the hypothesis that prehistoric humans all died very young: members of these groups who live to reach puberty have life exp...
