Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that early human populations followed a distinct survival curve characterized by high infant mortality?

Yes. Demographic and archaeological evidence from human hunter-gatherer and prehistoric populations consistently demonstrates a survival curve characterized by high infant and juvenile mortality.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The claim is specific, empirical, and falsifiable. Papers [0], [4], and [7] all examine the demographic profiles, survivorship curves, and mortality rates of human foragers and prehistoric populations, which characteristically display high infant and juvenile mortality before leveling off. None of the retrieved papers refute this well-established evolutionary demography finding.
