Subdecadal phytolith and charcoal records from Lake Malawi, East Africa imply minimal effects on human evolution from the∼ 74 ka Toba supereruption
The temporal proximity of the∼ 74 ka Toba supereruption to a putative 100–50 ka human
population bottleneck is the basis for the volcanic winter/weak Garden of Eden hypothesis,
which states that the eruption caused a 6-year-long global volcanic winter and reduced the
effective population of anatomically modern humans (AMH) to fewer than 10,000 individuals.
To test this hypothesis, we sampled two cores collected from Lake Malawi with cryptotephra
previously fingerprinted to the Toba supereruption. Phytolith and charcoal samples were …
