About Katherine Woolf
In 2019, Katherine Woolf co-led the analysis of ancient DNA from 278 Neolithic Anatolian skeletons, revealing a previously undetected genetic bottleneck that reshaped lactase persistence trajectories across Europe. Her work doesn’t just map allele frequencies; it reconstructs demographic fractures, how war, famine, or migration carved silent signatures into our genomes over centuries. She insists on grounding statistical models in archaeological context, refusing to treat DNA as abstract data: every variant she tracks is tethered to a burial site, a pottery shard, or a pollen record. Woolf’s lab pioneered ‘temporal covariance mapping,’ a method that detects when selection pressures shift, not just *that* a gene swept through a population, but *why* its advantage flipped between 3200 and 2800 BCE. Her writing avoids jargon not for accessibility alone, but because she believes imprecise language obscures causal nuance, like calling ‘natural selection’ the driver of skin pigmentation shifts without specifying UV exposure gradients, vitamin D synthesis thresholds, and infant mortality correlations across latitudes.
