Some complexities in interpreting apparent effects of hitchhiking: a
commentary on Gompert, Feder & Nosil (2021)
Abstract
We write to address recent claims by Gompert et al. (2021) about the
potentially important and underappreciated phenomena of “indirect
selection”, the observation that neutral regions may be affected by
natural selection. We argue both that this phenomenon – generally known
as genetic hitchhiking – is neither new nor poorly studied, and that
the patterns described by the authors have multiple alternative
explanations.
