The acceleration of evolutionary spread by long-range dispersal
Oskar Hallatschek, Daniel S. Fisher
The spreading of evolutionary novelties across populations is the central element of adaptation. Unless population are well-mixed (like bacteria in a shaken test tube), the spreadi…
Asexual Evolution Waves: Fluctuations and Universality
Daniel S. Fisher
In large asexual populations, multiple beneficial mutations arise in the population, compete, interfere with each other, and accumulate on the same genome, before any of them fix.…
Genetic Diversity and the Structure of Genealogies in Rapidly Adapting Populations
Michael M. Desai, Aleksandra M. Walczak, Daniel S. Fisher
Positive selection distorts the structure of genealogies and hence alters patterns of genetic variation within a population. Most analyses of these distortions focus on the signatu…
Rate of Adaptation in Large Sexual Populations
Richard A. Neher, Boris I. Shraiman, Daniel S. Fisher
Adaptation often involves the acquisition of a large number of genomic changes which arise as mutations in single individuals. In asexual populations, combinations of mutations can…
Beneficial mutation-selection balance and the effect of linkage on positive selection
Michael M. Desai, Daniel S. Fisher
When beneficial mutations are rare, they accumulate by a series of selective sweeps. But when they are common, many beneficial mutations will occur before any can fix, so there wil…
