Rapid evolutionary escape by large populations from local fitness peaks is likely in natureDaniel M Weinreich
Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, Massachusetts 02138, USA
Evolution 59:1175-82. 2005..Thus, counterintuitively, mass selection alone offers a biologically realistic resolution to the problem of evolutionary escape from local fitness peaks in natural populations...
Perspective: Sign epistasis and genetic constraint on evolutionary trajectoriesDaniel M Weinreich
Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, Massachusetts 02138, USA
Evolution 59:1165-74. 2005..These theoretical and empirical considerations imply that strong genetic constraint on the selective accessibility of trajectories to high fitness genotypes may exist and suggest specific areas of investigation for future research...
Darwinian evolution can follow only very few mutational paths to fitter proteinsDaniel M Weinreich
Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, MA 02138, USA
Science 312:111-4. 2006..This implies that the protein tape of life may be largely reproducible and even predictable...
The rank ordering of genotypic fitness values predicts genetic constraint on natural selection on landscapes lacking sign epistasisDaniel M Weinreich
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts 02138, USA
Genetics 171:1397-405. 2005..This statistical association is robust to population size, permitting general inferences about some of the characteristics of fitness rank orderings responsible for genetic constraint on natural selection...
Mutational reversions during adaptive protein evolutionMark A DePristo
Department of Organismic and Evolutionary Biology, Harvard University, MA, USA
Mol Biol Evol 24:1608-10. 2007..Altogether, this discovery highlights the unusual and potentially circuitous routes natural selection can follow during adaptation...
Temporal constraints on the incorporation of regulatory mutants in evolutionary pathwaysKyle M Brown
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA, USA
Mol Biol Evol 26:2455-62. 2009..A mathematical model of beta-lactam resistance is examined in detail and shown to be consistent with the observed results...
Missense meanderings in sequence space: a biophysical view of protein evolutionMark A DePristo
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts 02138, USA
Nat Rev Genet 6:678-87. 2005..We then advance a biophysical model of protein evolution that helps us to understand phenomena that range from the dynamics of molecular adaptation to the clock-like rate of protein evolution...
Patterns and mechanisms of genetic and phenotypic differentiation in marine microbesMartin F Polz
Department of Civil and Environmental Engineering, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139, USA
Philos Trans R Soc Lond B Biol Sci 361:2009-21. 2006....
Stepwise acquisition of pyrimethamine resistance in the malaria parasiteElena R Lozovsky
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138, USA
Proc Natl Acad Sci U S A 106:12025-30. 2009..Our results also suggest an explanation for why I164L is detected in Southeast Asia and South America, but not at significant frequencies in Africa...
Widespread genetic exchange among terrestrial bacteriophagesOlin K Silander
Department of Biological Sciences, University of California at San Diego, 9500 Gilman Drive, La Jolla, CA 92093, USA
Proc Natl Acad Sci U S A 102:19009-14. 2005..This extraordinary rate of genetic exchange between highly unrelated individuals is unprecedented in any taxa. We discuss our results in light of the biological species concept applied to viruses...
Empirical fitness landscapes reveal accessible evolutionary pathsFrank J Poelwijk
FOM Institute AMOLF, Kruislaan 407, 1098 SJ, Amsterdam, The Netherlands
Nature 445:383-6. 2007..With this first view on empirical evolutionary landscapes, we can now finally start asking why particular evolutionary paths are taken...
