Trends in DNA methylation with age replicate across diverse human populations

The paper identifies age-related DNA methylation patterns in African hunter-gatherer populations and shows that genetic variation at meQTLs influences these associations.

The evolutionary advantage of heritable phenotypic heterogeneity

This study investigates how phenotypic plasticity confers evolutionary advantages by analyzing fixation probabilities of plastic alleles under different environmental conditions and heritability levels.

Worldwide patterns of human epigenetic variation

The paper measures DNA methylation across diverse human populations and finds it is more population-specific than gene expression levels, suggesting stronger genetic control of methylation.

The evolution of genetic diversity in changing environments

This study uses theoretical models to explore how fluctuating selection shapes the evolution of recombination, mutation, and migration rates, showing their similar responses to environmental changes.

The Role of Migration in the Evolution of Phenotypic Switching

This study uses a population genetic model to show that spatial variation in selection pressures influences the evolution of phenotypic switching, with migration affecting switching rates depending on environmental similarity across space.
