The effect of mutational robustness on the evolvability of multicellular organisms

This study investigates how mutational robustness affects evolvability in multicellular organisms using a Boolean model, finding that high robustness is favored in stable environments but lower robustness is advantageous after environmental change.

Rapid evolution of the functionally conserved gap gene giant in Drosophila

This study shows that essential developmental genes can undergo functional divergence while maintaining conserved developmental outcomes, challenging the idea that such genes are evolutionarily protected.

Population genetics of the highly polymorphic RPP8 gene family

The paper investigates the polymorphism of the RPP8 gene family in Arabidopsis, finding that balancing selection contributes to its high diversity despite low heterozygosity.
