Genetic architecture and balancing selection: the life and death of differentiated variants
Balancing selection describes any form of natural selection, which results in the persistence
of multiple variants of a trait at intermediate frequencies within populations. By offering up a …

Co-option of the trichome-forming network initiated the evolution of a morphological novelty in Drosophila eugracilis
Identifying the molecular origins by which new morphological structures evolve is one of the
long-standing problems in evolutionary biology. To date, vanishingly few examples provide …
