Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

Je nach Wirtsvogel legen Europäische Kuckucke ganz unterschiedliche Eier. Genetische Analysen zeigen, wie diese Anpassung vererbt wird, ohne dass es zur Aufspaltung der Art kommt.

Extra-pair copulations might be a suitable strategy to circumvent the fitness costs of interbreeding.

Chromatin modifications provide a substrate for epigenetic variation with evolutionary potential. To quantify the contribution of this layer of variation during speciation in crows, we leveraged geno...
