Our mystery deer paper is finally out! We used ancient DNA to clarify the systematics of Torontoceros hypogaeus, an 11k years old fossil discovered during excavation work for the Toronto subway in 1976. Due to its unique antler morphology, it was described as an extinct deer species, but ...

Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos
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...

Blau, weiß, grünlich: Wie schafft es der Kuckuck, seine Eierfarbe an unterschiedliche Wirtsvögel anzupassen? LMU-Forschende zeigen: Die Farbe wird über die Mutterlinie vererbt – das ermöglicht Anpassung ohne Aufspaltung in spezialisierte Populationen. @mpiforbi.bsky.social www.lmu.de/de/newsroom/...
Kuckuck: Mütterliche Gene sorgen für verschiedenfarbige Eier
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.

Is there an independent role of epigenetic variation in speciation? We looked for answers in the crow hybrid zone.
In brief: DNA seems to be in the driving seat.
Congrats Justin! This was a long journey.
