The Rapa Nui diving beetle has been rediscovered after almost 100 years – and it is rewriting its own evolutionary story. #remote_ecosystems #islandbiodiversity #Dytiscidae #EasterIsland

So happy to share my first PhD chapter! First digital brain endocast of Hoplitomeryx matthei - a strange five-horned ruminant from Gargano paleo-island (Italy).

Great article by Kaifu and colleagues on early Homo floresiensis: dwarfism evolved in about 300 thousand years. Reminds me of dwarf elephants, where we found similar rates of dwarfism 🏝️⌛️#islands #rapid_evolution

@JuanCarlosIll18 so protecting their current habitat is not enough, as it is suboptimal at its best

[Alexandra van der Geer @IslandEvolution]

well-said: "the final populations of all moa species persisted in suboptimal habitats in cold, mountainous areas that were generally last and least impacted by people". This applies to all remaining insular endemic species, not only flightless birds 😢#vulnerable #extinction_risk

The skull of the small ruminant Hoplitomeryx (Pleistocene of Italy) has such a Sauron vibe ! #fossilfriday
