🦥Per milioni di anni i bradipi si sono evoluti in forme e dimensioni diverse. Poi è arrivato Homo sapiens. Una nuova ricerca su Science ricostruisce la loro storia. Ne abbiamo parlato con il primo autore, Alberto Boscaini Alberto Boscaini. Domani su #Pikaia. Foto: A. Boscaini

Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report in Science that this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures.

Thrilled to see our work on sloth evolution finally published! Huge thanks to Alberto Boscaini and Daniel Casali for bringing me on board for such a fascinating project! 🦥 #evolution #paleontology #paleobiology

Per decine di milioni di anni i bradipi si sono diversificati in una varietà di forme e dimensioni, adattandosi a diverse nicchie ecologiche. Poi è arrivato Homo sapiens. Una nuova ricerca su Science racconta l’ascesa e la caduta di questo gruppo buff.ly/wUJn8WF

Gracias a CONICET Dialoga por difundir nuestro trabajo. - Un exhaustivo estudio sobre los perezosos gigantes realizado por científicos del CONICET llegó a la revista Science Magazine: conicet.gov.ar/un-exhaustivo-…

Siempre agradecido con CONICET y toda la Argentina por permitirme hacer lo que amo. Aguante la ciencia argentina!

🦥🌴 Gracias CienciaEs por la maravillosa entrevista, donde Alberto Boscaini y yo tuvimos la oportunidad de hablar sobre perezosos y evolución a raíz de nuestro último trabajo en Science Magazine #paleontología #evolución #paleobiología

More than 1,000 scientists took to the streets yesterday in Buenos Aires and other cities in Argentina wearing gas masks to protest the collapse of science in the country, which they say was initiated by their government. go.nature.com/43SZ4Vi

🦏🦣🦌 LARGE paper alert!!! We tracked 60 million years of large herbivore evolution—over 3,000 fossil species—to uncover how ecosystems have changed and reorganized through time. What we found might help us understand the next big tipping point 🧵👇 nature.com/articles/s4146…

Why did some #megafauna survive? 🦣🦘🦌 Our new study shows #extinction risk was higher for larger, flat-footed, island species & lower for those closely related to tropical African/Asian fauna, likely filtered by earlier #hominid impacts👣🍖 doi.org/10.1111/geb.70… #palaeolithic

New isotopic and fossil evidence suggests that early primates, including hominins, began eating grasses long before their bodies evolved the traits needed to process them efficiently—findings that support the long-hypothesized concept of behavioral drive, researchers report in
