1.4-million-year-old skull fragments linked to mystery human ancestor.

@Gizmodo reports: "The fragmentary facial bones belong to Homo affinis erectus, an esoteric offshoot of our family tree that inhabited Spain more than one million years ago."

Deep-sea fish study reveals evolutionary marvels in Earth's hadal zone phys.org/news/2025-03-deep-sea

#Evolution and genetic adaptation of fishes to the deep sea sciencedirect.com/science/arti

"they confirmed a century-old hypothesis about deep-sea #fish evolution involving two distinct pathways. 'Ancient survivors' colonized the deep sea before the #Cretaceous mass #extinction, while 'new immigrants' account for the majority of modern #DeepSea species that emerged after the #MassExtinction."

The biological world is awash in #chemical signals.

Some molecular messages find their targets; most linger unread in the environment.

But sometimes, other #species — chemical eavesdroppers, bystanders or visitors — can pick up and interpret the signals in their own way.

If the message is powerful enough, the impact can ripple out across an #ecosystem.

Lieben Dank, @h0ldi 🙏

Aus meiner Sicht ist erst einmal entscheidend, dass gerade auch wissenschaftlich Denkende akzeptieren: Charles #Darwin hatte Recht - auch die Religiosität ist ebenso wie z.B. die Musikalität ein Ergebnis der #Evolution. Religiöse bilden kooperative Gemeinschaften, die sowohl lebensförderlich wie aber auch gewalttätig werden können. Entsprechend kommt es auch hier auf Dialog, Wissen & dialogischen Monismus an.

Computer simulations suggest that evolution itself could be evolving, depending on environmental pressures, meaning that the processes that change living things get revised as well. @ScienceAlert tells us why “this ain’t over yet.”

How popular crab memes amplify mistaken ideas about evolution.

Opinion piece from @SciAm: "Memes about repeated evolution of crabs have been co-opted to joke about technology and 'ultimate forms.' They’re hilarious, but they oversimplify natural variation, giving bad arguments a scientific veneer."

Ancient glacier finding reveals clues to how complex life on Earth evolved.

From @CNN: "Research published in the journal Geology suggests the flowing of ancient glaciers may have directly shaped chemical changes in the ocean that were critical for the evolution of complex organisms."

CNN · Ancient glacier finding reveals clues to how complex life on Earth evolved, scientists sayGlaciers once inched toward the sea, gouging rocks. When the ice masses melted, they infused oceans with nutrients that may have shaped how life evolved, a study found.

The #Pokémon generation, like many before theirs, largely doesn't understand that biological #evolution is not directional. Evolution is not a tale of progress. It's just differential procreative success in the face of changing environments and random genetic drift. It's not headed anywhere. It's as purposeless as the solar system.
