The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a new study. It is the first time researchers use data from protein shapes and combine it with data from genomic sequences to improve the reliability of evolutionary trees, a critical resource used by the scientific community for understanding the history of life, monitor the spread of pathogens or create new treatments for disease. Crucially, the approach works even with the predicted structures of proteins that have never been experimentally determined. The findings open the door to using the massive amount of structural data being generated by tools like AlphaFold 2 and help open new windows into the ancient history of life on Earth.
From 2000 to 2022, the US legally imported almost 30,000 different species of plants and animals, from songbirds to reptiles
A marine crustacean that looks like Darth Vader’s helmet has been recognised as a new species, but it could be under threat from trawling due to its popularity in Vietnamese restaurants
An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: how the ventral nerve cord, a key component of the central nervous system, evolved in ecdysozoan animals, a group that includes insects, nematodes, and priapulid worms. Their findings provide valuable insights into the origins of these structures in the basal Cambrian period.

Prehistoric kangaroos in southern Australia had a more general diet than previously assumed, giving rise to new ideas about their survival and resilience to climate change, and the final extinction of the megafauna, a new study has found. The new research used advanced dental analysis techniques to study microscopic wear patterns on fossilized kangaroo teeth.
A recent study has uncovered the surprising evolutionary origin of the mammalian outer ear, linking it to the gills of ancient fish and marine invertebrates. The research reveals that both structures are composed of elastic cartilage and shares gene control elements that hint at their connection. This finding sheds new light on the evolution of the mammalian ear, highlighting how structures can transform over time to serve new functions.
Sabre teeth can be ideal for puncturing the flesh of prey, which may explain why they evolved in different groups of mammals at least five times
A new study finds that one of the hottest periods in Earth's history may have driven lampreys apart -- genetically speaking. The work could have implications for how aquatic species respond to our current changing climate.

Researchers have unearthed two fossils, named Punk and Emo, revealing that ancient molluscs were more complex and adaptable than previously known.
Evolution has resulted in the development of both herbivores and carnivores -- but how? What type of food did extinct vertebrates eat? And how can we gain insight into the diets of these creatures? In living animals, we can simply observe what they feed on today. In the case of extinct species, however, researchers rely on morphological or chemical information supplied by fossils. A team has now compiled a reference framework of isotope compositions indicating the type of diet for extant reptiles that represents a useful reference dataset to reconstruct the diet of fossil reptiles.

Two species of marine molluscs dating back about 430 million years have been named Punk and Emo for their outlandish spiky appearance
A new study has outlined the first genomic evidence of early migration from New Guinea into the Wallacea, an archipelago containing Timor-Leste and hundreds of inhabited eastern Indonesian islands.
A newly described dinosaur whose fossils were recently uncovered is challenging the existing narrative, with evidence that the reptiles were present in the northern hemisphere millions of years earlier than previously known.
