Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
This year marks half a century since the discovery of Lucy, a hominid fossil that would go on to drastically alter our understanding of human evolution. The man who unearthed her, Donald Johanson, shares more about the momentous excavation and the legacy it has left.
A strain of green algae has been artificially evolved to turn carbon dioxide into sustainable fuel and plastic
The graft involved in trying to bring the peregrine falcon, Hawaiian crow and California condor back from the brink in the US makes for compelling reading in Feather Trails by Sophie Osborn
Tulip trees have a structure that is somewhere between hardwood and softwood – called "midwood" – which could increase their ability to store carbon
Fossils in rocks that are 3.8 billion years old have puzzled biologists as they look nothing like modern cells, but now it seems they may be an ancient precursor life form that was unable to control its structure
The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.

Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Elephant-like species started going extinct faster when early humans evolved, and the rate of extinction rose even higher when modern humans appeared
Ants and other insects are capable of astounding navigational feats. Perhaps an appreciation of this could aid conservation efforts, says Robert Barrie
Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

The 166-million-year-old fossils of an adult and a juvenile of the same extinct mammal species reveal that they had longer "childhoods" and lifespans than similar species today
An orange layer on the tips of Komodo dragons’ teeth may give the enamel extra strength for ripping apart their prey
Researchers are calling for greater protection for basking sharks after a camera on a tagged shark recorded a collision for the first time
Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.
