Hot Topic Origins Origin & Evolution of Life
Untangling the Tree of Life
Topic: Origin & Evolution of Life
A new study describes a suite of novel techniques that could help scientists resolve contradictions in evolutionary studies and provide greater accuracy when deciphering branches on the tree of life.

Study Reveals Important Step in Photosynthesis Evolution
Topic: Origin & Evolution of Life
New research provides definitive proof that green algae eat bacteria. The findings provide clues about how early organisms acquired chloroplasts - structures responsible for converting light into food.

RNA’s Hidden Abilities on Ancient Earth
Topic: Origin & Evolution of Life
A new study shows that RNA may have a more varied role in the cells of ancient organisms on the early Earth.

The Smell of Ancient Earth
Topic: Origin & Evolution of Life
Scientists have discovered tiny fossils in rocks around Lake Superior, Canada, that provide the first evidence of organisms eating each other. The study provides insight into Earth's ancient biosphere, and might indicate what our planet used to smell like.

What Happened to the Dinosaur's Predecessors?
Topic: Origin & Evolution of Life
Newly discovered fossils from 10 million years after Earth's largest mass extinction show that the ancestors of dinosaurs may have appeared much earlier than previously thought.

Ocean Ice Tubes Provide Clues to Life's Origin
Topic: Origin & Evolution of Life
A new study indicates that brinicles, sometimes called "sea stalactites," could have played a role in the origin of life. The findings might have implications in understanding life's potential on icy moons in our solar system.

Star- and Planet-Forming Regions May Hold Key to Life's Chirality
Topic: Origin & Evolution of Life
New research may help explain why life on Earth is made of left-handed amino acids. The study indicates that circular polarization in star- and planet-forming regions could affect the formation of organic material, such as amino acids.

New Study Points to Proteins and Salt for Life's Origin
Topic: Origin & Evolution of Life
A new study indicates that 10 amino acids believed to exist on the early Earth were capable of forming foldable proteins. The research suggests that these proteins could have been used in biological reactions in the first living cells.

Decoding the DNA of One of Earth's Great Survivors
Topic: Origin & Evolution of Life
Scientists have decoded the genome of one of Earth's most abundant turtle species. The findings can teach us a lot about evolution and the unique survival strategies of turtles.

The Power Behind the Primordial Soup
Topic: Origin & Evolution of Life
A new study shows that molecules similar to those used in generating energy in modern cells may have been formed on the early Earth when meteorites containing phosphorus crashed in the pools of hot, acidic liquid near around volcanoes.
