After a nose swab tests positive for a virus or bacteria, scientists can use the sample’s genetic sequence to figure out where and when the pathogen emerged and how fast it’s changing.
Bat hosts, lab leaks – tracing SARS-CoV-2 to its origins involves more than just tracking down patient zero.
How scientists discovered the ‘Popa langur’ was a separate species of just 200 monkeys.
There are fundamental knowledge gaps around coral in the Great Barrier Reef, including how many species live there and where they’re found. Our new study finally starts to fill those gaps.
New research shows animal evolution often involves losing genes and becoming less complex.
It’s likely our species doesn’t actually have a single origin.
Using the family relationships between single-celled protists alive today, researchers hypothesized what their evolutionary ancestors looked like – and then looked in the fossil record for matches.
Most animal groups adopted their shapes quickly but some kept evolving.
