Living sharks are often portrayed as the apex predators of the marine realm. Paleontologists have been able to identify fossils of their extinct ancestors that date back hundreds of millions of years to a time known as the ...
Within the cabinets and drawers of the world's herbaria are nearly 400 million dried plant specimens. These collections have long served as a vital record of what plant species exist on Earth and where they grow. But hidden ...
Barnacles are special crustaceans usually enclosed by calcareous plates, and attach themselves firmly to marine substrates such as rocks, boats, and other animals.
When the first humans moved out of Africa, they carried their gut microbes with them. Turns out, these microbes also evolved along with them.
The human gut microbiome is composed of thousands of different bacteria and archaea that vary widely between populations and individuals. Scientists from the Max Planck Institute for Biology in Tübingen have now discovered ...
Wild tomato relatives Solanum habrochaites and S. galapagense are important germplasm donors in modern tomato breeding. Compared to the cultivated tomato, they display many desirable traits, particularly high tolerance to ...
After a comprehensive study of plants across the United States, researchers have arrived at the unexpected conclusion that plants able to fix atmospheric nitrogen are most diverse in arid regions of the country. This finding ...
A team of researchers affiliated with several institutions in Argentina has found chromosomal evidence of people living in South America as far back as 18,000 years ago. The group has published a paper describing their work ...
The brushtail possum asked the sugar glider, "Are we related?" For many years, science answered "No". For a long time, genetic data provided evidence that the Australasian possums, the Phalangeroidea (including the brushtail ...
An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to attach to and infect host ...
