Examining the extent of coevolution between fungus-farming ants and the bacteria that live on their exoskeleton
A study investigates the evolution of beneficial bacteria that live inside and on the surface of farming ants. Attine ants farm fungi, in one of the natural world's best-studied mutualistic symbioses. In the 1990s, the picture ...

One of the earliest examples of a winged seed found in a mine in China
A team of geologists, life scientists and biologists affiliated with several institutions in China has found one of the earliest examples of a winged seed in a mine in Anhui Province. Their paper is published in the journal ...
Evolution in real time: Scientists predict—and witness—evolution in a 30-year marine snail experiment
Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population ...

Playing songs to Darwin's finches helps confirm link between environmental change and emergence of new species
They say that hindsight is 20/20, and though the theory of ecological speciation—which holds that new species emerge in response to ecological changes—seems to hold in retrospect, it has been difficult to demonstrate ...
