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 ...

Animal social interactions could speed up evolution
Scientists typically predict how species evolve by looking at their genes and the environment they live in, but new research from the University of Aberdeen has highlighted a key factor that's often overlooked: social interactions, ...

Researchers find dragonfly species with darker wings have evolved to withstand heat and attract partners
Temperature determines where species can live and if they are threatened by a warming climate. So, for a long time, biologists studied how heat tolerance affects survival. Yet, less is known about how thermal traits influence ...

In studying the mating rituals of fruit flies, scientists may have learned something about how brains evolve
Male fruit flies have several tricks for finding a mate, from sensing pheromones in the dark to relying on visual cues in the light. Now, new research reveals that these tiny suitors are leveraging a flexible network of modular ...

Genomic study reveals fungal domestication by leafcutter ants
While our human ancestors began domesticating food crops around 10,000 years ago, a lineage of ants called the "attines" became fungus farmers 60 million years earlier. The attine ants and their fungal crop mutually depend ...

Asteroid that wiped out the dinosaurs may have led to the invention of 'ant agriculture'
The event that wiped out the dinosaurs wasn't all bad. The low-light environment caused by the meteor impact some 66 million years ago favored the spread of fungi that feed on organic matter, which was abundant at the time ...

Genetic database shows some fungal crops became completely reliant on ants 27 million years ago
When humans began farming crops thousands of years ago, agriculture had already been around for millions of years. In fact, several animal lineages have been growing their own food since long before humans evolved as a species.
