Rapid evolution: New findings on its molecular mechanisms

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed that geographical barriers ...

Scent brings all the songbirds to the yard

Chickadees can smell! That is the news from a study out of Lehigh University, the first to document naturally hybridizing songbirds' preference for the scent of their own species.

When plant roots learned to follow gravity

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The how and when of this evolutionary step has, until now, remained unknown. Plant biologists at the Institute of Science and ...

Software to protect the world's most endangered species

By combining genetic and environmental databases, researchers at EPFL are seeking to help biologists identify more accurately the animal and plant species most exposed to climate change, in order to develop appropriate conservation ...
