There’s nothing like a big mass extinction to open up ecological niches and clear out the competition, accelerating evolution for some lucky survivors. Or is there? A new study suggests that the rate ...

Robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. At the start of the simulation, a biped ...

A new study examined how bivalves -- the group that includes clams, mussels, scallops, and oysters -- evolved among many others in the period of rapid evolution known as the Cambrian Explosion. The ...

Variation in the ecological niches of closely related or co-occurring species is a key factor that underpins evolutionary diversification and extinction. Niche breadth regulates the diversity of ...
