A delicate woodland fern discovered in the mountains of France is the love child of two distantly-related groups of plants that haven't interbred in 60 million years, genetic analyses show. Reproducing after such a long evolutionary breakup is akin to an elephant hybridizing with a manatee, or a human with a lemur, the researchers say.

Studying aging and its associated diseases has been challenging because existing vertebrate models (e.g., mice) are relatively long lived, while short-lived invertebrate species (e.g., yeast and worms) lack key features present in humans. Scientists have found a new middle ground with the development of a genome-editing toolkit to study aging in the naturally short-lived African turquoise killifish.
