Plasmids are found in bacteria as extrachromosomal pieces of DNA that replicate separately from the host chromosome. They are a common repository of genes encoding antibiotic resistance, and ...

At the start of life, the origin of a primitive genome required individual replicators, or genes, to act like enzymes and cooperatively copy each other. The evolutionary stability of such enzymatic ...

An international team of researchers including limnologists from the University of Konstanz shows that rapid genomic changes during antagonistic species interactions are shaped by the reciprocal ...

When scientists attempt to understand how climate change might reshape our environment, they must grapple with the seemingly endless complexity of interacting systems. For those considering the likely ...

In a recent study entitled "The feedback between selection and demography shapes genomic diversity during coevolution", which is due for publication in Science Advances on 2 October 2019, researchers ...

Webs of mutualistic species often expand as new species are introduced. Here a female Anna’s hummingbird visits a Mexican bush sage in a California garden. (Photo by John Thompson) Coevolution, which ...

When scientists attempt to understand how climate change might reshape our environment, they must grapple with the seemingly endless complexity of interacting systems. For those considering the likely ...

In a recent op-ed published in Proceedings of the National Academy of Sciences, SFI External Professor Michael Hochberg and co-author Paul Rainey explore whether deepening interdependence between ...

Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have ...
