The unintentional creation of “sturddlefish” hybrids may illuminate the genomic mechanisms that govern whether species can interbreed.
Clues from fish diversity suggest that interbreeding between species could be a major mechanism of fast speciation.
Researchers agree it’s a long shot, but transmissible cancers could theoretically evolve into independent species. Certain weird parasites might be living proof.
Researchers struggle to incorporate ongoing evolutionary discoveries into an animal classification scheme older than Darwin.
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
By reconstructing prehistoric food webs and analyzing the diverse interactions of humans with other species, the ecologist Jennifer Dunne is developing a new understanding of sustainability through network science.
The first animal genus defined purely by genetic characters represents a new era for the sorting and naming of animals.
Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.
Modelers find evidence that a combination of competition, predation and evolution will push ecosystems toward species diversity anywhere in the universe.
