The unintentional creation of “sturddlefish” hybrids may illuminate the genomic mechanisms that govern whether species can interbreed.
Readers simulated the genetics of dog breeding to solve a puzzle about mixed breed percentages and sexual reproduction.
Solve a puzzle about mixed dog breeds, sexual reproduction and the COVID-19 pandemic.
In their search for sources of genetic novelty, researchers find that some “orphan genes” with no obvious ancestors evolve out of junk DNA, contrary to old assumptions.
We give our genes and our environment all the credit for making us who we are. But random noise during development might be just as important.
Clues from fish diversity suggest that interbreeding between species could be a major mechanism of fast speciation.
Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.
For more than six decades, the influential biologist Edward O. Wilson has drawn connections between evolution, ecology and behavior, often sparking controversies inside and outside of science.
Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
