Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and simplification is a much more ...

The ability to tolerate toxic substances can help animals find new food sources and thrive in certain ecological niches. Researchers at the Max Planck Institute for Chemical Ecology in Jena have now ...

Recent progress in genomics has revealed that gene loss is a pervasive source of genetic variation. Nevertheless, it is unclear whether most gene loss-of-function mutation fixations are neutral or ...

Deep within the dark caves of northeastern Mexico lives a fish that has spent hundreds of thousands of years adapting to a ...

Experimental evolution of microbial adaptation employs controlled laboratory regimes to observe real‐time evolutionary change in bacteria, yeasts and other microbes. By propagating populations under ...

The maned wolf has its own genus, so it’s not actually a wolf. But the South American canid is the tallest in the world, standing 3 feet at the shoulder. Its long legs help it peer over the tall ...
