Evolution is always happening — so why can't we see it? A biologist explains the timescale problem, election pressure, and ...

MADS-box genes, critical regulatory elements in eukaryotes, have undergone extensive diversification in green plants. Although MADS-box genes have been extensively studied, the understanding of their ...

A moss gene previously thought to have been inactive actually plays a key role in its evolutionary success, researchers from ...

In contrast to cnidarians that host photosymbionts intracellularly, giant clams harbor symbionts extracellularly, within an elaborate network of tubules derived from the digestive system 19. The ...

Assessing the relative roles of chance and necessity in evolution is of wide interest, but it requires evolving the same population under the same environment multiple times—a virtually impossible ...

Scientists have uncovered thousands of bacterial DNA fragments hidden inside cockroaches for millions of years. The ...

“Where are all the genetic cures?” asks Denis Noble, a frustrated biophysicist, Royal Society fellow and pioneer of the field of systems biology. “They don’t exist. Where will they be? They won’t ...

Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept ...

Genes are not passed on exclusively from parents to their offspring. Some are mobile and can also jump to other species, as ...

The evolution of new genes is not the only way for a species to change. The loss of genes may also lead to adaptations that help species survive, but this idea has not been well studied. Now, ...
