Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution ...

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

A novel iLDS statistic uncovers adaptive gene sweeps in gut bacteria, highlighting evolutionary responses to modern diets and enhancing microbiome studies.

“Expression tells us what cells do, but regulatory DNA tells us where they come from, how they develop, and which germ layer ...

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 ...

De novo gene evolution describes the process by which entirely new genes originate from previously non-coding DNA rather than from the duplication and divergence of existing genetic material. This ...

Gut bacteria rapidly adapt to processed food additives, revealing how modern diets can reshape microbial evolution worldwide.

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

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, ...

For millennia, evolution has intrigued many great thinkers, prompting questions about how new traits emerge as species adapt over time. Then, attention shifted to natural selection and the inheritance ...
