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 ...

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

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 ...

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

“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 ...

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, ...

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

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

The results revealed a clear sequence. Enzymes predating cannabis showed no ability to process CBGA. The first enzyme unique ...

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

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 ...
