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 ...

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 ...

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 groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as ...

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 ...

Genetic sharing among evolutionary neighbors all happens through hybrids: the offspring produced when individuals from two ...

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, ...

Researchers have used CRISPR to switch back on a gene that vanished from the human lineage roughly 20 million years ago, ...

Woodrats weigh less than half a pound but can survive venomous rattlesnake bites that would hospitalize, or even kill, a full ...

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 ...

When a snake displays its fangs, it’s showing off one of evolution’s greatest weapons. This is because snake venom is not a ...
