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

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

People typically think about evolution as a linear process where, within a species, the classic adage of "survival of the ...

The gut microbiome is complex, and can be affected by the things we eat, our physical habits, our genes, and other factors.

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 ...

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 ...

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, ...

Bacteria are among the most diverse and ancient forms of life on Earth. Yet, much of what is known about them comes from a ...

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 ...
