When Charles Darwin first proposed how evolution works in 1859, it seemed plausible. Tiny changes stack up over time, eventually leading a species to become something entirely different. Aside from ...

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

Researchers have identified evolutionary hotspots in DNA where mutations are more likely. The study authors say these findings will help us in the future to predict the evolution of bacteria and ...

The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...

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

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

DNA codes offer new evidence of evolution. DNA, the genetic blueprint for living things, is like a text made up of chemical letters. For many decades, reading the sequence of letters in DNA was a ...

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected long ...

In a recent study published in the journal Genome Biology and Evolution, researchers examined the differences in circadian biology between the ancestors of modern humans and the archaic hominins such ...
