In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

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 ...

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, ...

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 ...

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 ...

SALT LAKE CITY - Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. In some instances it might be more appropriate to call it an ...

In an article published in the journal Nature Communications, scientists have studied a protein, called HP1, which is involved in organizing DNA. Present in both fission yeast and mammals, this ...

DNA repair pathways exist to correct molecular damage caused by internal and external factors. However, any damage to these pathways can result in the creation of tumors and specific types of cancers.

The oldest DNA ever recovered from an animal is adding new chapters to mammoth life history, going back more than 1 million years. The findings “really highlight the exciting times that we live in,” ...
