The often-mentioned fact that humans and chimpanzees are 99.9 percent identical in their DNA is hard to accept for some people, who can't comprehend how we could share so much of our basic genetic ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

The genetic code, a universal blueprint for life, governs how DNA and RNA sequences translate into proteins. While its complexity has inspired generations of scientists, its origins remain a topic of ...

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 ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.

Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.

In this AI-generated illustration of Earth at the dawn of life, a distant volcano towers over shallow pools of water. It is possible the earliest life forms evolved in such environments. Credit: ...

Scientists have published nearly the entire genome of the common rat, making it possible to compare it to the genetic maps of people and mice. That ability is expected to yield clues into evolution ...
