The universal genetic code, used by nearly all living organisms may be in need of a rewrite
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 ...
A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, ...
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 ...
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: ...
Blue chromosome DNA and gradually glowing flicker light matter chemical when camera moving closeup. Medical and Heredity genetic health concept. Technology science. 3D illustration rendering “Today, ...
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 ...
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 ...
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 ...

There’s a gene in our DNA that seems to come from an infection by an ancient virus—but no one knows its true purpose
You're walking around right now carrying the genetic fingerprints of infections that happened millions of years ago. Deep inside your cells, woven into the very fabric of your DNA, sit sequences that ...
Analysis of ancient proteins may fill in the gaps of human evolution left by the decomposition of DNA. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
Important, previously unrecognized genetic changes common to all ancient and modern Homo sapiens spread in Africa more than 300,000 years ago, a new study finds. After that, the same investigation ...
