An ancient fossil breaks nature’s secret life code
Scientists have long believed that a universal genetic code serves as a blueprint for all life on Earth, dictating the structure and function of organisms from the simplest bacteria to complex humans.
Living organisms share an ancestor called the last universal common ancestor, or LUCA. LUCA is estimated to have lived ...
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 ...
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: ...
