Archaea: A New Domain of Life

Archaea are a group of microscopic organisms that are similar to bacteria but form their own distinct domain of life. They often live in extreme environments, like hot springs, salt lakes, or deep underground, where few other organisms survive. Unlike bacteria, archaea have unique molecular features in their genetics and cell structures. They play important roles in processes like nutrient cycling and can even influence climate. Recognized as a separate domain alongside Bacteria and Eukarya, archaea help us understand the diversity and complexity of life on Earth.
