Archaea, a unique domain of life, were discovered in the 1970s in extreme environments such as hot springs and salty lakes, with notable early studies conducted in locations like Yellowstone National Park in the United States. Initially considered unusual bacteria, their distinct genetics and biochemistry led to their recognition as a separate domain, emphasizing microbial diversity and evolutionary complexity.
