Scientists Uncover LUCA: The Mysterious Organism That Gave Rise to All Life on Earth

New research has revealed groundbreaking insights about LUCA (the Last Universal Common Ancestor), the organism that all life on Earth can trace its origins to. Scientists have discovered that LUCA, which existed around 4.2 billion years ago, was not a simple organism but a complex one that shaped early ecosystems and played a key role in the evolution of life.

In this video, we dive deep into the recent study led by the University of Bristol, which traces LUCA’s timeline and uncovers the genetic and ecological traits that allowed it to thrive in Earth's harsh early environment. LUCA had a genome capable of encoding over 2,600 proteins, a sophisticated immune system, and an anaerobic metabolism, suggesting it was far more complex than previously thought.

We also explore the implications of these findings for understanding life’s emergence on Earth and the possibility of life on other planets. From ancient microbial warfare to LUCA’s role in early Earth ecosystems, this discovery sheds new light on the origins of life itself.
