Live Science’s latest science word explainer highlights the term “abiogenesis,” a word often used in discussions about how life may have first appeared. In simple terms, abiogenesis refers to the idea that life emerged naturally from nonliving matter.

The term is commonly linked to questions about the origin of life and the earliest conditions on Earth. It points to a process in which basic chemical building blocks may have eventually given rise to the first living systems.

Because the subject sits at the intersection of biology, chemistry and Earth science, abiogenesis remains an important concept in scientific education and popular science coverage. It is often introduced when explaining how scientists think about life’s beginnings without relying on already existing organisms.

For readers encountering the word for the first time, the key takeaway is straightforward: abiogenesis is the scientific term for the natural emergence of life from nonliving materials. That makes it a central word in any conversation about where life came from.
