The term associated with the single-celled ancestor theory is "Last Universal Common Ancestor" (LUCA). This theory postulates that all living organisms on Earth trace back to a single-celled organism from which all life evolved.
The single called ancestor theory is also known as the monogenism theory, which proposes that all humans are descended from a single pair of ancestors. This theory contrasts with the polygenism theory, which suggests that different groups of humans have separate origins.

Evolution.
The theory that states organisms evolved from a common ancestor is the theory of evolution proposed by Charles Darwin in his book "On the Origin of Species" published in 1859. Darwin's theory of evolution by natural selection explains how species change over time through the process of adaptation to their environments.
