We all have one common ancestor. Since the DNA of all organisms has the same four bases, this similarity may point to the origin of life on Earth (adenine, thymine, cytosine, and guanine).

A common ancestor is someone from whom you and another individual or group of individuals can trace your lineage. Since you are also their descendants, the term can technically be used to refer to any of their relatives as well as the common ancestor you descend from.

An organism, which derives its name from the ancient Greek for "instrument of an instrument", is any organic living system that functions as an independent entity. Cells make up every living thing (cell theory). It is called an organism.
